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 in order to make that work right you need a rather expensive digtal crossover to do it right. Then you bypass the in speaker analog network.
ssnk you really should look into Channel D's Pure Music. You do have to buy it but you get a free trial period. It will use your iTunes as a library and does neat things like network stream and up sample. It was designed to work specifically with Apple computers.

No sorry your wrong, forget digital xovers your still using the speakers internal xovers.
Just vertical bi-amp as per the link, if you have 4 speaker terminals on each speaker (remove the links between them).
The sound will be far better than bridging the amps into mono.

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.
