Martin also has two AD-7 decoders. In
addition to Eero's comments, I would add:
o It is limited to only four speakers.
o It came in 120 and 240 Volt versions, so
you might want to ask.
o I have an early 120 V version where the
low-voltage power lead is wired-in, no plug.
o They seem to have been sold with several
different arrangements of sockets on the
back. DIN sockets seem the most popular,
but again you might want to ask.
o My last one cost me US$50, so 40 euros
seems fair to me.
If I was starting now I would go the fan-less PC
and soundcard route. However, as as been
pointed out, the only software solutions
currently available are ad-hoc and so will
involve some work.
I used an AD-7 for many years, primarily to
listen to stereo albums in Super Stereo mode.
It did the job.
Regards,
Martin
