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

As usual Troy, you hijacked a thread to push your wares.

I like meters also.  Just think that new coda looks like tic tac toe board.  I’m sure it sounds great. I’ve stated that elsewhere. 

Hell I’ve talked to Doug, he’s a good guy.  He thinks meters are useless, but knows the market likes them.  

I answered the OPs original question.  You hijacked a thread again.

Yes, T+A and Coda make nice products.  I’ve owned Coda and demoed T+A.

I mentioned the heat and weight, as I was answering the question. 

So, so far no real weak points, just a few minor weaker points.
But no-one described Pass Class A and Class AB differences in details yet. Anyway, one can get Pass pre/power amps used for $5k-$6k for both. Pretty good.

The meters on Pass amps don't have much choice except to reflect what the amp is doing. They measure the bias current draw which is why they hardly do anything. 

Inna, currently I have pass int-250 (again). Before that I had many integrated including bryston, plinius hiato, gamut 150le, pass int-60, gryphon diablo 300, luxman 509x. I had to sell gryphon diablo for financial reasons. In my system with my speakers (Sonus Faber Amati tradition) gryphon and pass-int-250 were the best. Initially I though pass is lacking dynamics, until I found cables and power conditioner that made it sound more dynamic and more explosive. The top end also became great - again proper speaker cables needed to extract everything that pass can provide. Gryphon 300 was better with dynamic swings and articulation but not much. Pass has bigger 3d sounstage. Weekness - some air between players is not as good as dagostino and gryphon.  Read Audiodorm review on pass int-250 were they give 92 points to this integrated and prefer it over accuphase 650 and luxman 509x. There is another reason I decided to get pass again - service and US made product.
