Is it possible to replace the potentiometer in the Adcom GFP-750 with a high quality attenuator from DACT or goldpoint? Are there folks who have done this and seen an improvement?
Probably easier to sell the 750 and get the "real" version of the circuit as made by Nelson himself: AlephP, which uses an optical switching of a relay-driven silver resistor ladder for gain and attenuation.
Yes, the Aleph P has "true" balanced inputs and outputs, and nifty separate gain and "volume" controls for max S/N within your system's sensitivity (gain) level.
