Time domain display of signal

Luas Appassionato Mk.III is a big step ahead in the

world market of recommanded CD-players with its

new designed 6- tubes single ended Class A output-

stage. One of its specialities is, that there are not used

any semiconductors in the signal path. Directly from

D/A- converter  output, the output amplifier, as same

as the analogue part of the sampling filter is designed

completly in S.R.P.P.- tube technology.  True to its tra-

dition of outstanding quality, Lua creats different

remarkable CD players in the past, as for example the

Cantilena Mk.II. 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 earlier CD-players gave our engineers the chance to

create a much better version named Appassionato

Mk.III. This Appassionato Mk.III was to embody the

best possible sound reproduction and so a well-known

Crystal Clear D/A converter was integrated. For the

transport mechanism, Lua selected a Philips- version ,

which delivers the best technical results at a modest

price. A big breakthrough was the newly designed 6-

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 pro-

vision of two outputs instead of one. The second out-

put 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 compari-

sons between two different brands of RCA interlinks

(Cinch cables) 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.
