Luxman D-700s

Part of the re-launch of Luxman : post-Alpine, or the last period of actual worldwide visibility and proper sales - even if with much smaller lineups and shrinking distribution.

The D-700s is beautiful, very beautiful... on the outside.
Like the D-105 or D-107u, inside is less impressive : the D-700s is a big but empty box with the servo & audio stages taking the right third, the Sony KSS drive & transformer center third and... nothing in the left third !

The servo and audio stages are laid out on one single PCB with proper heatsinking and sizeable caps scattered throughout.
The center is made of two non-descript "Sine-Magnitude" 20bit BurrBrown, 8fs digital filter and the then-ubiquitous Pacific Microsonics PMD100 HDCD decoder.
A small supplementary PCB holds the XLR outputs.

The transformer has four secondaries (FL display, FL filament, DA & HDCD, transport & drive) within which are five separate regulations for all of these sections but the FL filament.
I don't know which Sony KSS is inside : KSS-151 or KSS-240 perhaps ?

That's it - far far far from a D-500X's or DP-07 !
Like the D-105 or D-107u, Luxman never showed an entire nudie in its catalogs. 180,000¥ was blatantly overpriced for such little and undistinguished hardware.
To name but one, the CDP-XA7ES cost no more than that and was exemplary regarding hardware, layout, parts and mechanics !

The D-700s was not made by AZDEN, nor by Goto D.S. or by Aimor (the latter two came only later in the Lux galaxy of build-shops) but by a certain T. Sound (mainly) and Hashimoto (on the side) - whoever these two may be.

A real D-700s here.
