Using battery power to go off the City's power grid

@mijostyn - I’m sure those Atma-Sphere MA-2 monos are going to be incredible with the SoundLabs. A number of years ago, I heard the Majestic 845s paired with an earlier version of the MA2s and a Micro Seiki RX-5000/RY-5500 (I forget the tonearm & cartridge) it was fantastic! One of the top 5 systems I’ve ever heard. 

@sbayne  - My system doesn't use much power.  Just checked using the kill-a-watt monitor, and at 75db, my system uses about 90 watts.  I only have 3 components: amp, dac, streamer.

The two b300 batteries provide 6000kWh of power.  I can run the stereo for a couple days off it.  Recharging it via 120v will take 3-4 hours.  But, I'm putting a few solar panels on the roof, which will charge it daily.  I guess that will be a listening test as well - with the batteries being charged, does the sound change?

That 90 watts is without the internet router running off the Bluetti.  Which reminds me - I need to do a listening test with the router on the Bluetti as well.  But, I use both the Gigafoil and Network Acoustics ENO for filtering, so maybe I won't notice. much with that change.

I see you use the new MUON filter.  I'm going to try it.

I'll add that not only does the bluetti provide a darker background, it also increases the realism of the sound.  More organic and natural, with more presence - which is what I strive for in my system.  My DAC has those characteristics, and running off the Bluetti bumps that up a bit.

@veroguy - Ok, makes sense why the fan doesn't kick-on for over 4 hours of use -  90 watts is nothing for the AC300/B300. Yep, the MUON is excellent. I went with a linear power supply for my router and was surprised with the improvement in sound quality. Great idea to run your router off the Bluetti.

The owner of the property I live on has a Bluetti AC300 that is about 25 feet from me right now......so, he is going to bring it in sometime soon and I will a/b with my Goal Zero Yeti 400. The only thing the Goal Zero does negative is that the bass is not as good as the wall AC (when I run the amp on it). This makes sense as the output impedance of such a small inverter is not very low. If the Bluetti sounds in the league with the Goal Zero but has better bass....that is nice. However, my friend with the Giandel system first started with a Goal Zero Yeti 3000 which was sonically surpassed by the EcoFlo pro......which was then completely blown away by the Gaindel 5000/2 200 amp hour LIfePo4 system he has now. My guess is that any all in one will not perform at the level of a great separate inverter.......we shall see....errr hear.

BTW.....the PS Audio Regenerators do not use an inverter......they take the AC wall power and convert it to DC just like any power amp....and then create a sine wave and amplify the sine wave with an AMPLIFIER.......same as any amp running on AC..

Purepower regenerators do use an inverter.......but run off the wall AC......they convert to DC and then back to AC via the inverter.......PS Audio uses a power amp.

ricevs - That is going to be VERY interesting.
