Bryston vs MBL


Im ready to buy my first set of monoblocks to use with my AR 5SE and Dynaudio Confidence C4.  Ive been waiting for a pair of MBL Reference 9007 to show up on here but none yet.  While waiting, ive been reading up on Bryston monos.  I think a used pair of 7B3 might hold me over for a few years to come if fthe MBLs dont show up second hand.  The 7B3 have plenty power and is predecessors have great reviews.  Any thougts would be greatly appreciated.  If i get Bryston, im sure ill upgrade in next 3 yrs.. If MBL might upgrade in 5 or 10 yrs.

" Another high power consideration for you is the Aesthetix Atlas. Underappreciated in my opinion, and resale units seem like a bargain. I own a stereo Atlas amp."

Its funny you bring the Atlis up. I know its a good amp but I won't recommend anything I haven't heard myself. But it is tempting, especially since I have a Calypso. Have you compared the Atlas to Ayre? I have 2 V-5's in my system now and I haven't heard anything that makes me want to upgrage. Just curiouis. 
MB1, Your point about the Pass 40 vs Krell is well taken! I plugged in my Krell 250 in place of the Levinson and the extra 300 watts at 4ohms was negligent.  Sound was tinny and lifeless with the Krell with the additional wattage that it supposedly delivered.  Im sure Krell has better amps but for now, steering clear of them.  My old Sunfire Cinema Grand sounded better.  So yes, your point about power is well taken. Perhaps i just proved to myself that power doesn't mean a whole lot.  I posted a new thread about Pass XA200.5 vs Pass X350.8.  IS the power difference significant?  Sound quality or characteristics?  
With reference to tubes, i decided to go with SS for now.  If i were to venture into tubes for amps, i would be looking at AR 250 monos to team up with the 5SE.

I have not compared the Atlas to any of the Ayre amplifiers. I bought it on a recommendation from Audioconnection as a match for my Calypso preamp.

My system is posted here if you want to see it.

Say no more. John R is on another plane of existence compared to other high end retailers. In my opinion, AC and The Cable Company are the 2 best audio stores in the US.
