You had mentioned the dry cells before but I was unaware of them.
I went with the LiFePo the fellow recommended. I had ordered it before you posted this.
The key is depth of discharge and I am not sure if they are specifying this. All of their specifications seem to be in their own lingo.
Says it is ostensibly a traditional battery which leads me to think I would be in the same position i am already.
From what I can surmise a LiFePo will continue to play twice as long as the traditional battery since it can maintain over 12 volts almost to the point of being completely drained and being completely drained does not harm it.
Obviously the PUREPOWER and STROMTANK use two smaller LiFePo and run one while the other charges and then switches when that battery is down to its minimum. This is very clever but with the charger always in operation I would think this must add noise and that switch for the two batteries has to carry a sonic penalty since every switch does in my experience.
The LiFePos will arrive next week. I look forward to getting tired of listening.
I did listen with the charger connected and there is extra noise but one could live with it temporarily. I figure it is better to retain the use of the charger with the batteries fully charged so the batteries behave as big capacitors instead of the charger becoming half of the power supply.
I am wondering if there is any benefit to powering SMPS with inverter AC? I had my music computer connected and then thought I would reconnect it to the line to save on power usage and I think I may have heard a slight difference. As usual in audio the differences went in both directions for different aspects.
This is not a typical ATX supply but a massive MEANWELL 20 volts smps powering DC-DC converters from HDPLEX whose me - much better than even the best ATX - driving a MUTEC MC3+USB (USB to AES EBU) which is also now plugged into the LINE since it also contains an SMPS. Just curious if such mundane things had ever crossed your mind. If you use a computer for music files and preferably using WTF as your player - the ultimate minimalist player - the MUTEC will amaze you what is possible with computer audio. Sorry to have got so completely off of the subject.
