Thanks for the great info! As to, "have you actually tried", I'm not sure what you mean. I do not have a 3080. I am in the market for a new AVR, mainly considering Denon and Yamaha.Sorry, but you did not understand that part correctly. Those Denon AVRs you are referring to can do quite well at well over 3 Volts if you disconnect the internal amps or use preamp mode. If you don't, they can still do well at over 3 V but at above 1.4 V-1.5 V, SINAD would begin to drop, to about 75 dB at 2 V and may be a little more at up to 3 to 4 V. 75 dB SINAD would be about as good as the Marantz AVR and the AV7705 just to put things in perspective.
Someone has already answered your question on the 3080Krell combo. It won't be able to drive your Krell amp to its rated output on the test bench for sure because it would likely shutdown at about 2 V. For real world use though, I bet you may be fine because:
a) You may not need 400 W into 8 ohms or 800 W into 4 ohms.
b) Even if you get close to those number it will mostly be only during the rare peaks that may not last long enough to trigger the 3080's protection system.
Have you actually tried?
With respect to the new Denons, can you disconnect just the front L/R internal amps? And would that do me any good, with respect to rising distortion above 1.4 to 1.5 V, if I'm still going to be using the Denon to power the center and L/R surround channels? The AVR would then be powering 3 channels.
With respect to the 3080(or the A6A), I will be using the XLR pre-outs, not the rca pre-outs. I hoped that there might be more voltage at the XLR pre-outs, such that the 3080 would be able to provide the Krell's 2.7 Vrms sensitivity level without any risk of shut down.
