Description

An update is past due.  Previously, I had tried using a long wall arrangement, and while the room looked very nice, that orientation was hardly ideal from a sonic perspective.   Since this is a dedicated room, I can take some liberties with appearance.  For the most part, this is my man cave.  My wife rarely joins me for listening sessions.  I do have a decent 2nd system downstairs that the family  can enjoy for casual listening.   I've replaced the Coincident Frankensteins with Atma-Sphere M-60s, and my ModWright Sony 5400 ES was sold since it was rarely used after I had the HAPZ1ES modded.  With the benefit of consultation with one of our Audiogon gurus, I extensively modified the speaker crossovers.  This was one of the best things I ever did.  Amazing difference!  Another recent change was removing the old Berber carpeting.  I selected some luxury vinyl planks.  My flooring guy had concerns about using hardwoods in the bonus room, so I went with the flooring you see depicted.  I think it is very attractive and the room sounds much better than when it was carpeted.

Components Toggle details

    • Coincident Speaker Tech Super Victory II
    Full range floor standers in rosewood. I recently rebuilt the crossovers and what a difference!  All of the stock Solen caps and resistors were replaced.  I used a Jupiter Copper foil with a Duelund Silver as a by-pass, followed by a Path resistor, for the tweeter.  A Janzen Alumen-Z and Mills resistor was used for the midrange.  Finally, Clarity CSA and Mills resistors were used for the woofer.  The stock Solen inductors were left in place.   These modifications completely changed the character of these speakers.  Prior to modification, these speakers were laid back almost to the point of being rather boring.  I could not be happier with the results.  I replaced the stock outrigger spikes with Herbie's Audio Lab Fat Gliders.
    • Coincident Speaker Tech Statement Line Stage
    CSL equipped with Psvane WE replica 101D tubes.  I've got an Synergistic Research Black fuse in this unit.  I bought several of those fuses for the system back a few years ago.  The preamp seemed to benefit more that the other components.  The preamp is powered by the PS Audio P-10 via a PS Audio Statement power chord.  I found that the performance of this preamp is noticeably improve by close physical proximity to the Audio Magic Mini Ref II, apparently due to the Mini Ref's pulse gen activity.
    • ModWright Sony HAPZ1
    ModWright HAPZ1 server equipped with Telefunken 6922 tubes. I am using a MW PS 9.0 power supply currently fitted with a Canadian Westinghouse VU-71 rectifier. This rectifier is my favorite 5U4 type tube. I am also using an Audio Magic Illusion Umbilical to the HAPZ1, which offers a substantial improvement over the stock Truth umbilical.   VH Audio AirSine PCs are utilized on both the power supply and server.
    • Mapleshade Custom Design
    The rack is  a custom design 42" wide unit and uses three 4" solid maple shelves.
    • PS Audio P10
    P10 power regenerator. Substantially reduces AC harmonic distortion and allows adjustment and regulation of AC voltage. Power suppy to the P10 is via a Voodoo Air Dragon PC.
    • Audio Magic Mini Ref II
    Power purifier with Pulse Gen II module.
    • Audio Magic Standard PEA modules
    Don't ask me how or why these things work but they do.
    • Audio Magic Blue dot
    Grounds cleaner
    • Wood Shed 1002-3 CD rack
    Large Oak CD rack. Stained to match mapleshade racks.
    • Wood Shed 1002-3 CD rack
    Solid Oak CD rack. Stained to match Mapleshade rack.
    • VH Audio Symmetry Ag Balanced
    This is a really wonderful balanced IC, which I am running from the HAPZ1 to the preamp.
    • Atma-Sphere M-60
    The M-60's were purchased new and I elected to go for both the V-Cap and power supply upgrades.   Having not heard the amps in stock form, I can't say how much improvement these upgrades offer.  I can say that I am very pleased with these amps. They bumped the excellent Coincident Frankenstein 300Bs from the system, which is not an easy task. Power tubes are SED Winged-C 6AS7s.  For the 6SN7 tubes, I am currently using one RCA grey glass in the left back outside position, with a Sylvania Bad Boy in the middle slot and the new Sophia blue glass tubes in the right back outside position.    I recently replaced GE 6SN7 GTAs in the isolated front (driver) position with Shuguang WE plus tubes.  Though the new Sophias and Shuguangs are pricey, I was amazed at the quality of those tubes.  They are just better than the NOS RCA and GE tubes that they replaced.  With the new tubes, there is an immediately noticeable reduction in grain.  Also, the gap between the M-60's and the Coincident Frankensteins has been closed somewhat with respect to the alluring midrange sweetness of a good 300B amp.  Short runs (~ 30") of 12 G Duelund Tin plated feeds the speakers.
    • The Room! Dedicated Listening Room
    The room is a bonus room that has been dedicated for 2 channel listening.  It is roughly 20 Ft long and 13 wide, with 8 foot ceilings, that are beveled at the floor and side wall junctions.  This room has been a bit of a challenge to get right, and I've learned a lot in the process.  I'm a long time Maggie guy, which means I have mostly had systems with limited output below 40 Hz.  I had no idea it could be such a challenge getting full range speakers to achieve their potential.   I'm using a traditional short wall arrangement, with the equipment rack located along the side wall as far back in the room as I could get it.  I have two dedicated 20 Amp circuits feeding all of the equipment with the exception of the amp on the left.   I have 5 bass traps in the room.  I'm using two GIK Soffit traps in the corners behind the speakers along with two Mondo Traps from Real Traps on the walls.  A third Modo Trap is used in one rear corner behind the listening position.  Treatment of the 4th corner is not possible or necessary, since the room door is in that location. The traps significantly improved clarity by reducing excessive decay times.  I also have a couple of homemade traps on the ceiling at the first reflection points.  First reflection points on the side walls was effectively addressed by clever placement of the CD racks.  These were carefully placed and angled out slightly from the side walls.  This arrangement either deflects first reflections back to the front of the room or channels them behind the rack.  I have not yet settled on an approach for addressing first reflections off of the floor.  But imaging is pretty good as things currently stand, which is not all that easy to accomplish in a room with these dimensions.

Cymbop,  Thanks so much!  The system is capable of pure bliss, but I have not quite gotten things totally right just yet.  I have found the Super Victories to be no small challenge in terms of getting them to integrate well into the room.  As I reported in a recent post, the speakers have been moved to the short wall on either side of the window.  They work much, much better there, but now of course early reflections are more of a problem.   I began the process of using room treatments to level the frequency response, reduce low frequency ringing, and cancel early reflections.  I've had the room set up in such a way that I have had the best 3 dimensional imaging I have ever had, but this at the expense of having some pretty deep nulls to the point where certain notes just drop out.  And in the midst of all of this work, I had my 2nd set of Elrog 300b's go out, which broke my heart.  They are superb tubes.  Nevertheless, I persist, and I will find a way to make these speakers work in this room.  By the way, the Super Victory IIs have 92.5 dB efficiency, which means the Frankensteins  work a bit to drive them.  The Coincident Dragons, or perhaps an Atmosphere M-60, might be better choices with these speakers.

bdp, the paint is a custom color I had made at Sherwin Williams.  Look at my post below from Oct 3, 2015.  If you take that formula for an S-W store they can produce the exact color.

bdp,  Thanks.  I really like this color for the room.  I like the way it looks during the day, and I also like the dark color at night when I typically listen with very low lighting.  I've got two floor lamps, and usually have one of them turned on. One 25W bulb for the room gives a nice soft lighting.  BTW,  I've been in the process of installing room treatments and changing from the long wall configuration you see pictured to a more traditional short wall configuration.  The long wall configuration worked pretty well when I had the Coincident Triumph Extreme II monitors in there, but has proven tricky getting the Super Victory IIs to sound good in this room.  Changing to the short wall configuration proved mandatory.  I've added about 5 bass traps from RealTraps and GIK Acoustics so far.  The standard gray color from the two companies is a close match, and looks very good in the room with the green walls.  I suspect when I get done, the room may not look quite as good as before, but it sure does sound a lot better.  Treating this room has been a fascinating project.

Judomaniak, Sorry, I did not see your post.  With respect to the ModWright gear,  I had the Sony 5400ES sacd player for a year before I sent it for modification.  When it came back, I was just stunned at how much better this already good player was.  Blackest background I had ever heard from a source.  Better resolution too.  Also, for what ever reason, the modification really seemed to close the gap between rbcd and sacd.  They both improved, but the redbook improved so much that I no longer sought sacd exclusively.  The HAPZ1 was a whole 'nother beast.  The stock Sony HAPZ1 was already on a level with the ModWright 5400ES.  I sent the HAPZ1 for mods after having it for just a few weeks.  When it came back it outclassed the sacd player to the point where I rarely used it.  I got a nice offer on it last Summer and it is now gone.   Dan Wright is now doing mods on the Marantz player, and claims it is just superb.  So that would be the way to go if you want a player.  If you want a server that can  stream, the Sony is your ticket.

Charles, the only way up for you is the PRE, in my estimation. The acutron tweeter is special. I have not heard the Total Victorys, but based on my experience with the SVIIs so far, I don't think the performance improvement with the ribbons over the scanspeaks is huge. I also think the sloped baffle in the TEIIs, SVIIs, and PREs is pretty important.

I would also like to hear Mr. Blume's comments on the ribbon vs scanspeak. He clearly knows what he is doing, but he is a man of few words, at least with me.

Charles,
A preliminary comment on the ribbons based on not having the speaker positioning dialed in, as judged by my 62 year old ears. I would say that the coincident ribbons do not match the wonderful Maggie ribbons in my old 3.7Rs. That is a very high bar, and remains my personal benchmark for tweeters. The sweetness, purity, and extension in those ribbons is just wonderful. The scanspeak domes in my TEIIs are different from the ribbons in the SVIIs. With respect to coherence, I personally prefer the scanspeaks, which integrate extremely well with the midrange driver. While coherence in the SVIIs is very good, it is not up to the level one hears in the TEIIs or PREs. I can't say these ears detect an improvement in air or extension with the SVIIs over the TEIIs.
I think where the SVIIs show their strength is in reproduction of the low frequencies. I began to shore up the TEIIs with a couple of REL subwoofers, and despite the fact that they really can't be expected to integrate well with the TEs, once one becomes accustomed to hearing the bottom octaves, you really can't go back. The TEIIs and SVIIs are both excellent speakers, but the SVIIs should not be thought of as TEIIs with bass. They are different animals.

Charles, I think my TEIIs use the Scanspeak soft dome, and yes, the ribbon in the Super Victory II is different from both the scanspeak and also from the wonderful ribbons in my Magnepan 3.7s. The Maggie
ribbons were capable of a sweetness that is tough to match, much less beat. I can't say the ribbons in the Super victory IIs match the Maggie ribbons. Do they better the scanspeak soft domes? I'm not sure they do. I will not know for sure until I get the speaker location nailed, at which point I can bring my TEIIs back upstairs for an A/B.

Charles,
Everytime I try to dial in the speaker positioning I get drawn into the music and just listen. That is a good thing, but it is frustrating when I loose my focus for 45 minutes and havent moved toward the goal. However, as you have pointed out, getting drawn into the music and forgetting everything else is the point. More later.

I have received the additional Canadian Westinghouse VU 71 (5U4G) tubes, and now have them in my Coincident Frankensteins and both ModWright power supplies. These are wonderful rectifiers, but nearly impossible to locate. In the Modwright Power supplies (both the PS9.0 and the PS 9.9) it is immediately obvious that these tubes are superior to every other tube I have tried, including Blackburn Mullard GZ34 and Blackburn Mullard CV387 skinny bottles. There is a complexity and sophistication in the upper harmonics that is uncanny. The top end is extended with lots of air, but it is also smooth as silk. Lower registers are strong and well defined. I also found that for the first time, I liked the PS 9.9 more than the PS 9.0 as the supply for the Sony HAPZ1. The 9.9 with the VU-71 was more resolving and dynamic than the 9.0. It will be very interesting to see how the fat bottle Mullard compares in these two supplies.

I have ordered a Mullard High Wycome fat bottle CV387 to evaluate in the PS 9.9 and 9.0.

I want to do a bit more A/B on the difference between the Vu-71s and the Skinny bottle CV387s in the Franks.

Bdp, as promised, the paint recipe.

Colorant.........OZ..32..64..128
B1 black..........--....45...--.......1
G2 new green.--......5....--.......1
N1 raw umber.--....21...1.......1
Y3 deep gold.--......56...--......--

Sherwin Williams I used the top of the line interior in satin, but I would advise matte. The coverage,levelers, and resistance to running, dipping, and splattering are superb. Best paint I have ever used. Made in Cleveland, not Pittsburgh. Audiophile approved!

Al, right, front wall is what I meant. Retirement tip. Watch out for volunteer work. It is a temporal black hole. It has been a hard day. At any rate, I will chew on the info you provided. I do have a dB meter and stereophile test disc, so I can get a feel for pronounced spikes or dips in frequency response. I should give that a try. When you say in the vicinity of 94 Hz, I take it that the dip would not correspond to a discrete frequency, but the dip would be a band of some width centered around that frequency. Correct?

brownsfan

Owner
Timrhu, thanks so much! I am shocked I got my wife to move, but the house is much nicer and she decided she liked eastern Tennessee, (plus she got to retire early) so the pot was sweet enough that she went for it. As far as room treatments, I may get to that eventually, but I don't really perceive any issues with the current long wall set up. I think the reduction in 90 degree angles due to the bevels at the ceiling/wall, plus the CD racks angled into the back wall corners help. Interestingly, the short wall arrangement was really bad. There was a huge mid base emphasis. It would have taken extensive treatment to get that to work.

Owner
Brf and Al, The polarity is correct on my speakers. No issues there. Thanks for the tip on the sliders. Why didn't I think of that? I got by ok with a piece of plywood under the speakers, but I will give the sliders a try. And now that everything is more or less together, I will be playing around with positioning. Anyone got a good protocol? It is a 3 variable deal, distance from wall, distance between speakers, and toe-in-- This was easier with my other room where there was little flexibility. I'm thinking maybe distance between speakers could be optimized first, followed by distance from back wall, followed by toe in?

brownsfan

Owner
Charles, tonality on both speakers is dead on. Differences are in the area of speed, resolution, and coherence. There may also be differences in staging, but I am going to need a lot more time to tweak placement before drawing firm conclusion.

Al, Charles, Mapman and all. I got a couple of hours of listening in with the woofers pointed out instead of in. I listened to a couple of tracks from Appalachian Journey, including a track where Alison Krauss is accompanied by YoYo Ma et.al. I love this music, and I have never heard it sound more delicate and sweet. Not a huge difference, but a noticeable one. This may be a consequence of the reduction in radiated sound towards the tubes, or it could be a consequence of additional burn in on one rather new tube. Regardless of the cause, this was a most welcome refinement. Next up was a Dvorak string quartet by the Vogler quartet on CPO. This is the best quartet recording I own with respect to spacial differentiation of the first and second violins, and yes, this differentiation was quite evident. I noticed that the lower notes from the cello were a little fuzzy, which I have not noticed previously. However, all 4 instruments were well localized spatially. Finally, I listened to Babi Yar, which contains a lot of low strings, typmani, bass drums etc. I was struck by the depth of stage. Layout of the orchestra (2nd violins to the right, double basses in back, percussion in back) was very evident. Here is where I noticed improved coherence of the woofer predicted by Charles. Whereas in the past, strong low frequency information was easily localized spatially as coming from one or the other woofer, now these instruments were reproduced in their correct spatial location in the sound stage. Therefore, my awareness of the woofer as a separate and distinct driver was eliminated. All in all, I think the outward firing woofer arrangement is going to be the way to go. I will do some more tweaking of toe in and space between the speakers. I may put off further refinement until I receive one more tube that is coming in and get some more burn in time. Once I finished getting placement dialed in, I will revisit comparison of the SVIIs with the TEIIs. That will be an interesting exercise. The TEIIs are mini PREs. The SVIIs are a different animal. How is that for a teaser?

Mapman, I assume you are alluding to the potential for vibrations resulting from the inward firing woofers. I certainly agree with your observation. I did not get my Mapleshade rack down here until the end of July, up until which time my equipment was sitting on the floor. When I got everything up on the rack it made a HUGE difference. Because I am using long wall orientation, pulling the speakers forward toward the listening position enough to get the equipment out of the path of radiation from the woofer isn't possible. So outward firing is in principal the way to go in my room. We will see how things sound later today.

brownsfan

Owner
Al, the front baffle is flat in the right to left plane. So there is nothing preventing the outward facing arrangement from being a viable option. I have moved the speakers, but it will be later in the day before I can begin an evaluation. If I can make this work, it is going to be a better arrangement than the inward firing arrangement.

brownsfan

Owner
Erndog and Charles, improved coherence would be welcome. In their current position, the SEIIs do not share the uncanny coherence I have enjoyed from the TEIIs. I should be able to get some boards under the speakers today and get them moved.
I have noticed the Israel uses inward firing as have some others I have known who have side firing woofers.

The speakers reside in the exact location my son and I first positioned them before he returned to school in August. They are 125 lbs each, and have spikes, so I will have to get them up on something that will slide which I intend to do over the next couple of days. Its raining, so I won't be hiking. I do want to try them with the woofers firing out. Since I am using a long wall configuration, they are already closer than normal to the listening position. If I move the speakers closer together, I can move the Franks to the outside of the speakers if I find I like the inward firing arrangement better than firing outward.

I also found a stash of strong VU-71 Canadian Westinghouse rectifiers, which are now on the way from Great Brittan. These tubes are better than the Mullard skinny bottle CV378s in my ModWright Power supplies. I am thinking about bringing in one fat bottle CV378 to compare with the VU-71.

brownsfan

Owner
Charles, thanks. Once I get the positioning dialed in, I will do some more extensive writing on the TEIIs vs the SVIIs.

brownsfan

Owner
AL, indeed and I have had the same thought. I need to get the speakers up on a piece of plywood so I can slide them around. So far, I haven't noticed any microphonics, but the current positioning is asking for trouble. I haven't tried the woofers facing outward yet.

Owner
Thaluza, once I get the SVIIs dialed in a bit more I will post some detailed impressions. At a high level, I was surprised at how different they are from both my Triumph Extreme IIs, which I use in my downstairs system, and the PREs, which I had the opportunity to audition. They are great speakers and do mate well with the Frank's, though one should not discount the lower efficiency. 92.5 dB is probably borderline with the Frank's in some rooms. My long wall arrangement puts the listening position close to the speakers, and the room is not overly large. The room is roughly 22 x 16, with some reduction in ceiling height along the long walls. In a different room, the Dragons or the Turbo may be a better choice.

Bpt, the wall color is a custom blend I had made at the local Sherwin Williams. Give me a couple days and I will pm you the pigment blend. It took three tries to get the look I wanted. It also looks really good in dim light and goes well with the gold and rosewood, as well as the white ceiling and trim.
