Summary: I have sold these units side by side with MANY other cd players, from entry level to high cost audiophile. The Denon dcd 1650 offer the best frame and build quality I have seen. it does weigh in at over 20lb. the reliability of these has been good, and the sound quailty is VERY GOOD. It is as close to high end audiophile sound as I have seen without the $2,000+ price tag.
