Re: [ARSCLIST] Non-RIAA preamp

[Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>]

I can't imagine there's all this phase shifting going on in an analog amp, unless it's a reshift 
from shifting done in the cutting EQ. Otherwise, well cut LPs wouldn't sound good, and they clearly 
do. Now, how closely many analog preamps follow the RIAA curve, or if they're designed with proper 
gain staging, that's a whole other, amp-specific question.
