Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker

@onhwy61 I only have experience in running it in stereo mode. I am looking and specs and reviews from others to consider the pros and cons.

@d2girls from what I heard the feed forward error correction is THX. I am not sure if they designed the amplification and power stage.

Are you speculating, or do you have actual experience with the amp in different configurations?

If you have a technical background and understand what happens when you bridge an amp, you wouldn’t be asking this question.

And of course all topologies of amps behave identically when bridged, and no amps are ever specifically designed to be bridged.

BTW geek101 OP your Legacy Aeris I just noticed are 94db!! why do you need more than one AHB2, one is plenty and will do the 4ohm load on it’s ear, and not have any disadvantages of it bridged.

A bridged one beside all the cons I mentioned, will be looking at a 2ohm load and if that speaker has high -phase angles at 2ohm impedance dips, it could be even lower as seen by the amp.

@georgehifi Legacy Aeris is spec'd for 500w. I am just considering starting with a setup that does it all when dealer comes to calibrate. If I consider the cost of extra Benchmark it is 10% of my system and I can always sell it or re-purpose it.

The challenge is find 500w of cleanest power that does well in rest of the parameters (current, voltage and damping etc) and optimized for price. 

To my limited knowledge even after bridging Benchmark seems to out perform its peers. Correct me if I am wrong. I am happy to learn more.
