[#21] Wyred4Sound 推出 bLINK 及 Recovery 兩款小巧 reclocker Dear C Hing, have you tried inserting ifi power 9v into the Recovery? Ifi power said it's noise is 1uV.		SmokingMonkey 會員 218.xxx.xxx.184	2016-03-23 00:49

Eneloop batteries are better than other brands like Sony or GP, when fully charged 6 pieces total voltage keep at 8.4-8.5V pretty stable. After 10 hrs usage, it drops to app 7.5V still between the range of 6-9V required by RUR. Basically the performance of RUR did not drop much within this range, at least to my ears.

Spent some time having A/B comparison of Akaline battery and Eneloop Rechargeable battery. Eneloop Rechargeable sounds better, more transparent and better 3D space. I like it. It is more environmental friendly using rechargeable battery and better sound as well.

Done some study with battery. I think the impedance of battery make the difference.

I had tried A/B comparison of Panasonic Eneloop Rechargeable battery x 6 and Alkaline Battery x 6 (Duracell). Panasonic Eneloop Battery sounded much better.

Duracell is 181mOhm per cell. While Eneloop is 25mOhm.

For a 6 cells set up. Duracell is 1.086 ohm. While Eneloop is 0.15ohm. I think that make the difference. The noise level of battery should be similar for low power consumption. The impedance have the biggest influence in this A/B test. That is exactly what I want to learn with this experiment.

My view is that for digital circuit, the power internal resistance is key to performance. That will give a fast respond power source to support a fast “rise time” digital signal.

I'll also work on some experiment with choice of capacitor. Hope we could further improve it.

Created battery pack with 5 different capacitors (Electrolyte and Aluminum Organic Polymer). I like the improvement with these low ESR capacitors. Comparing them and now I know how they perform and what I like most.

Now we have a re-clocked USB digital audio using femto clock powered by battery pack coupled with low ESR capacitor.

Actually I created 7 of them and tested. Now I know better choice of capacitor.

Also compared battery (Alkaline battery vs Rechargeable battery - Panasonic envelop)

A "small" project:

Fanless PC with SSD (Running Daphile) =＞ W4S Recovery Reclocker (Battery Powered) =＞ DragonFly RED DAC (powered by USB which is regulated from battery pack input to reclocker)

Very nice sound.
