Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker

Simple answer is to buy one and see what you think. A second is just a click away at the same price. The top half of the Aries is not that hard to drive just like the top half of the Vandersteen powered models. My choice would be the BHK 250 which you can get for way under the retail price from selected on-line dealers.

Your prepared to spend $6k for 2 x benchmark's that in my opinion will degrade substantially once bridged.

Or get the right amp designed by John Curl, only equaled by Nelson Pass in my books, and get his
for $6k

 I have AHB2, few month old.  In instruction manual rev G  p.22 it states:  

Output Current: 29 A peak into 1 Ohm, both channels driven 

The same is on their website (it used to be 18A).  Perhaps they improved power supply (higher limit).

@georgehifi Benchmark has no peer in controlling distortion , zero cross over distortion but without class A hassle. I will get answers regarding damping factor and total current. I am buying them used btw.

@kijanki thank you so much pointing fhat out. Will make sure to newer revisions. 

From the review: 

"So, what about that comparison of cables between the Benchmark and Clarity sets? I set up the following components and rotated sets of cables between them: Salk Audio StreamPlayer III, DAC3 DX, AHB2 Amp (two in Mono mode), and PureAudioProject Trio15 PAP Horn 1 Speaker. "

and 

"Again, the four components in question were the DAC3 DX, AHB2 Amplifier (2)"  

I think the typical reader would understand that "(2)" meant used in Mono mode, as I had been doing earlier.
