Jfrech: I hope you post your abservations here on the IO Sig vs the P10SE. The strengths of the BAT that you described are exactly those that I seek more than anything else, i.e, the harmonic richness, decay, 3D. Lower noise and thus resolution are also important to me, but secondary to these other issues. Also, did you compare the P10 vs the P10SE? and if so, what were the SE's strengths? I understand there is another tweak to the SE for its power supply. If it is anything like the power supply change from the 30SE to the 31SE, this could be one incredible phono stage.
