Can AVR DC Output at Preamp Outs be Increased?

Can the DC voltage output at a typical AVR be increased from a specified 1.0V output to 10V or more output Volts?

If so, would this be done by upgrading the DC voltage opamps in the preamp out section of opamps in the DC voltage section of the receiver. Or is there another way this could be accomplished?

And has anyone ever done this?

Let me simplify.

For example, the Audio Research SP3 preamp is rated for 25V RMS @ 1 kHz at all outputs (https://www.arcdb.ws/model/SP3).

My AVR is rated for 1.0V RMS @ 1kHz at all PREAMP outputs.

I wish to increase the PREAMP output of my AVR from 1.0V RMS to at least 10V RMS at all PREAMP outputs.

In theory I would think I could accomplish by changing out a couple of op amps. 
How easy and/or complicated would it be to accomplish this?

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!
