Faux reverse RIAA? Was Source for Turtable Cartridge?
"Trevor" wrote in message ... "Frank Stearns" wrote in message news:kJ- - I'd really like to try the Grace 802. Besides the great pres, it has superb on-board A-D. Inputs are nominally 5K; was thinking perhaps I could get away with series 39K (or 44K if I can find a precision value in that range) to make the cartridge happy. You should probably rethink that. Given a nominal cartridge output of around 5mV, you will get around 0.5mV into the Grace after the 44k+5k to 5k attenuator, then you need to boost the bass by about 20dB. Not necessarily a recipe for improving on a cheap phono pre-amp IMO. Trevor. And cutting your dynamic range, and raising the preamp noise. geoff |
