Description

This is a weird system.

I'm a tube guy, you see; but seven years ago the winds of circumstance blew into my room a pair of 1993 B&W Matrix 800s.  So I'm enjoying a (quixotic?) journey to make them sing with valves.  They're designed to mate with big solid-state iron, but surprisingly are 93 dB efficient and drop to 3.4 ohms at lowest.  

I took care of the bottom octave-and-a-half with a pair of REL 212/SE.  They are amazing.  Then with the low end a solved problem, we made our first amp upgrade in a decade:  The Ayon Spirit III Mk 4, a KT150-based push-pull with 65 watts a side.  It's settling in nicely.

I'm delighted with my DAC, a PS Audio Directstream with ethernet rendering from an internal Bridge II. Recent upgrade of its power cord, to an Audioquest Tornado, underscored the importance of source; it was a two-second, no-question improvement.  You can't *improve* the signal downstream from your source -- you can only hope not to muck it up.

Roon on an iPad ties the whole thing together and sends me down a rabbit-hole of discovery nearly every time I sit down.

Comments and suggestions are welcome.

Components Toggle details

    • Bowers and Wilkins Matrix 800
    Perhaps the finest speaker that could be bought with money in 1992.  (My friend reminds me that you can drive a Honda Civic off the lot today which will smoke a 1992 Lamborghini.)
    • Ayon Audio Spirit III Integrated Class A
    65 watts per side in Pentode mode.  KT150 power section.  Zero negative feedback.
    • REL Acoustics 212SE
    Precision and power.  I use a high-level connection from the amp, and dial the crossover and volume low enough that you can't locate the subs with your ears.
    • PS Audio DirectStream DAC with Bridge II
    This thing is stunningly good for the money.
    • PS Audio Power Plant Premier
    It doesn't have the current to feed an amp, but on source components it's a no-brainer night-and-day improvement.  No problems with this unit for nine years now.
    • MIT Cables Oracle v2.1 spk
    From 2003, custom-terminated at the factory for bi-wiring the 800s.
    • AudioQuest Tornado Source
    From regenerator to DAC.
    • AudioQuest Thunder Power Cord
    From wall to amp.
    • AudioQuest Water XLR interconnect
    From DAC to amp.
    • Pangea Power Cords AC-9
    AC-9s from wall to Power Plant Premier and from wall to subwoofers.
    • Small Green Computer Sonicorbiter SE
    i5 NUC runs Roon Core server in a separate room.
    • Blue Jeans Cable Ethernet Cable, Cat 6a
    This cable blew away the MonoPrice Cat 6a it replaced.  Highly, highly recommended.
    • Boltz Custom
    Not the last word in isolation, but I let the wife pick this one for aesthetics. The glass shelves rest on DIY norsorene half-globes from a scientific supply company.
    • DIY Absorption Panels
    Three hand-wrapped panels of 2"-thick Owens-Corning 703 fiberglass.  They're positioned to kill the first-reflection points on the right wall for the right and left speakers, as well as tame some echo behind the left speaker.
    • GIK Acoustics CT Alpha Series Corner Bass Trap
    In rear corners.
    • PorterPorts AC Outlets
    Another product that hits my sweet spot for price to performance.
    • Melody (Onix) SP-3
    My first hifi purchase, a $500 find on Craigslist!  38-watt push-pull. Tubed with Russian NOS 6P3S-E's in lieu of 5881s. I shall never part with it.

Also, congratulations on having your system be featured on the Audiophile Daily Show,...did see that some weeks ago and he chose a great system to show off!

@cymbop   I had the good fortune to be able to hear Russ' system finally after all the months of delay due to COVID-19, with his new Ayon integrated amp and another update to the software in his DAC.  I'd heard the system right before all the shelter at home and unpleasantness fo the last 1+ years with the new subs and it was a great system however this time around it had attained a whole new level of musicality, imaging and top to bottom coherency. Everything has come together, in a word, perfectly for Russ with his system and it was another incredible time listening to great music and marvelling at how great that system and room together as a music-making machine.

Thanks Russ! Sorry it took me awhile to post this; I've been off Agon for quite a while. 

Well done on the system upgrades....I look forward to having even more time to cut from the day to listen to music, great food and great conversation!

Russ's system is one of the most enjoyable and musically gratifying systems I have ever heard.  Music is at the center of life in that home and he and his wife are such wonderful people to know who truly appreciate great music.

Thank you Russ for my prior visits,...I cannot wait to hear what the addition of the Ayon has done!!!

Russ,...thank you very much for hosting again yesterday! Your system has come a long way over and above how much fun it already was to listen to more than six months ago, much more musical, organic and compelling to listen to, not just in the sweet spot, but around the house.  Your dogs are also just way too cool,...when the jazz starts, they show up in the listening room and want in on the fun!   See you over here very soon,...thank you for a great session!!!

Cymbop: Thank you for opening your beautiful home and system and hosting a great listening session last evening. I loved the simple elegance of the system, how it was set up, the care taken to do so and the way it sounds both musically and with regards to 'in the room' effect and imaging. The tracks played were also alot of fun and great music to boot! The dogs are great listening partners and they made the experience complete! I look forward to reciprocating very soon and then repeating the cycle with more recordings to be shared. Thank you!!!

Tboooe: It's great to see you back in the hobby(!),....I'll leave some comments on your new systems thread.

Thanks for getting in touch with me on the SC area thread that I started up recently...you have one elegant and well thought out system; you must be very happy with how it sounds. How do you like the Zu's and the Audio Arts cables? You are truly fortunate to have a pair of the Matrix 800s to dive into for any period of time; they have always impressed as a speaker whose design and sound stands the test of time. Love the Buddha as well!
