I owned a 1650AR for a few years, and I agree, it has excellent build quality for the money. After using it for a while, I bought a Dodson DA217MkII-D DAC at a good price on AudiogoN to go with it, which made a noticeable difference in the sound -- better resolution, greater purity, and more precise imaging.
You may want to investigate the pros and cons of investing in an external DAC and digital cable, at various price levels, versus a mod to the player.
Good luck!
