FWIW Jmcgrogan2 is absolutely on point. Most sources that you will attach to your pre-amp won't have "inverted phase". Probably the description arrises out of the fact that tube phono preamps often do invert phase, especially the little one tube cheapies. I have noticed that the inverted phase issue arrises most often in tube equipment with a single tube per side. Perhaps those that use a second tube as a cathode follower correct for the initial inversion. Just a thought.......
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,
