Default Faux reverse RIAA? Was Source for Turtable Cartridge?

- 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.
