To be honest I need a new tonearm so it might be another year before I consider a generator, never mind.
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?

@viber6 Thanks for telling me about the Tweak Audio Inverter Power article. That was a huge help, now I have some idea of what people are talking about. First however, I need a new tonearm for a Thorens that I’ve been modifying into a dedicated mono table that will out perform a Linn LP12. After that project, an entry level battery system will be the newest priority. As you know with this hobby, it never ends. As for my ASR Emitter II Exclusive, it is a beautiful sounding amp. The battery has six lead acid gel batteries that need replacing about every ten years. I’ve replaced mine once so far. The two power supplies charge the battery and the amplifier has a particular setting for the charge while the amp is turned off. No special power cables for the power supplies and battery are needed, just those that came with the amp. It’s recommended to charge the battery about every three days if listening every day. As for the ASR’s sound, it has a fully fleshed out presentation with a full dynamic range. It’s clear and musical with a black noise floor and a very wide soundstage. A harpsichord might sound as if it’s nine feet long however that’s the only time I might question the representation. It’s never taxing but it’s never artificial sounding. My digital and analogue rigs are simply plugged into a passive PS Audio line conditioner while implementing Akiko Audio tuning sticks. There’s nothing objectionable about the sound. There’s always room for improvement but I’m in pretty good shape. I also need a better power cable for my DAC and on the note, upgrades happen rather slowly. |
