Summary: I bought it for the hi-end playback of CD's. It is excellent compared to my former Sony player. The bad news is it has been in the shop twice and still sticks on even brand new CD's. I has gotten better on DVD's. I've complained to Denon and get nothing but BS. I'll never buy another Denon product as long as I live. Avoid.
Summary: Didn't know how much difference a good player makes with my DVD's. This one showed me the light. It's big, it's bulky, but boy what a blast to use. Hooked up with HDMI, Logistic universal remote controls it, and I just sit back and watch movies with out the hassle and edgy video like before. Well worth the investment.
Summary: When I was on a market for the good DVD player the Denon 3930CI was a clear choice. It was consistently rated as the best DVD player one could get. After using the player with DVDs of various picture quality I can only confirm it. I tested it against Sony PS3 and Oppo 980 and Denon would always give me the best picture quality.
Summary: I had high-end 60lb $2500 Sony SCD-777ES SACD player and Oppo 971 DVD player. Due to upgrade to a new Blu-ray player, I need an extra space so decision is to consolidate the SCD-777ES SACD and Oppo 971 DVD into one high-end SACD/DVD player. I tried out the value Oppo 980 & 981, but its SACD performance is not the same level as Sony SCD-777ES. I tried $1200 Sony DVP-NS9100ES; good DVD but the SACD sound quality is not Audiophile grade yet.
Summary: I purchased this unit to replace my previous 3930 which began acting up; HDMI output began functioning sporadically, then CD functions began failing, tracking and other audio noises. I had replaced it with an Oppo 95 which I found to be bass shy. I want all my low frequencies, so I found a brand new unit on Ebay for $400 +15 ship. My previous unit was a refurb which lasted almost 2 years before trouble set in.
Pros: EXCELLENT SOUND
Cons: NONE THAT I CAN THINK OF BUT SOME UNITS FAIL
