Yes, EMI, is HF, yes. Why would you want to filter except for hf thrue mains? Just filtering for EMI?? Maybe build a Faraday cage??? I feel like investigated by the FBI. Ultracaps are COMPLETELY different from batteries. Ultracaps CAN have VERY low ESR values, while batteries mostly have very high internal resistance, except for LifePo4 (A123) which are low too, but not as low as some Maxwell 350F utracaps for example, they are 0,23 mOhm!!! Also, I am not aware of a battery that can charge AS FAST as discharge. There they differ A LOT from batteries. The Ultracaps used in my case, 100F ones, can deliver 11 amps constant current (AND YOU CAN CHARGE THEM WITH 11 Amps TOO), can deliver more then 60Amps pulse, and have a shorting current of 225 Amps. I really don't know what you are pointing to, and what you want to "PROVE" here, if your intention is to take me down with my design, go ahead. Feel free to bombard me with statements and questions, but I probably won't answer them anymore. Just for testcase, buy a few ultracaps, charge them to the correct voltage, connect them to your hq OCXO's or TCXO's in your high-end dac and start listening. Compare with LifePo4 and Shuntregs are superregs, and report back. ------------------------------------------------------------------------ abartels's Profile: http://forums.slimdevices.com/member.php?userid=65799 View this thread: http://forums.slimdevices.com/showthread.php?t=107352 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
