Greetings head-fiers!
I've recently assembled a Mini3 amp (gain 2) to use with the LOD of my 6G ipod. I've built one canare interconnect so far and will probably make a silver one this weekend. The issue I'm running into is that at low listening volumes the right channel is slightly louder than the left. I've got a pair of Nuforce NE-7Ms that have 13.6 & 13.7 ohm impedance (right & left). I'm certain its not the LOD that's causing the imbalance as I've checked with other mini-to-mini cords from the ipod's headphone jack with the same result. The headphones and my car's stereo work fine as well. And yes, I know the Mini3 shouldn't be expected to run well at low levels.
My question is where to start replacing resistors (or capacitors??) on the board to balance out the sound. I'm not suggesting other rated values, just using others I didn't use after the matching process. I matched all resistors leaving at least 4 extras and usually to within about 0.2% of eachother.
When I slowly turn up the volume from nothing, the right channel becomes about as loud as a conversation in another room while the left is nearly silent. At normal levels, the focal point of the soundstage seems to be about 25-30 degrees to the right of the direction I'm facing (making up my own terminology here
). I hope this is an easy fix, but I will understand if using these iems is unreasonable...
Thanks for any help you can give!
Eric
PS: Thank you Ti for such a wonderful DIY project. Expect more business from me soon
