I do, it retails for $3500 and has had stellar reviews.Which phono stage is this?
I agree with you on the phase issues and at some low and high frequency a transformer is going to shift phase and I think that the shift at high frequencies is much more of a concern than at low.
musical timing and natural harmonics are destroyed by phase anomalies.yes.... bell labs found a strong correlation between phase shifts and voice intelligibility. Higher order odd harmonics are dissonant to begin with, throw in some phase shift and i suspect they get downright ugly.
Look at the bottom end in your graphs - its there for all to see.
I don't follow. transformers like all systems have a finite bandwidth and with that they have finite linear phase. It is much more of a struggle to get a full 10 octaves of flat phase response out of a transformer than an active circuit so it becomes increasingly important to place the plateau of linear phase in the proper spot.
