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?

George,

How do I split the output from the pre-amp/DAC? Does someone make a decent splitter cable with XLR terminations? Or am I missing something?

For a long time now, on more than one thread, my opinion is that George continues to be wrong. The amps are better in Mono. I reviewed them for Dagogo.com, and I believe I am correct that George has never used them.

I might consider an Audioquest product, but since the AHB2 only accepts XLR, those would be an issue. Call me crazy, but a guy who invests in Nordost cables has no business buying a Chinese splitter for $10.99 on eBay without some nice references from others. I suspect the improvement from vertical bi-amping might be obscured by the crappy cable in the middle.

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