Autio, re-reading my post I did not make myslef clear. Swapping the speaker leads at the amp binding posts (+ to - on each channel) I could hear no difference, meaning the voice on the test CD stayed centered and was well imaged. However, with the speaker leads wired correctly, swapping the RCA leads at the amp inputs so that L from preamp output goes to R amp input and R preamp output goes to L amp input, I could hear a difference. The voice on the test CD was not centered, instead appearing as if it were coming from different areas.
Phase Inversion in Preamplifer?
I just bought a used Audible Illusions 2D here on a'gon. This will be my first venture into separates. I've learned that AI preamps have inverted phase, so it's recommended that I switch +/- polarities at the speaker-amp hook-up. OK. But according to AI literature the phono stage of the preamp is NOT inverted, only the output stage is. So, since I listen to both vinyl and CDs, what do I do? Should I reverse speaker wire polarity or not?
Incidentally, the amp I'll be using is an ATI 1502 -- still haven't been able to find out if it inverts polarity or not. But based on my (limited) research thus far it appears that phase inversion is a design of preamplifiers more than power amplifiers. Is that right?
Thanks,
Rich
