I'm not sure if this is an issue or not, but as I turn my amp up from zero volume, there's a right bias where the gain is noticeably higher in the lower volume region. Thought it was a mechanical problem with the diaphragm at first but I checked this on three different sources, and three different pairs of earbuds, concluding a slight gain on the right side. At higher volumes, the gain isn't so noticeable, but I feel like one of the channels is just a touch off. It's so minuscule that I can't figure out exactly what's wrong, but I notice every time I use the source without the amp, everything is proportionate, and I hate being picky, but I can't stop playing with it instead of just enjoying my music. The product is great, sound stage and depth even for a non-audiophile like myself is definitely improved. Should I return the product and hope for a more solid device or try to get over it?
