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.

Somehow, Im not convinced that a thread drive is the best for a device that constantly changes speed, I see it as a better alternative for a turntable system that keeps speed constant?
Wow the PD is impressive it has made no noice since 04-18-10, its completely silent:-)
I have personally listened to the Burmester 069 for over 50 glorious hours. It is simply the best source I have ever heard. However, it cost the same as a BMW.
