The Denon 3910 player is an exceptional machine .Its build quality is superb and its ability to playback most formats makes it the ideal machine to upgrade .This example here had its power supply upgraded with Black Gate capacitors and Hexfred diodes.The Black Gates are about 2-3 times the size of the generic caps so a fair amount of manourveing was required.It was reclocked with a Dexa clock and its 2 ch. analog o/p stage was replaced by a LC Audio Zapfilter with had its own power supplied installed as well.The end result is an accurate, reference class player with loads of detail, depth and a lovely natural sound .
