Benchmark AHB2 - To 'mono' or not to 'mono'


I own a single Benchmark AHB2 amp and have been considering another in order to run both in bridged mono mode, which will provide significantly more power to my speakers and presumably, greater dynamics. I've read in other threads where other owners (and perhaps others with opinions) had implied both positive and negative impressions concerning this approach. Assuming I'm not considering purchasing other amps at this time, does anyone have experience with both approaches and will you please share your impressions?

@wwoodrum, 
I do not have this amp, but I am looking to upgrade and have looked into benchmark.  What speakers do you have and what other amps have you compared it with. Thanks.

Benchmark AHB2 - To ’mono’ or not to ’mono’

I’ve said it before in other threads here it is again

"Nice amp, if you want to hear them at their best, don’t bridge "if there’s no need to", as all you’ll gain is watts, everything else takes a hit when you bridge amps.

Pro’s=
More watts.

Con’s=
Worse damping factor
Higher output impedance (has relevance to damping factor)
Lower stability (especially into low impedance’s)
Current ability is reduced (especially into low impedance’s)
Higher distortion.

And if you have two of them better to run them in stereo mode and vertically bi-amped, instead of bridging (mono’ing).

@pcc67 - The only objective comparisons (head to head) have been with a Bryston 60W integrated amp and with a Rega Osiris. The comparison with the Bryston and the superior mid-bass resolution of the AHB2 during my in-home trial of the latter was the basis for my decision to hold on to the AHB2.

The comparison with the Osiris came later. The owner of the Osiris (my brother) left the duel with the feeling that he preferred his amp hands down. He's all about the dynamics. I thought the AHB2 portrayed everything more cleanly; more definition and air between the individual voices. The AHB2 was slightly less dynamic, which I attributed to its lower wattage delivered to the speakers. (Hence my curiosity about bridging, because I did appreciate the dynamics; it just isn't a deal-killer for me like image is.) 

Speakers used for these comparisons were Joseph Audio Pulsars.
Vertically and passively bi-amp the Pulsars with a pair of AHB2 amps, rather than bridging. Plus, what George said.
