Vertically and passively bi-amp the Pulsars with a pair of AHB2 amps, rather than bridging. Plus, what George said.
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?

@georgehifi - Well, George, your post on the other thread was what made me start to question whether I should go the bridged mono route! I've seen posts by others that stated that going bridged mono was awesome, or words to that effect. (Now, I read these discussions regularly and mostly lurk, lacking anything worthwhile to add - and I avoid the flame wars about cables and such, but... ) I know there's a significant amount of experience represented by quite a few of the people who post here. So I started the thread hoping for some good advice, and really appreciate yours. No point in spending money (or spending it wrongly) on improvements that really aren't. |
Actually you might perceive an increase in dynamics with 2 amps bridged, not due to more power but due to the decreased damping factor of the amp. A lower damping factor will make the amp sound less tight and it may give you a slight bass bump at the speaker resonance frequency. Since the Pulsars are an easy load there's no harm in trying. |

mrdecibel seigen What I will also add, if one amp has enough power to easily drive said speaker, you can gain extra dynamics and more bass grunt without losing quality by what I said before. To vertically passive bi-amp two stereo amps (linked). What happens then is all the bass power from the power supply from one amp, has it available to just that one bass driver, of the channel it's hooked up to. The other has the same. So you can get better sound with two amps, (just not in bridged mode.) http://www.av2day.com/wp-content/uploads/2014/05/biamp2.jpg Cheers George |
