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, do not chintz out and get the AQ splitters. If you have considerable funds in your system, get a superior product. Having compared directly several times in several systems the AQ splitters (RCA) to various Y cables (I have also compared the AQ RCA Y cables, and they are average), I suggest you get a superior product, namely the Audio Sensibility Y Cables. 

I reviewed the Audio Sensibility Y cables, both XLR and RCA for Dagogo.com in connection with my Schroeder Method of Interconnect Placement (which I have done with the Mono Benchmark amps- revolutionizes their performance), and continue to use them. They are superb and worth the money. You will have superior sound quality using the Audio Sensibility Y cables. Yes, they are much more expensive, but are much better. I would not skimp on that.

I am not attempting to make this a bash George thread, as I have seen him give good advice. But in this particular detail I believe my advice is better, obviously because I have extensive experience.

You can elect to have AQ manufacture some custom XLR Y cables for you from the cable of your choice. That is not cheap at all, possibly far more expensive than the Audio Sensibility Y cables. They might outperform, but that is not a given. The AQ Y cables I had made are far more stiff and that creates issues in some setups where you have to bend the Y cable. Given these options you would be wise to avoid the hard splitters. I have used other splitters as well, and prefer Y cables holistically.  

In conclusion, you have several more significant steps to yield higher performance. You have not yet come close to maximizing the potential of the AHB2. You will also want to pay attention to power cords on the amps, even though -as you might suspect - some declare that it makes no difference. It does.

Anyway, it's on now to the all important listening session!   :) 
but since the AHB2 only accepts XLR


Plenty like these around, if you look at all differing prices.

I am going with the opinions of those who say they’ve done it.

Pitty, no I’ll rephrase that, sad, you’ll never know then, just how much better your system can get, by vertical bi-amping, instead of bridging (mono’ing) your amps.

Cheers George
@George - I’m not questioning the theory behind what you say. But I believe in empirical observation. Tell me you’ve done it  both ways with this amp and your way is better; I will gladly spend what I have to in order to try it. (That said, TWO pairs of Nordost cables is an investment not for the faint of heart, regardless of length!)
@douglas_schroeder -I have the Frey 2 on the power side from a Qb8 that is fed by a Valhalla2 20-amp cable. The results are sublime.
