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?
Trolls as in the mythical beings that live in caves and assail unwary travelers; the modern context is here:

[off topic] Not that I’ve never appreciated really nice work by the very best, but most of them aren’t even close. To wit: this review of Audioquest K2 speaker cables...

tobes, at my age you have to piss all the time. woodrum, that definition of troll adequately fits audiophiles in general as it seems there is as much mythology as there is reality in the practice. Trolls are most dangerous when they are trying to sell you stuff.
Recently I added a second AHB2 to my system to run it in mono.

I was running MacBook Pro (JRIVER) > Benchmark DAC3 > AHB2 > ATC SCM19v2 (as of yesterday – there are two ahb2, running in mono and providing 380watts into 8ohms). My speakers are ATC SCM19v2 (85db / suggested power from manufacturer is 75-300 watts), so I was hoping to get better performance with more wattage.

 After reading posts from different fellow members on this site and other forums, I was not expecting any big changes in the sound quality. But boy, I was so wrong. I guess different ear hear differently.

 I was very happy with single AHB2 (100watts) pumping music into my speakers, with great sound-staging, tonal balance, accuracy, clarity, bass punch, excellent mid-range etc etc. But sometimes, with some tracks, I did wish for fuller/warmer sound, and was doing google research into some tube preamps to use with my setup for the occasions when I really wanted that extra warmth. That problem is now solved with two units.

With two AHB2 (in mono configuration), the sound quality has changed considerably. Tracks which sounded thin earlier, were fuller with more ‘body’ and warmth. The sound staging is definitely much better now. It has completely changed my listening experience to say the least.

 I am expecting to spend more time with my system over the coming weekend, and will share more soon.

Hopefully, I will like this change.

That to be expected with half the damping factor and double the output impedance, that will always make the bass and lower mids sound richer.

Now try vertical passive Bi-Amping with the both amps back in stereo mode, and prepare to be amazed!!!

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.
