This is the first time I’ve heard Pass Labs amps being described as thin and really that is the furthest from my experience with them. So I guess it all comes down to system particulars.
I like Ayre as well but would say that compared to Pass, they are leaner sounding - at least the non Twenty versions are.
I came close to buying some MX R’s (non Twenty) but ended up with Pass which had a more ballsy and definitely fuller sound. Thin they are definitely not. I've heard the X250.5 and would not describe them as thin either - granted the top end has a bit of grain. The Ayre’s were smooth and rolled off up top in a good way and I would have been happy with them too.
