A few years ago I bought a pre-owned Pass INT-150. I replaced a Wyred4sound 4 channel amplifier, because I no longer needed to bi-amp. Talk about going from apples to oranges... The Pass was kind of an impulse buy. I did not compare to anything else at the time. I can't really come up with any weak points other than that yes, they do run very warm. That is intentional though. I don't plan on changing unless some other system change forces me to. I can envision a scenario where an integrated would not be appropriate, but for my system now, I prefer the convenience and the sound synergy of the Pass integrated.
