Description

This is my music system which has been evolving for over 35 years.

Have had many different components of many styles. Have learned that synergy is everything and you have to trust your ears.

Also I've had had these systems in over a dozen listening rooms. I've spent many hours working on room treatments and setup and believe the room/speaker interaction is the most important aspect of great sound that many hobbyists fail to optimize.

Vinyl is spinning about 80% of the time (Used to be 90% vinyl, but digital changes both sonically and user experience w/Roon & Qobuz have been a big improvement). After relocating to Austin, TX and getting the room optimized, I changed the analog side of the system, having sold tt, arm, carts & phono stage prior to the move. 
Most recent projects have been upgrading from microRendu and Schiit Gungnir Multibit DAC to opticalRendu, SonicTransporter as Roon core, and Denafrips Pontus II. Later I added a number of NOS cables from Tel Wire, something I've wanted to do for more than a decade.

Hey Mike, 
The recording of Fantasia was a gift from the Philadelphia Area Audio Group, when I had to resign as President due to my relocation to Austin, TX. The writing are comments from members for my sendoff. 

Bowie was busted for weed in Rochester, IIRC. Now Snoop has his own brand!

sbank

Hey Spencer, Love the recording of Fantasia poster. I've got to find a copy of it. 
The Turntable is up and running. Pictures of it are posted.
Was that picture of Bowie taken when he got arrested for Cocaine?

Spencer,
Thanks!  I just got Conception a few days ago.  I need to give it another listen.

I'll look for the skyline plans.  I want to add some diffusers above and behind the listening position.  I'm planning a couple silk ficus trees for diffusion behind/between the panels.

I don't have a lot of room to experiment with seating or panel placement.  The nominal room dimensions are 17'6" W x 15' D, but a bay window and coffee bar alcove increase the depth to 24' (really only a factor in exacerbating bass mode complexity).  My primary listening position is at ~1/3 and bass is managed +/- 1 dB with multi subs in that position.  Closer to the wall or center of the room and bass gets really tough to manage due to room modes.

My favorite Tone Poets so far are Lou Donaldson Mr Shingaling, both Stanley Turrentine releases, Katanga, and Witch Doctor (Witch Doctor is pretty hot and distorted on some of the drum solos, but the overall groove more  than makes up for it)

Hi achipo,

My speaker panels are about 5' from the front wall. In another room I previously had them 4.5'. 4' is probably fine. You might want to play around with distance from your seat. I found that moving the seating in 6in. increments forward or back made noticeable differences. 

Yes, my wife and I made the diffusors. They weigh ~18-20lbs. each, and hung easily with picture hanging wire and a 50lb. rated Ook branded picture hanger hook. (Those work great) 
We made them using 1/2" birch plywood as the backer and 2x2" pine for the varying cut pieces. A link to the plans is somewhere in this system thread comments, including the math-based arrangement of the 1"-4" high blocks. It was a fun and easy project! Buy 2" x 8ft. pine, stain it to your preference, cut down a bunch of 1,2,3 & 4in. pieces and then glue them to the backer following the diagram. We mitred a piece of molding to trim the backer edges. 
I'm happy with the coverage as shown in photos. I tried all four diffusors between the speakers, and decided 2 were better than four. This is when used with absorption behind the speakers, both the Owens Corning-based panels and the rockwool-filled bass traps. 

For your Tone poets collection be sure to add Sonny Clark - My Conception; it's a winner with an allstar cast! Cheers,
Spencer

Spencer,


I just looked at your room pics. It gives me great hope that my room will work well for Sound Lab speakers.

A couple questions:
1. About how far are your panels from the back wall? Mine will be about 4' from a paneled wall with broadband absorbers in the bottom and top of built in bookcases and LPs in the middle shelves.
2. Did you make your BBC skyline diffusers? About how much do they weigh? Are you happy with the coverage or would you like more?


PS I totally agree with the Tone Poet recommendation.  They are outstanding records--every single one I've purchased (I'm up to 15 now I think?)

Joni Mitchell - The Reprise Years Box Set
The Bernie Grundman mastered Blue is like a component upgrade vs. my original pressing. Don't forget the goosebumps come from listening to great recordings. Vinyl lovers, drop a Benjamin and get it while you can! 

sbank

Owner
Just wanted to say to all you vinyl lovers, go buy some Tone Poets! Listening to Paul Chambers - Bass On Top, Wow!
Tina Brooks - The Waiting Game, Joe Henderson - Sound of the Tenor Vol1. All are great sounding recordings of great, somewhat lesser known jazz titles. 
Don't wanna stop listening...

Thanks, Jim. 
Yeah, I can get sucked right in when I sit down. Checking out the new Springsteen in 24/96 as I type this ;-).  BTW, best Bruce in decades. Cheers.

Great looking system. Love the Sound Labs. A friend of mine has those and when you sit down to listen, you don't want to get up again.

Haven't posted any updates in quite some time...When relocating to Austin, TX a couple of years ago, I sold my beloved Technics SP-10 setup to a local friend including my vintage cartridges and phono stage, rather than moving it cross-country. After settling in, I bought the newly designed Sota Nova Series VI turntable, and set it up with an Audiomods Series V tonearm with all silver wiring, and a Dynavector XX2 mk2. That's feeding a Nagra BPS battery powered phon stage, which I chose to minimize interference from the grid. It's all working out great.
Just recently I decided to upgrade the digital source. The Sonore microRendu was replaced by Sonore's opticalRendu + Sonore linear power supply and the Schiit Audio Gungnir Multibit was replaced by a Denafrips Pontus. I also subscribed to Roon in lieu of the various DLNA/UPnP apps (e.g. Lumin, Linn Kazoo) that I used for control previously). After only a couple weeks break-in for the new DAC, I am already very pleased with the improvements in both sonics and UX. 
New room photos coming soon...
Comments and questions are welcomed...Cheers,
Spencer

Well, I sold the Lamms. So I guess it's time to rename the system. Any suggestions? Some of my friends call it "The Sound Lab Lab." My wife calls it "The Twin Towers."

sbank

Owner
Hi Chris,
Thanks for your suggestion I will check it out. 
Here's the story on why the change...Many friends have fallen in love with my Sound Labs when they hear them. One told me months ago that he will want to get some someday. His CJ MF2500 came over and we quickly decided that it wasn't up to driving the SLs. He replaced it with a Krell KSA250 partially based on my comments about great combos of Krell KSA and Apogee electrostatics that I've heard many times. He is ready to order SLs and brought the KSA-250 over to confirm the match w/the A3s. Well I knew it would be decent but didn't expect it to be as good as it was. Bass and spacial performance were uncanny. Lamms were superior in top end timbre but it was much closer than I expected. Overall the Krell created lots of goosebumps and positive surprises. I did notice that experimenting w/couple of power cables did make a noticeable difference in smoothness and detail in treble and upper mids. (My Transparent Super was a good match). At less than half the cost of the Lamms, I decided to reduce my investment in the system, and make the change. My take is that FPB series betters the KSAs and are a few years younger. I was fortunate to find one recently recapped and being shipped directly from Krell after a checkup with arrival next week. Cheers,
Spencer

Hi Sbank 
Very nice system. Your SL's are one of the speakers I really wanted to setup in my house to hear but space, time, and wife will just not permit it.   
Regarding your looking for a power cord. I have been dealing with Gene at Take Five Audio in Canada for many years. Not sure if you are familiar with them. Gene just made a 20amp power cord for an audio  friend in New Jersey also with a Krell amp. If you Google Take Five Audio you can get more info them. You would also be getting the 30 per cent dollar exchange difference between our dollars, and I think free shipping but not sure on that one. Just a thought.  
Curious to know why you are going to Krell from the Lamm ? 
Cheers Chris

Just sold my Lamm M2.1 monoblocks and bought a Krell FPB-300 stereo amp which should be arriving in the next week. Looking for a 20amp power cable to use with the Krell.

Added a custom made 4.2kg stainless steel platter mat 8mm tall which besides the benefits of the additional mass allows wider range of VTA adjustment. 
Also awaiting arrival of another cartridge, a vintage Goldbug Clement II mc.

sbank

Spencer, I appreciate the generous offer and will do so should I get over that way.

I heard the big Sound Labs (two pairs set up side by side IIRC) driven by Pass monoblocks in Ray Kimber's room at RMAF a few years ago and it was an experience to remember. Enjoy your fine system.

@shadorne Yes, JGH had the A3s as his reference for many years. One of my favorite writers of all time. Thanks for your kind words.

@dentdog The Aqvox can provide 75db balanced, how much more gain are you going to find elsewhere? If you ever get near Philly, you are welcome to come for a listen. 

Just added pics of my Ultrasonic cleaning setup following inspiration and guidance from @rushton 's great article in Positive Feedback and here. 

sbank

Like that you went balanced throughout. Looked at the Aqvox myself but needed more boost. Never heard Soundless but would love to. No doubt you're having some fun here. Great system!

dentdog

Fantastic system! Aren't these the same speakers Gordon J Holt had for many years?

Added a few Shunyata Research Venom 3 power cables. 

Sold the Technics cartridge that came in a package with my SP10. Spending time tweaking setup of the Signet and Satin cartridges in various headshells.
