Pass labs krell parasound amps

Pass Labs amps are incredibly reliable ( I have owned 4 the past 20 years), including the great sounding X250.8 .... they also offer great customer service - typically you will speak with a very knowledgeable person within a minute or two...

Pass gear has a natural, warm and laid back sound. You can listen to your system for hours without any fatigue. Soundstage is big but accurate.
Nothing is without compromise and Pass is no exception. It’s not going to have the surgical precision, separation, bite and dynamics. It’s not analytical. It’s going to make even less than perfectly recorded music very palatable and enjoyable.

It’s been a while since I heard a Krell amp so I won’t even assume what that particular amp sounds like.

However, one amplifier you should add to your list is Coda No.8. It has the warmth of Class A but is a more articulate and accurate than Pass without being fatiguing. It will also cost less than the X250.8

You can’t go wrong with either Coda or Pass. And yes customer support is excellent with both (Krell is not in a steady state yet after the passing of the owner).

I would not consider McIntosh - just personal preference as to me both Pass and Coda sound superior.

I’ve had Parasound A21, Krell 250s, and now have a Pass XA30.5. Different speakers for all 3 so grain of salt. The 30.5 is the most satisfying amp I’ve owned. Krell and Parasound were both also really good but the Pass is just so liquid but still very dynamic! Ever get that screech from your speakers that’s piercing and hurts your ears? It’s like the Pass is incapable of doing that for me with these speakers. 

Coming recently from a Benchmark AHB2 with the same speakers that did that “screech” very often.
