Puccini+Uclock vs APL NWO 4.0 SE vs PD MPS-5

Surely some of you have compared these 3 CD-SACD players, the Puccini with the U-clock vs the others two, my questions is how they compares between them, mostly when are used to play CD.

SECOND:if you think that the PD or the APL are a better option-sound than the Puccini+Uclock , the second question can be: As I own the Puccini with the U-clock, and here Europe, is practically imposible to hear the PD and very difficult the APL, do you think that the option of to buy one Scarlatti DAC, and use the Puccini as transport, can be better than the APL or the PD. Thanks.

APL Production, today, is in Europe not USA and chief designer Alex Pechyev spent time in-bettween USA and Europe - so it should be easy for you to contact Alex.
PD is very, very good but APL has tube output and I always been a sucker for (GOOD!!!)tube stage.

Good Luck in your search,
Rafael

Questions to Jonathan Tinn:

Great front end. My most sincere congratulations. Let me exploit your presense in this forum.

Dud you ever considered (GOOD) tube output stage?
Will you consider it?

When your USB input will start to accept 176/24 and 192/24 data streaming from musical server?

Can you share with us what are you "cooking" now in your magic kitchen?

Many thanks

Hi Rafael,

Thanks for the kind words. While I have always been a lover of tubes, I would say that one of the worst places to have them is in a DAC. A properly done solid state analog output stage can sound much better than a tube DAC. There is too much distortion and noise produced by tubes. Really I would not even focus on tubes versus solid state here. There are much more critical things going on like the conversion itself.

Currently USB is not ideal nor is it that important for use with a music server. Our unit accepts anything up to 24/192 through either AES or SPDIF. We have many customers that are very satisfied using USB to SPDIF converters in order to achieve 192kHz if they cannot use AES or SPDIF sound cards.

Right now we are extremely back ordered and focusing on filling orders. When there is something to announce, I will let you know.

Best Regards,

Jonathan Tinn

Jonathan,
This is a very interesting comment: "There is too much distortion and noise produced by tubes." considering that the second and third order harmonic distortion that John Atkinson measured during his measurements for the Stereophile review of the Playback Design unit appears to be a deliberate attempt to add and emulate an exciter/enhancement tube-like distortion, in firmware. Would you please comment on this observation?

"There is too much distortion and noise produced by tubes."

Thank you Carlos for your astute observation. Let me also to add something.

Noise: I have new Joule-Electra preamp which got Harry Pearson's 2010 HP Editor Choice Award. OK, when I place my ear next to my speakers I hear...nothing, nada, ziltch. Total silence as in SILENCE. (The measured noise was of about 50 uV).

Distortions: The best BAT, CAT, Joule-Electra preamps have measured distortions (THD) less of 0.01%. Not much!!!!!!

All The Best
