Switching to battery power

George, I find this post odd. To make the claim that lights are turning on and to not know what they are for. Trying to play the amp with an uncharged battery, etc... It's as though he's making up issues or he's not operating the amp in the way it's intended.

My ASR Emitter II Exclusive power amp runs off a battery that's charged by two power supplies. The sound is so clean that my other components are only filtered by a PS Audio passive line conditioner and some Akiko Audio tuning sticks. Milwaukee makes a lithium battery generator that produces a pure sign wave. Here's a review, https://audiophilestyle.com/forums/topic/60304-surprising-budget-audiophile-product/

I’ve never had a problem George and Herr Friedrich has been making ASR since the early 1980’s. It’s now at the tech because I have a signal cut in the right channel but this is the first time since I bought it that I’ve had repair work done.
Any views on the Milwaukee lithium generator?

For those who are looking at a no cost option, this unit seems to be a favorite. I still wonder how different it would be from the above mentioned Milwaukee MX.

pauly, why would the Goal Zero be preferred to over the Milwaukee?

pauly, please let us know how the EGO sounds.

pauly, I'm left wondering why a generator that produces a pure sign wave is an advantage? The Strom and the Milwaukee both produce a pure sign wave so I was thinking that the Milwaukee would be the best option. However my electricity at home doesn't produce any type of sound wave that I'm aware of. Also, you might consider the wattage of the unit and the possibility of the generator over heating. 
The EGO has a good price tag. It doesn't include the batteries. Four of those may end up costing you about $300.00. Which ever generator you buy, please let us know what you think.

pauly, that sounds great. I have my DAC, renderer, Quad 2905 ESL's, phono amp and turntable that I would like to power by a battery generator and the ECO is affordable.

I'm not sure how I would manage to keep my ESL's plugged in if connected to the battery.

I gotta find a way to use a battery generator but keep my Quad ESL's plugged into power 24/7. Any ideas?

pauly, It will be some time as my amp is still with the tech and that won't be cheap to get it back. I'll probably post something about it when the time comes. Anyway, happy listening!

All-right, thanks Pauly. I was thinking that but I wasn't sure.

pauly, I plan to try my digital front end and then my phono amp and turntable. I’ll try those first, plugged directly into the battery and then through the passive line conditioner. The ECO is affordable by comparison to the other generator’s and if it does the job of powering everything besides my amplifier, then I’ll be happy.
I can say the ASR that I own is highly thought of by many in the audio community and their flagship components consist of the larger amplifier, two power supplies and the battery. Purchasing the power supplies and battery is costly but it raises the bar sound wise. I do not doubt that your hearing a difference with your amp connected to the battery.  I believe that at some point, interchangeable, after market battery units specifically for audio equipment will be common place.

pauly, thanks for the update. I would most likely draw more power than you, having my ESL's plugged in. I'm guessing that the additional battery would be enough. This battery option seems simpler and it makes much more sense than a traditional power generator not to mention moe affordable.
