Description

System Updated: I added a pc-based music server, something I had been contemplating for the past year or so. The opportunity presented itself when a friend was preparing to scrap a Dell C521 low-profile desktop computer. I fitted it out with a a 2.4 GHz AMD Athlon 64 x2 processor, 2 GB RAM, Windows XP Pro, iTunes 9, USB 2.0, Musiland Monitor 01 USD and Blue Jeans Cable BNC/BNC digital cable. Digital bitstream is fed to the S/PDIF in on my Wadia 16. I shuffled a few things around and have sited my ARC LS5 Mk. III on a Black Diamond Racing Shelf with two sets of #4 cones and placed the PC on the Towhshend Seismic Sink. Things sound just a little tighter, with greater impact and more image specificity. This move supplements the tweak I implemented recently, fabbing an acoustic treatment which hangs from the plasma screen in my listening room. The treatment employs three ASC Sound Planks, which are oriented horizontally. Otherwise, I've had the same audio system for going on 12 years and made only minor adjustments to it. This system, more than any I have owned before (and there have been a few) communicates the emotion and magic of the music. The system is situated in a lower level dedicated listening room. Walls were constructed using two layers of 5/8" drywall on 16" stud centers. Floor is concrete slab and is covered with the best fiber-based padding I could find and wool carpet. There are four dedicated 20-amp circuits on isolated grounds, as well as one separate 15-amp circuit for non-audio ancillaries. Room dimesions are the closest I could get to golden-rule proportions. The room is prewired for a future plasma screen and Magnepan 5.1 surround system, however, I'm a two-channel guy at heart. The room is treated with RPG abfusers (side walls), RPG bass traps (front corners), ASC tube traps (rear corners) and ASC Sound planks (front wall). Measured performance of the room/system combination is really pretty good (up 5 db at 80 Hz is the only real anomaly). A non-audio feature of the room is an ultra-quiet vent fan situated above the hot seat, which I installed so I can smoke the occasional cigar. Make-up air is supplied by a large thru-wall return vent. It was a nice idea but I have only smoked one cigar in the room so far. The fan is effective for venting heat generated by the tube amp, however. Overall, I'm pleased on this, my third and hopefully last, dedicated listening room adventure.

Components Toggle details

    • Wadia 16
    VRDS disc clamping system, digimaster D/A conversion, 80 MIPS processing, 24-bit resolution, balanced outputs, 45 lbs. Sound compares favorably to newer players, so I haven't been able to bring myself to upgrade it.
    • Dell C521
    Music Server - AMD Athlon 64 x2, 2.4 GHz, 2 GB RAM, Windows XP Pro, iTunes 9, USB 2.0, Musiland Monitor 01 USD, Blue Jeans Cable BNC/BNC digital cable.
    • VPI Industries Aries
    I have been very pleased with this table. I am just now considering the addition of the new Mini Super Feet and SDS from VPI. The table is sited on a Bright Star base designed for the Aries, which I have found to be quite effective.
    • VPI Industries JMW Memorial
    Unipivot design, easy to adjust and swap out for another. Sonic characteristics can also be tuned by increasing/decreasing the amount of damping fluid in the cup.
    • Benz Micro Glider
    This cartridge mates well to the JMW Memorial arm and Aries table. I prefer it to my van den Hul One
    • van den Hul MC-One
    Very low output and very pleasing sound, though I prefer my Benz Micro Glider. Alignment can be difficult due to the short cantilever.
    • Audio Research LS-5 mkIII
    To my ears, an absolutely terrific preamp. Dynamic and clean with great bloom. A keeper.
    • Audio Research VT-200
    I love this amp. An absolutely synergistic match with the Magnepan 3.5Rs, and there is not much it will not drive.
    • Magnepan MG-3.5r
    I'm a real fan of their sound, especially with the ARC VT200. The transparency, reproduction of acoustic instruments and voices, and the soundstaging are, in my opinion, superb.
    • Vandersteen 2wq
    Supplementing the Magnepan 3.5Rs with a pair of these was one of the best investments I've made in my system, allowing the Maggies to do what they do best and releiving the amp/speakers of the need to reproduce the lowest frequencies. I'm running them balanced with the optional Vandersteen high pass filters.
    • Kimber KCTG and KCAG
    Balanced throughout, with the exception of the run from turntable to phono preamp.
    • Audioquest Emerald
    Balanced 9-meter run from preamp to amplifier. Great cable.
    • Audio Research PH-3
    A nice phono preamp. I will probably send this to ARC in the not-too-distant future for upgrading to SE.
    • Audioquest Clear
    Bi-wired 8-foot run from amp to main speakers.
    • Kimber 8TC
    One 8-foot run from amp to each subwoofer.
    • Kimber Homemade
    Kimber 8TC with a copper ground lead down the center, connected to Hubbell connectors and jacketed in a woven sleeve.
    • Audio Power 116
    Just for that extra measure of protection and filtering
    • Audio Power PE-1
    Though there are claimed benefits to sound, I like it for the reason that I am able to monitor line voltage.
    • Black Diamond Shelves and Cones
    Under CD player and phono preamp, each using two sets of three cones.
    • Townshend Seismic Sink
    Under preamp
    • Sound Anchor VT200
    Situated under VT200
    • Ensemble Tube Sox
    Replacing the OEM damping rings on all 6922s in the LS5 and PH3. A noticeable reduction in microphonics can be attributed to the tweak.
    • Panasonic TH-58PZ800U
    58-inch HD plasma screen TV
    • ASC & RPG Various
    Acoustic treatments, including bass traps, Tube Traps, Abfusors, Sound Planks and Skylines. Devices are applied as required according to room measurements.
    • ASC Sound Planks Plasma Treatment
    Home-brew acoustic treatment for 58" plasma screen TV -- I've got my image back! Today I fabricated a simple but effective acoustic treament to hang on my flat screen. I used 3/4" flat stock to make two hooks for hanging, some velcro and three Sound Planks. The insides of the hooks are covered with velcro (loop side) to prevent damage to the TV. The outside of each hook is covered with velcro which enables two 33" "ribbons" of velcro to hang down. The sound planks are affixed with velcro in a horizontal orientation, helping to tame front wall reflections. The device was a breeze to make, is easily stored and affixes in about 30 seconds for critical listening.
    • Nixie Clock and Single Malts Various
    The Nixie clock blows the Tice clock away. It gets the timing right and is much more analog (and therefore real) in its presentation. The single malts greatly improve soundstage width and depth, take the edge off highs, and make 100 dB sound like 90 dB. Using them I have had occasions where I heard things I didn't know were present on the medium of being played (perhaps they weren't).

Great System, wow, congratulations. Are these self-made acoustic treatment panels?

Jeffnc, When I finished the basement, I instructed the electrician to include my four dedicated 20-amp lines; I told him where I wanted each receptacle placed and made certain each was on its own 20-amp breaker in the breaker box. According to code, each of these receptacles is on a 12-2 line. As a result, there is minimal voltage drop between the breaker box and the outlets. The effect on sound has been profound, especially when I was using a pair of Class-A Krell KMA-160s, each of which drew 8 amps continuously. In my opinion, there's no substitute for a good, stout line feeding the amps.

Dywang1, I am using a pair of the Vandersteen M5-HPB balanced high-pass filters with my system. They are inserted in the signal path between the preamp and power amplifier and may be adjusted for amplifier input impedance. The subwoofers take their input from the output of the amplifier. My final settings for the high-pass filters are as recommended by Vandersteen; I followed the company's setup instructions and have been unable to improve on the recommended settings. The subs are adjustable for Q and speaker sensitivity. My final settings on the subwoofers are identical to the Maggies' sensitivity and the Q is dialed down, which improves integration with my room. Adding these subs and filters was one of the best improvements I have made in my system, improving the midrange response of my main speakers and adding that last octave of bass to the system. Many times you don't even know the subs are there, however, when the music calls for bass, it is there ... and it is good.

In my opinion, there is no substitute for a good, stout line to feed your system. I have read all of the reviews about high-priced power cords and the argument they represent the first four or so feet leading from the equipment to the outlet. However, if the outlet is one of several hanging on a 14-2 line that feeds everything from small appliances to flourescent lights there is going to be an effect on the equipment ... and the quality of the music it can reproduce. I can honestly say installing dedicated lines has had a profound effect on sound quality. First, the voltage is stable. Second, there is no other noise-inducing equipment hanging on the line. And third, when the amps need current, it is available. This is the third room in which I have had dedicated lines. I think they represent a small investment for the improvement they yield in sound quality.

Hello. I think the last thing missing from my system is a dedicated 20 amp line. Just my luck, I hear that a 20 amp line is the most important thing to a system. Your thoughts...

Joe, Such a wonderful system, I adore you.
I am using a Mg3.6R myself and am really interested in the
Vandersteen crossover you mentioned. Could you give me some detail as how was it used and whether I can get one today from Vandersteen or others so I can try on my system.
thanks

dywang1_98

Wow, awesome room, just fantastic. So many people talk about components so much, it's nice to see attention to something that really matters a lot - room acoustics. This is the type of room I dream of having some day!

Can you tell me more about how to set up the dedicated power? I'm really confused about that. Any links to information that can really cut through the clutter and get to important details on how to set this up? thanks

jeffnc

Hi Joe,
Your have done a great job. My system is very simular to your's, right down to the Sound Anchor VT200 stand. A Linn LP12 w/the goodies, ARC PH3, ARC LS25MKII, VT200, Magggie 3.6's, SACD player & asorted cables, power supply & tweeks. I am ready to upgrade my room(remove the 1/4 inch panneling that is on the lower 48 inches of the wall and add new dry wall, sound treatments & carpet) I live in South West Michigan and would love see your system sometime. I think it would be really interesting to hear simular electronics in a different enviroment than mine, your room is a component all its own.
Thanks for sharing your passion.
Dave

I've got a bunch of $$$ planned for room acoustics for next year but I'll need a few Impressionist paintings for the walls to make it look any better than your place. Thanks again for the inspirational pics!

Thanks for the compliment, Barry, and for the sage advice regarding the Mye stands. Since I'm down to the short strokes on my system (at least for the time being), I will definitely consider the stands. In measuring the room acoustics, I took a fairly rudimentary approach: I placed my digital-readout Radio Shack sound pressure meter on a tripod at the listening position and popped in Stereophile test disc #2. I then ran through the warble tone test tracks (20-31) and recorded the spl at each of the respective frequencies. If there was a hump or a dip, I moved the speakers, adjusted the subs or amended the seating position slightly. Eventually, I ended up with relatively good measured response. From here you can alter speaker or seating position some to achieve the desired subjective response if you wish. It's not perfect but it has worked relatively well in my last three listening rooms. This was confirmed in my first dedicated listening room when I had friend who is an acoustical engineer stop by with his spectrum analyzer and pink noise generator. The anomalies I had noted were roughly the same as those he had measured, though his data was much more granular. Careful placement of acoustic treatments also helps. I have a fairly robust and flexible assortment of these, however, I have used pretty much the same elements in each of my last three rooms. Hope this helps. If you're in Michigan, stop by.

Joe.

Very Very nice. The systems great and the listening room is really very beautiful. Send the address-- I'm moving in!!

You mention room acoustics. What did you do to measure room response. That's my next challenge.

Get the Mye stand - well worth it.

Regards, Barry

Thank you for your kind remarks. There is a layer of adhesive between the sheets of drywall and I believe it is green. There is no vibration I can detect. Bass is rock solid, however, and not muddy.

jtori

Do you have any vibrations between the 2 layers of drywall? Did you use green glue between the 2 layers? Room look very nice. Thanks,

Hi, Thank you for the compliment. The front-end equipment is connected to the amplifier using by a 9-meter pair of balanced Audioquest Emerald interconnect. At the time I purchased it (about 10 years ago) it was one step below Audioquest's top of the line cable, Clear. I have no complaints with the cable, and because of the dual-differential configuration it rejects hum, etc.

jtori

Beautiful and well planned dedicated audio room.
How do you interconnected the long run from the side mounted equipment to your power amplifiers in the middle of your speakers?
(Scuse me for my speeling).
Thanks.

Gmorris,

Thanks for the kind words. Our systems are indeed similar in nature. Only changes I'm contemplating at the moment are GNSC modifications to my LS5 Mk. III and PH3 followed by the possible acquisition of a new CD player (not sure which yet).

Joe:

Congrats on a very nice system. We seem to have similar set up. I am very pleased with the sound in my system and plan no major changes (maybe a Ref 3 or LS26). How about yourself?

Scott and Oz,

Thank you for your kind remarks. I suppose our rooms and our selection of equipment are a reflection of our personalities. I have been extremely pleased with the sound of my system and can only think of a few small tweaks I'd like to make, including GNSC upgrades to my preamp and phono preamp.

Joe.

jtori

Beautiful room! I wouldn't change a thing. I used to own 3.5s in a room similar to yours, so I know you are getting some very good tunes. Enjoy!

Excellent job on your room. Maybe one day you can help me out..

Gotta love those Maggies and VT-200! The two are a match made in audiophile heaven! Great system. Let's do get together and listen.

Not only does it sound good, but it looks good too! Mine is more function over form.

Thanks, Tympani, for your kind remarks. Our hobby is one that can be enjoyed on many different levels (technical and artistic). The music is relaxing, and our systems implementation is infinitely perfectable.

jtori

I love your system! I wonder why? Well done sir...
