Yeah, a lot of tube gear is phase inverting, I had to do the math when I had Conrad Johnson and then a Audio Note tube DAC. From what I've heard if both pieces the amp and preamp are both inverting then normal hook up should be fine but if an odd number of inverting,llike when I added a tube DAC then the speaker lead inverting came to play. Some debate the importance as many recordings aren't in phase but it does seem to make a difference in focus vs. more diffuse sound. Fortunately, I didn't have the same issue as you and the poster describe. However, as one poster mentioned I used a 4 ohm tap off my power amp though my Dyn's were 6 ohm, when I had the amps converted to mono I discussed this with the tech and they suggested often 4 ohm output is better though speakers may be more impedance.

The phase inversion and the 4 ohm tap change that were recommended by inmates made a substantial difference. I did find an older recording (Manhattans: Kiss and say goodbye) where bells were out of phase...strange as I was so accustomed to hearing them sound "correct" when I had the phase the incorrect way. This is the only recording so far that I have noticed something sounding wrong. Despite my poor description of what I was hearing, You all collectively were able to help me. Fantastic. Thanks.
Just switched to a tube preamp as well with 6922 circuit.
