I am considering a purchase of either the new Integra DRX 3.4 or Denon avr 3700H but I plan to use the preamp output to connect to a 3 channel amp that requires 2V to reach full rated power. I am leaning toward the Integra as I like Dirac room correction but what concerns me is the pre amp output voltage of 1V versus the Denon that has amplifier disconnect and can run maximum 4V unclipped from the preamp. Attached is what I see as specs for the Integra DRX 3.4. Any thoughts? I called Integra support and the representative said he spoke to his engineer and 1V is max for their pre-out but that does not sound correct to me.
