Bryston 7B Vs. Krell KAV250a


I need help in picking out a better amp between the Bryston 7B and the Krell KAV250a.

A pair of mono block Bryston 7B's at 500W/channel
Krell KAV-250a at 250W/channel

Thanks in advance.

OOoops. Let me retract those coments towards "Pbb"..they were supposed to be to Dave1117, who refered to the "advertising" issues
I Own The Krell KAV250a . I own a few different amps .Adcom . B&K and Anthem .
The Adcom 555 / 555II blows the Krell away . If you're into detail and imaging the Adcom is by far better than the Krell even though it's roughly a third of the price .Just because something is expensive doesn't mean it's better .
The Krell may have a slight edge in bass detail , but very slight . Don't listen to the negative hype about Adcom .Adcom makes a tight ballsy affordable amp .
When I first hooked up the Krell I could not believe the detail lost when compared to the Adcom . Don't get me wrong , The Krell is a nice smooth sounding amp , but if you're looking for detail/imaging check out any Adcom 200wpc amp ..you will hear a stark difference .
I prefer the Krell sonically over the 7B. I currently own 2 KAV 250a/3 and a pair of MDA 500's.
However there are some (even if not sonic) neat advantages to Bryston. The cost of ownership of the Bryston can be lower. A 20 year warranty is fantastic when the unthinkable happens, as it often does (and Krell service is NOT cheap). I like the extra power of the 7B (500w) but appreciate the 250a's sound, design philosophy and ability to double down into 4Ω more.
LOL!, All of you have to move up the amp food chain to realize Krell is far superior than all mentioned here!, I have a brand new revised krell 700cx, the only one in the country!, If all of you could listen to this, your opinions may change?, I have installed modern day caps that were not available in 2005!, To my ears, one of the most realistic reproduction of sound available at any cost!
