Recommendation for a highly resolving amp


I have Don Sachs 2 tube preamp driving Pass Labs X350.5 driving Sound Lab M545 ESL speakers. I like the sound very much, but when I went to hear my friend’s Spectral system (driving Quad2912 ESL) I realized my system can benefit from having a higher resolution amp. Spectral amps need all Spectral preamp/cabling, which would be quite expensive. What would you recommend?

@phcollie.    Have you compared Bryston cubed to other amps?

@mboldda1.  My friend is reluctant to move his amp as it is >60 lbs.
When I tried fiber optic, it sounded a bit harsh and I didn't like the sonic character. I do have room treatments, behind the speakers and on side walls.
I have tried fiber optic and other top 6SN7 tubes. Not big difference. By resolving, I mean high resolution, clarity, detail.

What do people think about the Bryston cube series? Specs are similar to Spectral amps.
My friends room is significantly larger than mine, so the comparison is really apples and oranges. I can't do anything about the tiny size of my room. Since I do not own a Roon, I don't know how to get the room analyzed. I am using Audiosensibility cables, which are considered one of the best reasonably priced cables.

I am also realizing that the needle never even goes close to the midline, which marks the class A limit of 40W. So, even though ESL are considered power hungry and my M545 is 86db, I think I could get by with around 100 W.
I will certainly consider the room treatment. Mean while, I want to go back to the amp question.

@yyzsantabarbara, are you talking about Simaudio 860 or V2? How do they compare with W8?
@edilita, Unfortunately friend's Spectral amp only works with a Spectral preamp.

@jdjohn, Don Sachs does not have XLR, I could get the RCA-XLR cable from Benchmark. How do you like AHB2?
My friend is a Spectral man, so he recommends a complete Spectral system. Along with all the MIT cables.
@yyzsantabarbara,  X1 is directly connected to the ethernet/modem. X1 does not take wifi. Looking back, I don't think I was very clear with my intent. As many of you mentioned Pass/Don Sach are very high quality instruments and I agree. In fact it sounds VERY good-as good as my local dealer's set up with ARC Ref 6/ARC Ref 160S. But, I still feel I can better hear the "peach fuzz" and realism in music with my friend's system.
What you are saying is true. However, what I learned from his system is what it sounds like when there is higher resolution. I am not necessarily trying to recreate his sound; just better sound for my system.
@atmasphere,

My friend uses his Spectrals to drive Quad ESLs and it sounds great. Would Soundlab ESL be that different than Quad?

@jdane, by resolution I mean clarity and realism. Like ultra high definition TV vs regular HD TV.
I will be receiving Benchmark AHB2 amps in 1-2 weeks and do a comparison with X350.5. I have to say, the X350.5 sound is gorgeous and luscious.

Yes, I am aware that Pass and AHB2 at the opposite ends of the spectrum in sound. I do like luscious sound but I also like amps with high detail. I enjoyed listening to my friends Spectral amp, which I am assuming would sound more like AHB2. When I was listening to Louis Armstrong sing, it sound like he was in my listening room. What has your experience with AHB2 been like?
I was also thinking about Coda 16. It is hard to imagine 100W class A has the same detail as AHB2. It seems like Coda is not a well known company.
One strategy to get detail with sweetness may be to combine a tube pre with AHB2. Has anyone tried this?
