Can AVR DC Output at Preamp Outs be Increased?

This is the second stupid thread I have read this morning! The first was by dbefus85!

Why do you want to do this? Only the AVR's speaker outputs need more voltage to drive the five or more speakers in your home theater setup. I assume your AVR already has at least 5 channels rated at 100 watts (28 volts AC) each! That is adequate for most speakers! 

Stop trying to second guess the engineering team that designed your AVR (Denon, Pioneer, Technics ...). Don't be an I***T!

Your power amp can handle 0.75V or 2.5V at the input.  Why would you make your preamp output >10V?  It wouldn't work with you amp.

In general, it is better to put more gain in the cleaner environment (preamp), but both pre and amp have to be designed for that (like my Benchmark DAC3 and AHB2) - otherwise it doesn't make sense.

In addition it is not an issue of different opamp - they don't set the gain, circuitry around them does and changing it would be like redesigning it.

+1 kijanki!
