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

The long outdated (3-4 years old) NWO-2.5 featured 20 per channel AKM DACs and differential/balanced tube output stage with 6H30 tubes and Lundahl transformers (no negative feedback). Some measurements below.

Here is a graph with 1KHz at 0dB

Second harmonic at 0.003%, third at 0.001%, noise is at below -120dB or 0.0001% above 60Hz. You can see some 60Hz interference picked-up by the output transformers, but at -100dB or 0.001% it is something you cannot hear.

Another graph with 1KHz sine this time at -90.31db showing the resolution at this extremely low level.

All of the above measurements made with CD (44.1KHz/16bit).

Hope this helps!

Best,

I suggest you also listen to the new Wadia S7i or the new Burmester 089 or even better the Burmester 069 if your budget can allow it. I personally prefer these over dCS. I have not heard PD.

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.
