What are the weak points of Pass amps and pre-amps ?

Had Pass 350.8 wonderful stage,bass,depth,imaging and powerful full bass didn't see any weak points.

Price. Value.

I have repeatedly been told they are very refined amps. Never heard a pair that made me wamt to take out a mortgage for them.

I have the XP12 and 250.8.

Really like them, the weakness is that because like most of us I like to try new things... but these are the first combo that I've been afraid to sell off and try something else!

So, suppose tempering the fun of research and upgraditis could be a weakness.

I feel the XP12 is really neutral.  I don't think the 250.8 is dead neutral, but it just sounds good with every speaker I've tried with it.

I made an extensive list of all the weak points and shortcomings of Pass pre-amps and amps. Here it is.....this is everything I could come up with.....

By "weak points" I meant more their weaker points compared to their strengths, not something that they do wrong.
I don't believe in absolute neutrality, and I most definitely don't want sterile sound.
ebm. you now have Audia Flight amps, how do they compare, what are the differences ?
Pass Labs is not the uppermost high end, as I understand, speaking of a wish to have them at any cost. As for value, they in fact do appear to be an excellent value. Not engaging enough ? Not much to write home about ? Just excellent amps ?
