Integrated amp -- Pass Labs vs Luxman vs McIntosh


I posted a similar query earlier but did not get a lot of responses unfortunately. As mentioned before, my speakers are Sonus Faber Olympica II, currently driven by Rogue Audio Cronus Magnum II, in a 20x15 dedicated media room. As an aside, I’m already working with GIK acoustics to treat the room. As much as I love the Cronus Magnum II, it’s clearly struggling with the speakers and room dimensions. I have been doing some research and narrowed my choices to the following (Note: mostly looking for used since my budget is $5 - 6k max)

Pass Labs INT-60 -- love the fact that the first 30 watts are all Class A; these don’t come up for sale often though. I’ve heard that these are as close to the tube sound one can get without compromising what makes SS great. I listened to INT-150 a couple of years ago and was really impressed. From what I’ve read, the 60s are clearly a step up in every way. Besides, I’ve always been fascinated by Pass Labs.

Luxman 590AXII -- I have yet to read anything negative about these. I like the fact that they are a class A design. Unfortunately, the only Luxmans I’ve listened to were 20+ years old and did not leave much of an impression (polite to a fault).

McIntosh MA352 -- A friend has the smaller brother, MA252, which I really like but not sure if they have enough juice to drive my speakers. None of the dealers near me carry the MA352 so I have to rely on feedback alone. I like the fact that this is a hybrid.

Another suggestion from a dealer is Naim SuperNait 3, but honestly I don’t know if it competes in the same playground as the aforementioned amps.

My goal is to find a nice balance between the strengths of tubes and SS -- retain good 3D soundstage, instrument separation, midrange magic, but not at the expense of bass and dynamics. I do understand that I cannot expect an SS, regardless of class A or not, to have the same lush, holographic presentation of tube amps, but want something that gets as close as possible.

I would love to listen from owners or people who have heard the amps before. Since I’m buying used, I will not have the opportunity to return them so due diligence is necessary.

OP - what do you hear/mean when you say that the Magnum is 'clearly struggling with the speakers and room dimensions'?

Going the opposite way with power with your short list seems counter productive.
Audio research Gsi75 integrated is superb, but not cheap. It was about 16k new, now can probably get for around 10k. 

I second Luxman, they're amazing amps. Id take the Luxman 590AXII over pass, and definitely over MAC. I own Mac system as well, it sounds great with SF, but way too romantic and lush. 

I'd still recommend tubes with SF. Audio research Ref 75 is superb, but you'd need a preamp. You can get this amp for about 4-5k used and get a decent tube preamp for around 1-2k. Tubes make SF sound absolutely sublime. Once you hear tubes, its hard going back to SS. 
i would suggest what you are really looking for is a big hegel -- if it is indeed the sound that matters... h360 h390 or h590

If you buy a Coda directly from Coda,  they will bias the amp differently if requested.  It comes in 3 versions, v1 is 400 watts per channel, v2 is 250 watts per channel and v3 is 150 watts per channel.  It is all the same amp, the difference is how the amp is biased to produce more class A output.
