This was posted on the chip amps forum, however it was suggested I post here also.
Hi all,
I have built the LM3875 Dual Mono Premium Kit successfully and have used an ALPS 50k log pot on the input side, however the music sounds "restrained" on playback.
But, if I use the preamp section of my receiver (Yamaha RXV1900) and turn the pot all the way up on my LM3875's I get the sound I am wanting. My source is a Gigawork DAC.
So, what is the best way to move forward? Will changing the ALPS out for something else be OK, or do I need a preamp? Is my ALPS at 50K to high? How do I calculate the correct value? If the preamp route is the way to go, can anyone point me in the direction of a suitable kit?
Thanks,
Dan
