Thanks for the heads up, already bidding on that one but after a few of these so was wondering if there were any more available. 

I was planning on using these amps in either 8 or 4 ohm bridged mode. Just to check, does the gain of the amplifier increase by 6 dB when operating in bridge mode?

Okay great thanks for that info. 

Do you know the input sensitivity as well?

I think you can calculate it as follows if not:

Normal gain = 32dB
Bridge mode gain = 38dB
Power output at 4 ohm bridge = 2400 w
Voltage at 4 ohm bridge = sqrt(2400 * 4) = 97.98
Voltage gain in bridge mode = 79.43
Input sensitivity = 97.98/79.43 = 1.23 v

Very nice rack, they do look like they're in great condition. Are you interested in selling them or not sure?
