Event completed..  
 
Will be getting a loaned sample to play...  
 
Albert will try it out. (^_^)  
 
I myself did hear an AB comparison in Tokyo, using regular ndk vs duculon...and the difference was significant...  
 
So far I know two diy dacs using it that I have heard....

日本的NDK朋友恰好在黃金周假期前在香港,邀請了他分享關於低噪音NDK duculon振盪器開發及其在超hifi 解碼器上的應用。  
 
有興趣請PM我。 4月27 日(星期五)1-3pm, 旺角。

For ultra-fi DACs: NDK duculon oscillator - talk on April 27 (Friday)
A friend from NDK Japan happens to be in HK prior to the golden week holidays, and I have invited him to share his knowledge in a talk on the low noise duculon oscillator development and its applications for ultra-fi dacs on April 27 (friday).  
 
Seats very limited. Please PM me should you be interested in attending this free event. (venue in Monkok - from 1 to 3 pm)

about NDK Duculon oscillator  
(Dual Crystal Ultra Low Noise OCXO)  
 
www.ndk.com/en/ad/2013/001/index.html  
 
In digital audio devices, the phase noise of the master clock influences DAC due to jitter, thereby impeding high-fidelity audio reproduction. To enhance sound reproducibility, a crystal oscillator for a master clock with superior phase noise characteristics (i.e., low jitter) is necessary.  
 
NDK developed in 2015 the DuCULoN® (Dual Crystal Ultra Low Noise OCXO), which is a world leader(internal data, June 2015) in the market for audio-device crystal oscillators with low phase noise characteristics.
