I have tried to solder 680 ohm resistor and 470 ohm resistor in parallel to the 90 ohm cathode resistor. 680 showed improvement while 470 gave me best sonic results.
Typo. I actually mean input grid resistor not cathode resistor.
So that is about 75 Ohms. Have you tried any lower values? How is the gain with 75 Ohms?
I haven't tried any lower value yet. At 75 ohm, my volume control is at 8:30 to my DIY Goldmund 27 preamp. This preamp is about 12X gain. I plan to connect the streamer to my 6SN7+ 300B tube amp and hear how it sounds first before making any more changes to the resistor.
