perfect for a tube stage.
The XLR- version of Appassionato is the first one in
the world market of recommended CD-players with its
new designed 8- tubes single ended Class A triode output-
stage. One of its specialities is, that there are not
used any semiconductors. Directly from D/A- converter
output, the output amplifier, as same as the analogue
part of the sampling filter, is designed completely in
tube technology. True to its tradition of outstanding
quality, Lua creates different remarkable CD players as
for example the Cantilena SEL. This well noticed
model enjoyed the best test results in the market with
many hundreds being sold. But Lua wanted more. The
experience with the first CD-player gave our engineers
the chance to create a much better version named
Appassionato. This Appassionato XLR was to embody
the best possible sound reproduction and so a wellknown
Crystal Clear was integrated. For the transport

mechanism, Lua selected a Philips- version, which delivers
the best technical results at a modest price. A big
break-through was the newly designed 8-tube single
ended triode Class A output section with an output
impedance of only 180 Ohms. And speaking of outputs,
a speciality of all LUA CD- players is the provision of
two outputs instead of one. The second output can
drive a separate headphone- amplifier without use of
the main amplifier. This is also interesting for dealers,
enabling connection to two different amplifiers allowing
their sound quality to easily be compared using a
single CD player as source. Also sonic comparisons between
two different brands of RCA interlinks (Cinch
cables) or XLR, can in the same way be easily made by
connecting them to two different high level inputs of
your amplifier, especially if it is equipped with a remote
controlled channel switching facility.
