Super-tweaked vesrsion of the bestselling D-105u CD player - super-tweaked version of a rather banal-player-with-a-twist.

The twist being, naturally, the two 6CG7 tubes glowing through the front. Also the generous amount of copper foils placed over the digital-to-analogue chips, ICs, caps, power transformers and output transformers. Yes : the D-107u uses output transformers instead of analogue low pass filtering ! I believe the digital-to-analogue conversion to be done done by two Burr Brown PCM series ; it is 18bit with 8fs oversampling at any rate. Besides the market-dependent presence of wooden sideburns, these are the very good points.

The bad points are... a build-quality which is obviously on the low end with dispersed cabling back and forth and back and forth and a lot of plastic, too. Worse yet, the pickup is a Sony KSS-152A - nowadays unavailable. My own D-105u has a dead KSS :( Given the effort spent on the audio part, Luxman didn't think necessary to offer a digital output either - even if the earlier D-105u did have one !
In other words, Luxman could have taken advantage of a series that sold very well to make a real topper with visible high-end build quality - but didn't. Sound-wise a fair player but no more - the build quality prevented the D-107u to play in the league it was destined to.

Design-wise, the entire series (LV-105, LV-105u, LV-107u, D-103, D-103u, DZ-03, D-105, D-105u) is somewhat directly inspired by Luxman's original prototype for its first CD player, the champagne DZ-03 being the closest version of that. Alas, this was done in a much less inspired manner. The D-107u came too late in the series and was too incoherent on its own ; unlike its earlier siblings, it is rather rare.

Detailed views of the 107u can be seen at thevintagecorner ; a service manual for it should be downloadable somewhere here.
