I'm Dave.
Dilemna time
I've done some tests on A123 cells and they seem close to ideal as a power source. I cannot test the noise performance but output impedance and load transient response is "more than adequate".
I lashed 6 cells together to provide +/-10V for my active crossover and had a listen. The resulting sound is boring and bland. Where did all the dynamics go???
Now, I admit that I didn't remove all the decoupling as some are prescribing. But I've been through decoupling experiments with this kit before and as far as I'm concerned the standard engineering method (local small electrolytics with reasonable ESR and a 0.1uF ceramic as close to the load as possible) works and sounds best.
Once again I find I'm alone in my conclusions.
Actually I'm OK with that. My system only has to please me.
I've put my name down for the GB for al Ian's battery powered stuff and I don't know whether or not to bottle it now
