A landmark unit weighing... 27kg.

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 had no low-pass filter and no digital filter either and was 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-chassis-rolled-into-one holding a 10-compartment structure for absolute isolation, 18mm front plate, six digital inputs (3x coaxial, 2xTOS and 1x ST), two digital outputs (1x coaxial, 1x TOS) three analog outputs (variable RCA, fixed RCA, fixed XLR), highly rigid composite chassis, 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.
