I have a potentiometer conundrum and need some advice. Background: I'm burning in a new headphone amp, the Kinki Studio Vision THR-1 (mfr's URL below). I plan to use this in my main system as preamp & No. 1 headphone amp. https://www.kinki-studio.com/thr-1 But this well reviewed amp has 2 outstanding issues: No remote; and it's insanely powerful--with any headphone other than a high impedance dynamic or power-hog planar, I'd never be able to get the volume pot (which zeroes at approx. 7:30 on the dial) beyond ~8:00 on the dial, if that I can resolve the gain issue by placing my sonically transparent, transformer-based passive volume controller in line between the DAC and this amp; or between after the amp. I did the former setup already in my burn-in station and it works well: the PVC lets me knock down the gain of the THR-1 to any degree I like, with no apparent sonic degradation...so far, so good So here is my question: which of the following component wiring scenarios makes the most sense electronically: Option-1: Wire in the PVC after the THR-1; set the volume pot of the THR-1 to 10:00 or 11:00 on the dial; then control the actual system volume via the PVC's volume pot (or) Option-2: Wire in the PVC between the DAC and the THR-1; set the PVC to a known workable gain setting (currently ~12 noon on its dial); then control the actual system volume via the THR's volume pot Option-1 would be far more convenient than option-2. But what I can't wrap my head around is whether there is some advantage of one method vs the other?
