The volume pot used for Chinese products is very small, about 10mm square. It is inevitable that such a small product will have large gang errors.Does anyone have a channel misbalance under 1/4 volume. It seems that right channel is very slow to come up to the match volume of the left channel.
I worked around it by lowering the volume of the DAC but i was wondering if there is a way to fix this permanently?
Another thing i noticed with this amp is even when the volume knob is set to Min I can still hear the music through my speakers albeit at a very low volume. is this normal as well?
I think the volume pot used in the PA3s is the same as the PA5 and LA90, but the size of the gang error is up to luck.
If it really bothers you, you have no choice but to lower the input signal and use it in an area where the gang error is small, or replace the volume pot yourself.
I bought PA3/PA3s/PA5 and they didn't have the big gang error like yours.
If it's been a while since you bought it and it's still possible to return it, there is also a way to return it as a defective product and then buy a new one.
