Luxman DA-07

A landmark a Luxman's only separate d/a converter (of the pre/post-Alpine and Azden periods).

At the center of this massive block of forward engineering was the FLUENCY d/a section which was to "recreate" the upper harmonics lost with digital formats and their necessary low-pass filter.
The DA-07 has no low-pass filter and no digital filter either and is based on interpolation theories to achieve its extended goal.

Of course, at 27 kilos and 400,000¥, there was more to the DA-07 :
OFC epoxy boards, 70µ OFC tracks, 11 separate regulations, two big toroidal transformers, two-chassis-rolled-into-one holding a 10-compartment structure for absolute isolation, 18mm front plate, six digital inputs, two digital outputs, three analog outputs, highly rigid composite chassis base, copper-plating and ultra componentry allover, pure Class A throughout and more.

No one would expect less from Luxman, but what remains rather strange is that -albeit praised everywhere then- the DA-07 is... very very rare, just like its DP-07 companion.


More about those who developed the Fluency DAC at the Tsukuba University, the white paper of which was published august 1988 here and here and Junji Kimura who uses an extension of the Fluency (NOS) today at 47Laboratory, plus a thread on diyhifi.org.
A real DA-07 here.
