My Phono Stage runs on batteries that charge only when the unit shuts down. Certainly, with such low signal levels there is a noise advantage and maybe a transient advantage. Doing a whole system based on a total of 4800 watts of Class A power is another story. It would take a large bank of lead acid batteries, a charging power supply that would have to be disconnected with use and a very big inverter. That is a lot of expensive stuff for minimal benefit. Good power supplies do not let much of anything through.
Using battery power to go off the City's power grid
I'm using a Bluetti AC200MAX 2,200 watt expandable power station to take my system off the city's power grid. It runs off a lithium ion phosphate battery with a 4,800 watt pure sine wave inverter. My total system only takes about 450 watts so I have never heard the fan kick on - it is totally silent. The music comes from a completely black background, with a huge soundstage that sounds very natural. I know that Ric Schultz has talked about these types of setups and there is a very expensive Stromtank battery system that is marketed to audiophiles. Anyone else tried this type of setup in their audio system?

@sbayne , Sorry, I have not yet updated my system page but the Phono stage is now a Channel D Seta L plus and I have a pair of Atma-Sphere MA 2's in construction as we speak. They are class A and I just checked, They burn 1600 watts at idle. They are going to run the Sound Labs and the JC 1s will do sub woofer duty. So the updated system will burn 3600 watts at idle. The current one will burn 4800 watt at full output. The QSC amps are running on 2 ohm loads. Why do I need that much power? There is no such thing as too much head room. It is wonderful to have a system that can drift along at 105 dB in effortless fashion. @theaudiomaniac , I may have stepped in it but the fact of the matter is that there are much better ways of improving the performance of your system than battery power supplies for line level equipment. I certainly will not be buying one as I do not have a noise issue. With all levels pegged I can not hear any noise at the listening position. There is nothing to gain. |
