For what it's worth: I have the same setup, except for a higher output MM cartridge. I have the soft-start board, which reduces the Paramount gain about 5dB, but I still also have 12dB inline attenuators (Harrison Labs) at the Paramount inputs. You can add a voltage divider with one extra resistor per Paramount, which is probably the best idea - see my notes on signals and noise, on the Community page. I have not done this because I have two more experiments planned - a 6SN7 driver conversion (takes another 4dB off the gain), and an internal gain trim. My plan is to silicone a screwdriver-adjust PEC pot next to the driver. If I ever get around to these projects, I'll take pictures and post them!
