questions for georgehifi and others about powering my Wilson Sasha2s

Conversation with georgehifiArchive this

George, I read a thread you commented on about amps for Sasha 2s, but the direction got derailed when Troy came in and it deteriorated into the merits of Troy providing insights rather than the content of the insights.  I have seen other posts by you and I respect what you have said. I have been flailing around with my system the last two years. I've been doing my best to ferret out gear that makes sense, and I have made great progress, but its been messy. Synergy though reading reviews is elusive!! I ended up recently with Sasha 2s, sourced only by a Vivaldi Stack, Modwright LS300 (had to get tubes to tame the dCS and Sasha 2 combo) and JC1+ amps, Everest with all Shunyata Sigma V2 and V1 and Alpha V2 power cords. Some gear sits on Townshend platforms, Sashas on Podiums, and IC and SC loom is Townshend F1s. My Sasha 2 amp journey started with the amp I had which was a Naim DR300 NAP which was not very detailed and not powerful enough for the sasha 2s, but a fun amp on my old B and W 801s. I then bought the JC1+s and was very impressed. Wife finally loved the sound of my system again. I did think the JC1+ lacked a bit of resolution, but it was a sweet and powerful sound with a strong lower foundation that was a joy in musical terms to listen to. I then got weak and started to give in to the dogging on the JC1+s that is quite easy to come across.  Last Friday I took delivery of a NIB Luxman m900u. Figuring if it was as musical as everyone claimed I'd buy a second one and be done with my amp search. It's been burning in for about 100 hours now. It's got more resolution, and a deeper soundstage, and while it's bass is musical it's bass light. The real problem is that in my system its too bright on female vocals, strings and piano. Wife wants the JC1+s back but I've heard that resolution and depth and I can't unhear it. Guys a know on line now say its a bad match for Sasha 2s, two guys say I need Ampzilla 2000 V2s, some say Modwright KSE 150, others say the Modwright or two are not good enough. I have avoided tube amps my whole life, but? My budget is around 22K for amps, so two used m900us were perfect. Do you think the Luxman will burn in/burn burn/off the brightness? I am over using cables as tuning devices, but It did occur to me to roll the 7308 Amperex USN in the LS300 for some British warm tubes to compensate. Can you shed any light on my situation? I'm pretty beat up and disappointed right now. Often on this forum I hear about all these product recommendations for products and companies I have never heard of. I don't want Macintosh like brands but also not any  tiny start ups that are not even fully rolled out. Thanks for any help.

Wow, you just nailed it! I am smitten with parts of the Luxman, but the match with the Wilsons is not what I want. Yes, the Wilsons in my room need a warm support system. I really appreciate you taking the time to share your experience, as I am confident in what I hear, but it didn't jibe with what I read on line about the m900u "sound". Thanks for your insight!
I had an ARC Ref 6 but moved to a Boulder 2110 preamp. It wasn’t close. The Boulder is in a totally different league. Even the 1110. The ARC is good, but I felt like it didn’t have the resolution that the Wilson are capable of. Btw, I am using a dCS Rossini for digital. I couldn’t be happier with the dCS/Boulder/Boulder/Wilson setup. 
Yes, the general comments about the M900u are justifiably positive in so many ways.  But when people talk about "warmer" with it, I think they are just reacting to its midrange, not really addressing its bass foundation.  When I posted about it not gelling with my TAD's I did get a few acknowledgements that it isn't exactly a robust bass amp.  It's a great amp if matched with the right speakers, I would heartily believe.  I just didn't experience that match.
You have the perfect front end and the perfect speakers.  Wilson Audio speakers sound better using their own crossover than biamped.  Wilson speakers sound amazing with Dan D'Agostino amps.  There aren't many amplifiers that can resolve what a dCS Vivaldi stack puts out.

Wilson speakers sound amazing with Dan D’Agostino amps

It was once said, I "think" by John Atkinson, Wilson in the early days voiced their speakers with big ARC tubes, but in the last 15 years they’ve been voicing them with D’Agostino designed amps Krell and then D’Ago’s own when he left Krell.
That’s why when I hear my friends Alexia and another last model Watt/ Puppy "8"? They both sound stunning wi the Gryphon’s as they are in the same vain as the Krell’s and D’Ago, wattage doublers right down to 2ohms except I believe even the big Gryphon’s even better, as they have even more fixed bias Class-A.

Cheers George
