The way it was explained to me is if the preamp is inverted one must switch speaker leads + - at either amp end or speaker end. But because of the possiblity of the amp being inverted one must try both ways. Taking some tracks with good vocals, the proper way will show more Depth on the vocals. I was able to notice this but it wasn't a big difference but it was there. In this hobby it is about getting the small gains and not costing anything is a Bonus.
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
