Pass Labs AMP’s- What is the best Pass Amp Sound for You from past 10 years

"[...Interesting the int 250 doesn't get much love here. The reviews are pretty darn good....]" Report
I have noticed that. Although the reviews and forum comments have been highly enthusiastic, positive, and consistently so. Perhaps it's because most of the Pass Labs amps that we read about have been around much longer than the int 250. The int 250 is still a relatively recent design and has not been around long enough to have developed the fan base that the older Pass amps have. Also, the int 250 is a pricey amp and that can somewhat restrict sales. It'll just take time for the int 250 to populate. And it looks like I might soon be adding to that population.

Looks like I was wrong. Pass gear is getting plenty of love here lately.

Great thread and views. New to (higher end) hi-fi by recently getting Sonus Faber Olympica III speakers and am now looking for a Pass Labs amplifier.
Any advice on which of the Pass amps - integrated or separates, would work well with these speakers? The room is large with a high ceiling. Mostly listen to jazz, blues, classical music. 
Cheers.

I have had the following Pass amps in the last few years:  XA-25, XA-30.8, and INT-60.  The 30.8 was best, second was the INT-60.  The worst by far was the XA-25.  It was impressive for great recordings when listening for shorter periods, but with less than stellar recordings or longer listening sessions, it was fatiguing.  I even added a tube preamp to no avail.  It perhaps was too transparent.  I just did not like it much.

Happy Pi Day;
I have had a few Pass amps over the years; X250.5 (circa 2007), X150.8, X250.8, XA30.5, and now INT-250; My system has been in mega churn last half of 2019, but has quieted down recently; I took a tour with some Luxman stuff, the 507Ui, 509X, and the 900 models, the M-900/C-900 combo. I let go of the 900 stuff late last year and ordered an INT-250; I have been LOVING the INT-250 and feel, for me, its just perfect....but...I moved up to a larger set of speakers, the Dynaudio Confidence 50s and have been talking to Pass about next steps-very interested in the X260.8 monos, X350.8, or perhaps XA100.8 (not a huge fan of two giant power sucking Class A monos but they probably offer best sound quality) .

I came across a chance to get back into the C-900 preamp, which to me is just phenomenal; The M-900, yes is very good, but I feel there is a better match between amp/speakers with Pass horsepower. The sound is super neutral and has a natural feel across the board with Pass/Dyn;
So, i’m currently using a Chord TT2 into the C-900, into the XLR input on the INT-250 and the SQ is far beyond what I had with just the TT2 into the Pass;
So I have an ad on USAM for the INT-250 (bought brand new at RENO) hoping to get the 260.8’s;

I loved my time with the XA-30.5; it was just pure sweet magic to my ears. The best most dimensional presentation of voices i’ve yet to hear--just very intoxicating. However the bass could be a bit flabby at times and at higher levels into the Dyns I could hear it strain a tad--but that was super loud. I remain amazed at how few watts are actually required on an RMS basis.

Overall the newer 0.8 series has superb upper treble refinement and is still highly resolving; The midrange is neutral and voices sound real to me; I think the 0.8 series overall have a cleaner and clearer presentation than the 0.5 predecessors; But, speaker matching and room response will be the final arbiter on overall "tone";

I recently installed a bunch of GIK bass traps and after some frustration (they are very effective and little goes a long way) settled onto a configuration that works; With this I have discovered new levels of bass tone and definition--they were always there but the "Lens" (aka room response) was foggy;

I have learned that much of my judgement on equipment and speakers was muddled and incomplete because of ill-controlled room acoustics. I strongly believe we rip through gear looking for subtle synergies, but the real cause of frustration with the sonic result (why else do we go through equipment churn?) is from a confounding room response.

Back to the OP's question: I don't have a favorite I suppose; they all have positive attributes in their own way that the rest of the system pieces flush out or suppress; I kind of wish I had a rack in some back closet that could store them all, lol;

Sorry for long and meandering response, just feel like writing to get my mind off the current events.

Happy Listening All and Keep Clean!
