This CD player is well-built, with glitch-free dual D/A converters and dual-mono construction - each channel is fed an independent signal, as opposed to a shared signal, so the sound it reproduces is more accurate and 3-dimensional (sounds like you're running dual mono amps). You insert a CD upside down, because Nak locates their laser on the top, shooting down on the CD, instead of up. This way, dust can't collect on the lens over time. (ingenious!). The player is heavy, not like the cheaper units. No remote. Tested & working.
