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;

Hi Mike, Congratulation on the Troy Signature. I have the original Troy with the stock ground cables. Pure realism is the best way to describe Troy. Last month I pick-up a Tripoint Orion AC power conditioner and Miguel told me to plug the Troy and the transport to same outlet in the Orion. After 2 days of settle down I am at a lost of words to describe what I am now hearing. The combination of the Troy and Orion gave my system realism, greater transparency,clarity, more details, increased speed, tighter bass and bigger soundstage. Like you I just want to sit back and enjoy the music.

thanks Andrew.

the new year is an especially busy time at work for me and exhausting. I've been listening intently but I've had little energy for anything else.

I did make a few adjustments and additions to my grounding connections. first off; I moved my dart pre power supply/charger so I could plug the darTZeel preamp power supply/charger to the same outlet as the Thor power cord from the Troy. Miguel recommended that as significant; although he did not know if it would be as significant since the dart is battery powered. I did ground the stainless steel arm board.....along with the power supply of the tt as I previously mentioned. I also grounded the outboard LPS of the server.

I've been listening in this way for the last 10 days and it's been sounding great and staying about the same......until.....yesterday afternoon. when I returned back to listening after watching some football (the Seahawks game about killed me) something kicked in and things improved almost as much as the original jump. maybe another 75% of what the original step was.

 I was really impressed with this large step.....blown away might be a good descriptor. this big next step was 11 days after install as a data point.

the soundstage increased noticeably, noise lowered, dynamics increased; but that does not really relate what happened. it's more that the music became more real and organic in the soundstage, the reality quotient increased by a few orders of magnitude. how do you exactly describe that? I don't know. a magical experience. profound. the music is more nuanced, greater ease and greater musical tension at the same time, more holographic, much less processed and less sense of the reproduction chain. like multiple pieces of gear all improved and became more synergistic.

I'm impressed and just want to listen and not think about it.

Hi Mike.  Paul from TRL told me Winston's health was failing.  Very sad.  He is as they say a true "scholar and a gentleman."  What a loss that will be.

Congrats on the Troy.  I knew your uber system/room would clearly reveal its benefits.

i did not notice the external shots of your barn before.  What a stunning location for a listening room!

started listening to the Troy Signature around 8 pm last night. listened till 11pm last night, then today since early.

I have the Thor Reference grounding cable connected to the phono ground post on my dart pre, and a standard silver grounding cable connected to the Tara Grandmaster grounding system on the Golden Gate. the Thor power cable is currently plugged into it's own dedicated outlet (Furutech GTX-D (R) -> Equi=tech).

a place to start.

from the first note this is awesome. it's a whole new ballgame, anything but subtle, and I'm still getting my brain around trying to define the ways it makes the sound better, and the music more real. for now I just want to experience it and enjoy what I'm hearing. and try not to analyze it. but my brain is reacting to new information and new degrees of realism in every recording.

lower noise; yes. more dynamic; yes. better flow and timing; yes. but more than that it seems to supercharge the musical energy.

I just grounded the power supply of the NVS tt. I need to go to the hardware store and find a small screw so I can ground the stainless steel arm board of the tone arm.

I'm very impressed.

Andrew,

again.....sorry for the long delay in my response.....

[quote]Have you ever heard Winston Ma's room. That is a fairly serious affair as well....[/quote]

Winston is a friend, and before i moved to my current home, i lived about 2 miles from his home. I've been to his room quite a few times; although not for quite a few years now. he did visit my old room occasionally, and my new room a few times too. Winston's room is very special. and, of course, it always sounded great when i was there. sadly; Winston is now in failing health. he is one of the great gentleman of our hobby.

[quote]Mike, are you still getting a Tripoint Troy? I am going to get one soon....:)[/quote]

finally yes. my Tripoint Troy SE Signature with Thor power cable and Thor SE Master Reference 1.5m ground cable has shipped to me. it should arrive next week or the following week depending on the shipping.

Stickman,

I apologize for being away from my system page for so long and not answering your questions. so in case you still have an interest....

the front chambers are larger; but that is not any sort of acoustic design imperative. it's just the result of how large the center chamber ended up....and then the longer speaker end relative to the listening end. and the listening position location.

since I took those pictures I have added more fabric treatments to the drop soffits in the middle and rear and that did help. i need to update my pictures.

as far as the hardwood floor; the idea is to mimic a concert hall. so the front hardwood is the stage and it's designed to retain as much energy as possible. the rear seating area mimics the concert hall seating and is somewhat absorptive. i do like the look of hardwood everywhere and add throw carpets. but acoustically the rear wall to wall carpet is better. it's all about acoustic energy balance. 


mikelavigne

Mike,

from your room photos it appears that the two middle soffits with the hanging diffusors are actually longer than the front two and two rear? Is that correct? Your thoughts above make sense; I don't want to design the soffit size and spacing such that the Magnepans end up firing directly into the leading edge of the front of the partition. I'm thinking that the speakers should sit just about flush to the ends of the first soffits on the speaker end. The middle soffit section would be around 1.3 - 1.5 times as long as the front. The back two soffits would be the same length as the front two.

Did you ever consider using hardwood on the entire floor?

thx

stickman451

Yes, yes Charles. You are right. I read this crap late at night. Mike, have you heard Ma's room?

agear

Actually it is Stickman451 building the custom home/dedicated room in Colorado.

charles1dad

Mike, what will you do differently in your CO home? Who is going to run point on the design?

Have you ever heard Winston Ma's room. That is a fairly serious affair as well....

agear

hello Stickman,

thank you for the kind words.

congrats on you and your wife retiring (i'm 2 or 3 years away myself), and then building a custom home in Colorado. and.....the new room project. if you have already had 2 dedicated rooms then you already have a pretty good idea on where you are going. your room dimensions are quite similar to mine, which I can tell you, it is nice to have a little elbow room.....it does allow the music to breathe.

personally I do like the ceiling soffit approach and the angled hanging diffusers. they retain energy but eliminate slap echo. and the soffits break up pressure points along the ceiling. I would only caution you to be careful not to allow a drop soffit between the listening position and the anticipated speaker location. until I recognized cause and effect and treated it with fabric the reflection from that soffit created a 'bright hash' which masked lots of detail.

OTOH your Maggie 20.7's are dipoles and project sound forward and back and not much to sides and up or down. so your room treatments need to deal with that reality, of which I have zero experience. I would recommend that whatever you end up doing to optimize those particular speakers that it be a 'fluid' solution so if you ever end up going to a dynamic cone speaker system that you can easily adjust the treatments.

I am absolutely thrilled with the hardwood floors on the speaker end of my room and think it's the right way to go with a larger room size we both have. you want to retain energy (like those angled diffusors on the ceiling). you can always play around with a small throw rug to experiment with some absorption on that hardwood....in my case whenever I have it deadened the sound and I removed it. smaller rooms need absorption to deal with high SPL's.....different rules apply to different size rooms.

those 20.7's are world class speakers and in a room that size are going to really sing. best wishes with your project and let me know if you have any other questions.

best regards,

mikelavigne

Mike,

I have read about and studied your room design for many years. Now I am finally in a position to build my next (third and final) dedicated room in a new home that will be started early next year! Your room looks phenomenal !!! My wife and I are retiring and moving to a custom built home in Castle Rock, CO.

The new room dimensions will be, 18'-10" w x 29' L x 11'-2". I will use a soffit system very similar to your build. The soffit will be at 10' high and the six trays will go on up to 11'-2". Initially I will install the 22.5 degree hanging diffusors above the listening seat in the center two trays. I haven't worked-out the width of the soffit grid but I will use it to hold my lighting and the HVAC.

I have two questions that I am hoping you can comment on. (1) Have you been happy with the hardwood floor in the speaker end and carpet in the other two thirds of the room? (2) I assume that you are happy using the soffit system. Would you do them exactly the same way again? In your opinion, how wide do they need to be and should all the soffit be the same width (soffit around the room perimeter the same as the cross members)?

My speakers are the new Magnepan 20.7's. I am using the Carver 305 Black Beauty mono-blocks to Great effect on the Maggies! The Black Beauty's use six KT-120's per side and put out a strong 350 Watts into the 4-ohm 20.7's.

Any advice that you could give to me would be greatly appreciated! Thanks.

stickman451

Hi Mike,

Thanks for the link and response in detail. I imagine your listening space and hardware changes result in greater enjoyment. I'm contemplating a Pass XVR-1 as a xover for our Dali.

Our noble pursuit and journey continue!

Sonny and I are enjoying our summer. Got one of our A820's back from Charlie Bolois and found some tubes we like for our Atma-Sphere gear. Good thing we have central AC. :-)

hi Sam,

all is well, and I hope You and Sunny are having a great summer.

Evolution Acoustics Loudspeaker specs

here is my understanding of how this crossover relates to the two different model speakers.

the crossovers in the MM7's is essentially identical to the ones in the 'Exact' column upgrade for the MM2/MM3. however; since the driver compliment is quite different in the MM7's the implementation and values are different.

the MM2/MM3 has a mid range that extends down to approximately 80-120 hz depending on the adjustable setting on the subwoofer, whereas on the MM7's the mid range only goes to 250hz to 300hz range and the -4- 11" woofers per side then do the 30hz to 250hz range. so the components of the crossover are the same, but it has another step. of course, the MM7 then has a whole additional tower for the below 40hz range.

the Exact upgrade does take the MM2/MM3 to another level in terms of detail and transparency and is a desirable and worthwhile upgrade. the MM7's are a whole different thing.

mikelavigne

Hi Mike!

Are the xovers on your MM7's like the xovers on the EA loudspeakers we heard at Newport?

Hope all is well with you and family. :-)

honestly I don't know. I've not spoken to or had contact with Miguel for 6 months and never posted about it anywhere.

I've never heard any Tripoint product but certainly respect it and am curious about what it does like many others.

you apparently know more about it than I do....am I getting a Tripoint Troy?

Miguel mentioned it....are you not?

Agear,

congrats on the Troy.

what makes you think I'm getting one or intended to do that?

update; another step forward.

read this post for context for what I'm describing below.

there are 4 different dials to adjust on each of the 4 separate bass adjustment panels (2 per side) on the bass towers. the OP describes what happened when I adjusted 2 of them for each section; the 'bass level' and the 'bass quality'. I set those to what the designer called 'flat' positions which were quite different (about 40-50% around the adjustment scale) than where they had been in the 'compensated' positions.

we had left the other 2 adjustments (bass filter and bass extension) in the 'compensated' position in case we found that the changes I made did not work, so we did not need to find those positions again.

yesterday I had left a message for the speaker designer asking him if I could also move the other 2 adjustments to the spots he had designated as 'flat' since we did know that we had a positive result from moving the other 2. early last night I had not yet heard back from him and decided 'what the heck' I want to know what that will do, so I did make those adjustments. in this case; both the 'bass filter', which is a variable crossover, and 'bass extension' the 'compensated' positions were much closer to the 'flat' positions. in one of the 4 was already in the 'flat' position.

WHOA! more meat on the bones, more heft in the bass, but it was the fire and sparkle of the mid range that took a significant improvement. vocals were quite a bit better. I had thought I was all the way there on perfect balance of voice and string tone but I was wrong. richer, more harmonic shading, more tube like breath of life.

every reference I have was improved in subtle ways. delicate little things in the soundstage are all more real and filled out and complete. magical.

these were tiny adjustments on 2 innocent dials on the back of some active bass towers that crossover at around 35hz with the main towers. how can this do that? don't know, but they did.
