無聊上網見到 E 隻 Wyred4Sound 好似幾有趣...
唔知有無師兄試過...

Both Recover & Remedy are available to try out at showroom.  We have a lot of fun trying different power to get best output with the Femto Clock inside Recovery.  

Recovery supports 6V-9V DC power, so use of battery is not a problem.  When battery voltage drop after using for a while, it still within its input voltage optimal operation range.

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.
