Any Bryston 4B3 amp owners out there?


I'm strongly considering a 4B3 amp purchase. Bryston's warranty and build quality are as good as it gets and the price is in my budget. Pro reviews are good, I'm just wondering what owners may think. Are you pleased with the performance, what it's matched with, etc. I'm already aware of the specs, the story behind the design, and all the press release stuff. Plain talk would be appreciated.

Thanks

I bought the 4B3 amp and sold it fairly quick.  I lost a considerable amount of soundstage on the top end compared with my older CJ solid state amp.  It had very nice attack on drums and bass, just didn't fit my system otherwise.  I'd audition if possible, yes I agree that warranty is hard to beat.  Also make sure to verify that the reseller of person selling bought form a reseller, they changed their terms on the ability to transfer the warranty a few years back.  
Thanks hikmer, honest appraisal is what I want to hear. I'm using a Parasound A21 right now, and I'm trying to figure out if making a change would be worth the money (different thread). I look hard at Bryston because their warranty is so darn good. Simaudio also offers a good warranty, but their equipment is harder to get my hands on.
I'll be honest, any reputable company making gear these days should last a very long time warranty or not.  An amp doesn't have a lot of moving parts so you really shouldn't have to worry about things breaking....I know a long warranty is a nice thing to have but will you still own this gear in twenty years?   Yes nice to have if you resell but I'd consider other brands at the $4K price point....there is a lot out there.
I own a Simaudio 870a and really love it but it is 4x the cost of the 4B3....Check out this thread on Agon. ’My Long List of Amplifiers and My Personal Review of Each!' The OP gives his review of dozens of amps and what he thinks of them including the new cubed series from Bryston...very informative.
Good luck!
I've recently acquired a completely rebuilt McCormack DNA-1 gold (with extras) which is really musical and for under $3K quite a bargain.  While I did not compare against the Bryston 4B3 directly, I can say I am much happier with this amplifier than when I owned the 4B3.
