The lower the output voltage the higher you will have to turn up the preamp to achieve the same volume as one with more voltage. And you will probably hear more noise from the amp and or preamp when the volume is turned way up.
Preamp output voltage?
Could someone please explain preamp output voltage? What effect (if any) does it have on amplifier performance, S/N ratio, dynamic range, and most importantly, subjective listening? I have an old Adcom GTP-500II tuner-preamp with a rated output of 2.0V RMS and a peak output of 10.0V RMS. I am considering replacing the Adcom with a new AV surround receiver, and I would use the pre-outs to power my front KEF 104.2's with an Adcom GFA-555II amp. I am looking at the Outlaw 1070 receiver, but it only has a pre-out voltage of 0.76V. The Yamaha RX-V657 receiver claims a pre-out voltage of 2V. Will either of these receivers (or any other receiver) be likely to sound as good, driving the Adcom amp, as the Adcom tuner-preamp for 2 channel music?
