TVC Promethius versus Bent

Any impressions on differences from this that have tried TVCs from both these companies? Also, I'm not sure why a transformer would help over of a passive resistor based attenuator (assuming a very high quality pot)assuming drive, low output impedance source, low capacitance cables, high sensitivity amp with high input impedance (100kohm). If more is less, why isn't adding a transformer just more, though minimal, distortion? Sort of two questions, but I have a high quality passive volume control, but have an interest in the TVC idea, especially these two brands or something made by Kevin Carter.

i own a bent tvc-based preamp. it is my reference. i have also heard the promitheus with the silver wire and silver rcas..

i prefer the bent wired with continuous cast copper and vampire wire copper female rcas over the prometheus with silver wire.

hi bob:

i can't comment on that , but i did audition one, during 2008. i think one of the considerations for me is internal wiring. i generally don't like silver. also, i prefer copper rcas, especially vampire wire.

i would conjecture that my bent would be softer sounding than any promitheus preamp, and therefore, more forgiving of questionable discs.
