I have a Sim Audio PSP phono preamp.
After opening it up, one quickly realizes they charge a boat load of money for a nice chassis and not too much else... Anyway, I was thinking of upgrading parts on it. Also, it's output is way too high for my Grado Platinum and I would like to lower the gain. Only problem is I am clueless as to what to change. Can anyone help with this? I included a top side photo. I'll include a bottom side photo in my next post. I was even thinking of tossing the bd and putting something else in it's place. But I want to try improving the present board first. Suggestions? TIA |
