Time domain display of signal

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 out-

put- 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 well-

known Crystal Clear was integrated. For the transport

mechanism, Lua selected a Philips- version, which deli-

vers 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 allo-

wing their sound quality to easily be compared using a

single CD player as source. Also sonic comparisons bet-

ween 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.
