Description

this room and system is the result of 10 years in High End audio. my system has been stable for a couple of years (except for transport and amplifier upgrades within the same brand). the room has been in the planning stage for about 18 months and i actually moved in a little over a month ago.

my audio philosphy is to have the system get out of the way of the event. i like as pure and simple a signal path as possible and, at this point, prefer passive to active gain stages. i love all the formats and enjoy having lot's of music.....vinyl is my favorite but i listen to at least 60% digital. the new room really reveals the benefits of SACD over redbook.

the system and room truely allow the event to be recreated before me. i love the way the speakers disappear and i am transported to another place/time.

i have choosen my cables, sources, amps, speakers to have as little of their own sound as possible.

recently, i upgraded my digtial transport from the modified Philips SACD 1000 to the new emmlabs CDSD.....this was a significant step upward in performance.

i have written an article in Positive Feedback regarding my room building experience.....here is a link;

You must be nearing the end of your prev. never ending quest for 'that' sound. Have you considered the philisophical ramifications of getting there?

it has crossed my mind that these next moves appear to be clear 'end game' type things.

however; i actually view my 'end game' as occuring a year or so ago once the room issues were resolved. i was totally happy with everything. the MM3->MM7 and the NHB-108->NHB-458 are simply upgrades in the same realm as what i've had. if i elected to not spend the additional money to do these upgrades i could have stayed 'pat' and lived where i was happily. more significant in my mind has been to cull my herd of any extra gear and stuff that i'm not going to use long term. which to help fund these purchases i've had to sell everything that is not essential.

as far as 'getting there' and it's implications i don't want to get ahead of myself. right now i'm very curious as to simply how the performance will be once it has a chance to work itself out. i'm going to try (:-)) to resist getting carried away initially and allow myself some time to optimize and then to enjoy it before i try to give it perspective and suggest implications.

i'm going to enjoy the ride and the music.

Marc,

i am not a techie either. OTOH my son is a network engineer and so sets everything up for me. he gets on my computer (remotely with 'log-me-in') and fixes stuff when i have a problem. he did all the ripping and loading on my server. i'm even a hunt and peck typist (and a slow bad one to boot). it took lots of pushing to get me away from my silver discs and useing a server.....and all those discs are still in my room. since my server has been down for the last few weeks it's silver disc digital or no digital at the moment for me. i'm not anti disc, only that once you've spent time with a server, great sound files, and a good easy to use interface, that is how you want to do digital. and until you've tried that you won't realize how great it is.

obviously with my commitment to vinyl and tape i love the process of analog listening.

but digital has it's place in my musical enjoyment and a server makes that experience even better.

mikelavigne

Mike, I'm coming from the point of view of a bit of a computer phobe, and a very pro-tactile person. Being in love with analogue, you'd have to shoot me before I give up on the whole fetish of playing lps.
But now servers/downloading is taking over, I'm getting a nostalgic feel for the little silver discs I've been struggling to love since the 80's.
In other words, ripping cds/sacds and downloading are not for me, not for a while yet anyway, and so I'll settle on the best old fashioned but quality way to spin those discs, just like lps.
Lord help me, I still collect LASERDISCS!
Obv. price is critical and the Stahl Tek is well beyond my means. It's just that as a no compromise design I thought you might be swayed by it, certainly before you put pen to cheque for the Darts.
But with your digital direction I can see this might be a blind alley. If you do get a chance to audition it, please convey your thoughts.

Mike, what is the issue with PCM, excuse my ignorance?
i've always preferred dsd/SACD to PCM. i've posted here and around extensively about my perceptions. and lately since i have many hundreds of SACD's ripped to my hard drive that is mostly what i listen to when i'm listening to digital. it does sound more like my analog than any digital i have heard. i do have 4000 CD's burned on my hard drive as well as 1500-2000 hirez PCM files too which do sound 'nice'. nothing wrong with PCM in and of itself until it is directly compared to dsd. and sure there are many great sounding PCM files that sound better than specific dsd files as there are so many varibles in sources and transfers. i'm not trying to be controversial here. just talking my personal preferences.

so a supposed breakthru digital product that ignores dsd is a non starter for me. understand that i have not heard this product myself. it may make PCM sound better than my master tapes; or it may not. but on the face of it a product that merely improves PCM does not get my juices flowing no matter the buzz. i reserve the right to piss my pants if/when i hear it.

the price of the thing is not the issue......it's the actual performance. if i love it then the price does become important.

Mike, what is the issue with PCM, excuse my ignorance? I know you were directed to the Audio Exotics HK forum site for the Dalby weight, and didn't get very far. It's on this site that it appears the selective audiophiles of Honk Kong are going collectively crazy over the Stahl Tek, firstly Vekian, and now Opus. The vast majority are analogue afficionados and feel the Stahl Tek is the only player that has the tonal density and ease of transparency tts like the Da Vinci demonstrate. You'd certainly hope so for upwards of $70000!

Thanks Geoff.

maybe not 2030 for retiring, but not in the next year or two either.

Don't do a "Mikey" on them now. ;-).

i respect that Fremer has alot on his mind and lacks the 'paranoia' of ownership. he has the choice and station in life to be less than fanatically careful. i've lived with the reality of darTZeel circuit purity and relative lack of idiot proofing in the quest for ultimate fidelity for 6+ years with zero issues. i had the big 458's in my room for a month 3 years ago. they are really bullitt proof if a few basic rules are followed.

mainly 2 simple things. (1) always allow the amp to bleed off power for 4-5 minutes after turn off prior to turning back on. (2) no hot plugging or unplugging anything.

and a third for the 458's, remember to use the stabilizing bolts for shipping.

it's not rocket science. but for a harried reviewer i can see the conflict. all these different products and different rules. and i'm not saying this tongue in cheek. i respect that Fremer has lots of details to keep straight.

Marc,

i don't have a problem with you suggesting products. i've not paid attention to the Stahl Tek products, they may set new standards for digital playback. or, even if they are very very good, they more likely might offer a slight incremental improvement over other SOTA digital such as my Playback Designs. my view is that there is not any significant performance difference between the handfull of top level digital players.

i did scan the 6 Moons review briefly and it does sound like it sounds analog which is one reason i enjoy the Playback Designs.....a good sign i suppose.

based on my quick look at the Stahl Tek products, they are PCM only......which for me is a huge stop sign.

at some point if i get a chance to hear the product who knows. it may rock my world. my mind is open.

i do not have a digital itch that i need scratched right now. i'm enjoying the Playback Designs playing dsd off my server dac.....and it's really very good.....for when i'm in the mood for it.

thanks for the heads up. when i do see it i will pay attention.

mikelavigne

Mike, I know you might hate me for my next suggestion (and to think, we've only just met via the internet, ha ha!). You're soon to complete a system to die for - nowhere left to go re improving tt (NVS), arm (Telos), cart (Anna), amps (top of line Darts), spkrs (MM7's), balanced power etc. It seems to me that there will be only one last component to seriously considering upgrading, that being your digital. I know you really rate your PD, but the Stahl Tek Opus cdt/dac REALLY looks the business, built to beyond-Boulder standards bulletproof, and various forum boards really consider it the cat's whiskers.
It seems to really marry the best of uber resolution units like DCS with true to analogue warmth and transparency apparently found in v.few if any other players.
So, if you have any change left over from the Dart monoblocks purchase...

i did just step up and order a pair of darTZeel NHB-458 mono block's and i'm very excited about it. i had to gulp a few times over the dollars and retirement will need to wait a bit longer. not sure how soon i will get them as there is a wait list for them. likely a couple-three months.

when it does get near i'll need to sell the stereo NHB-108.

i am truely looking forward to the MM7/458 combo.

mikelavigne

Mike, I think we are of one mind on this. And the last thing I'm going to do is claim this is the best and only way forward, Peterayer certainly got me to be a little humbler, lol!
But this is a real game changer for me, just as going to speakers with xoverless full range drivers (new Zu Definitions Mk 4s on their way!) have been for some time (Mk2s).
It's amazing that removing (what I believe to be) the dominant belt drive colouration of vinyl replay has led to the greater revealing of all the other positive attributes of analogue, which with a digital like precision, has me really investigating all those old favourites.
The amazing thing is the entry ticket to this rig is the cost of one of your top end interconnects!
What this all means is that I'm now a lot closer to the end of this continual audio merry-go-round: tt/arm/cd/amps/spkrs just about there. Remaining avenues to investigate: cart/phono stage/uprated balanced power/vibration control.
Will post system photos/write up on Forum when Zu spkrs finally arrive in the Autumn, about same time you HAUL the MM7s into your space!

hi Marc,

it's great to see your passion for direct drive and the Trans Fi. and linear tracking done right does give that very solid and spacious soundstage.

as much as i agree with your perspectives on direct drive, i don't see things quite as black and white as you do in respect to belts. the better belt drive tt's can be pretty darm good. DD is just a bit 'gooder' at the top of the food chain.

similarly on linear trackers, they do have advantages over better pivoted arms but not over all of the very best pivoted arms. execution does become dominant ultimately and then i like unipivots as the best of the best.

someday i hope to hear the Trans Fi and Terminator T3 Pro and maybe i'll get that particular sickness too. :-)

mikelavigne

Mike, a quick update on my experiences moving away from belt drive. It is without doubt the most positively surreal experience I've had since starting in high end audio in 1995.
The combination of the positives of digital ie lack of time domain bass 'smear' and image stability, has been combined with all the traditional positives of good analogue ie tonal density, soundstage transparency, micro and macro dynamic integrity, into what is almost a new listening experience beyond anything I've ever heard in top digital, and only hinted at in uber expensive tts at shows.
I would really recommend analogue afficionados to go out and investigate dd/idler/rim drive more fully, whether it's my Trans Fi Salvation, or TTWeights, your NVS, Grand Prix Monaco, Brinkmann Bardo, Dobbins Beat, tricked out Garrards/Lencos/SP10s.
I know for many the paradigm shift won't be palatable, and the euphonic colouration I really believe to be endemic to belt drives will always be a factor many like in their presentation, but the truthful neutrality of non belt drives (some if not all) will really float the boat of at least a sizeable minority.
Additionally, I can't speak highly enough of the groove tracking abilities imparted by the Terminator T3Pro air bearing linear tracking arm. So many times I'm really unaware of coming to the end of an lp side, so stable and uncoloured and spacious is the soundstage as the stylus negotiates those lead out grooves. Spooky!

hi Joe,

thank you for the kind comments. i will admit that while the room looks impressive, it did take 5-6 years in the room for me to learn enough to make changes to finally realize it's potential.

so yes, the bass integration was a challenge. initially my original Kharma speakers could not do enough bass for the room. so i changed speakers. looking back my biggest problem was that the room originally was overdamped with too much bass trapping and absorbant fabric on the walls. eventually with the help of some knowledgable friends, i was able to decifier the problem and made some physical changes to the room itself, and then was able about 2 years ago to get the bass to really integrate right. my Evolution Acoustics MM3's do have adjustable crossovers and other bass adjustments and between the room changes and those adjustments i now do have what i consider excellent bass balance and integration....and a very smooth upper-mid-deep bass transition.

as far as treatments, everything (mostly diffusion) is built in except the RPG Skylines in the center behind the speakers, and the Auralex T-Fusors which are on the side walls and ceiling wells. the Skylines help to get a perfect center image by keeping the first reflections coherent. the T-fusors elimnate slap echo. neither are much concerned with mid or deep bass.

mikelavigne

I am speechless, the room really shows all the hard work and planning you have put into it. If there was a Hall of Fame for audio you be in on the first ballot. Question, was the bass integration hard for you to get right? My personal experience has taught me that even though bass can be clean and tight it is very easy for it to intrude on the midrange and the cleaner it is the harder it is to detect. Did the room treatments solve the integration or did you have to modify the crossover? Or what was it not a problem for you at all? Want to thank you for posting your room is the finest I have seen. Enjoy

Stereotaipei,

sorry for the delay in my response; i have been out of town on business. it is great to hear from you and trust all is well. i did just email you a response to your question.

i understand the MM3's won't fit in your current place. i suppose that means that the MM7's won't fit either.

too bad. :-)

maybe in the new place you are building.

Mike,
I have decided now to sell the MM3 (too much of a mess to store them until my second home is built). May I ask you how much you got for your pair?

hello Andrew,

i did google 'Dalby vinyl stabilizer', 'NVS', and 'Durand' and saw what is likely a Chinese forum, but could not understand what might have been said. i am curious about it. i did read about the stabilizer; looks interesting.

please provide a link here, or email it to me;

Hi Mike, moving away from belt drive/pivoted arms certainly has been an education! Unbelievable clarity and a vibrant, almost live music like presence has been the upside. Downsides have been some unforgiveness with less than stellar material, exacerbated by it's brilliance with music recorded in the analog heyday of the pre-1980's. Additionally, it's highlighting need for careful cart/phono choice, and absolute need for levelling/vibration control.
On the former side, I'm going to dig out my long unused Transfiguration Orpheus, and together with my Zu 103 go down the paratrace profile stylus retipping/upgraded White Sapphire cantilever route, and manage an a-b demo against the Soundsmith Straingauge.
On the latter side, I'm aiming to invest in a Minus K BM-8 isolation shelf for the tt, which is good for controlling vibration down to 0.5 Hz in the horizontal plane, and 1.5 Hz in the lateral, both figures below the threshold of the tt's performance. It's pricey at close on $3000, but should give me close to state of the art isolation for this really sensitive piece of analog equipment.
