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

@rudyb This is exactly what my N.E.W. DCA66 class A ss amp did, and this all back in late 90's!  It was nice to have an off the shelf all in one package offering, thought I would have seen more offerings in such a package over the years.

ricevs,

I still don’t know what you mean when you say the Amperetime/Giandel is "better" than the Yeti and Ecoflow. To me, "better" means more clarity/resolution in the entire freq range, but to euphonically oriented listeners, "better" means warmer and rolled off, etc.  If you say the Goal Zero sounds a little soft compared to the Bluetti you tried, I would probably prefer the Bluetti.  You say the Bluetti is "zippy" compared to the Goal Zero, but Bluetti owners here have not found them to be "zippy."  More advanced Bluetti options put them in a similar price range as A-time/Giandel.  Did your friend A/B these Bluetti's to his present A-time/Giandel?

This discussion is not at all like a typical discussion coming from Jay, where he claims that expensive invariably means better.  We are out to find battery/inverter solutions at 5-10% of the price of the Stromtank 5000, the only S-tank unit which can handle an entire high power system.  If Tom Lyle found the Goal Zero Yeti 400 sounded identical to the Stromtank 2500, that implies that the S2500 is a little soft, like the Yeti 400.  Is the A-time/Giandel more like the Bluetti for resolution at all freq?

Again with the clarity/resolution verus warmer/rolled off addiction game. It is not one game....It is not one way.....

You will only know what better is by trying one and listening......then you will know.. I can tell you a bunch of words (you like words) but words are not experience. When you get your Giandel (maybe in few years of talking about something you know nothing about).....and you listen.....ONLY then will you know what "better" is......but then again, you might find it "worse".....and this is why you need such hand holding.........."That jump off the curb really is small" says your mother....."I will even hold your hand." God, life, your mother, all of us are holding your hand. You will be safe. Trust the universe....trust your experience....but in order to have experience.....you have to JUMP!

So when is your Giandel arriving so you can listen and tell everyone what you hear? Or, are you just going to keep asking questions and making comments? Do you really want to know something? Knowledge is experience. I can describe the taste of chocolate all day long and you would still know nothing......You put a small piece in your mouth and you instantly KNOW..

Here are some words you all might like: The guy Oeno is the guy with the Giandel system....please read his comments: especially posts #56 and #61 on the next page

ricevs,

Please just answer my simple questions.  I know how to interpret your direct answers.  If you tell me that the Giandel is a soft sound like the Yeti, I won't waste even $2K trying it out.  I am perfectly happy with my present system not to bother with the extra considerable floor space requirements of batteries/inverter.

Don't school me on life, experience, etc.  My musical experience and knowledge exceed anyone you have ever met in your long life.  I respect your technical knowledge, so just answer my questions, please.

I'll read Oeno's account on WBF, thanks.

@ricevs Good that you can hear the failings of the interters you are testing.

About your comment on PS audio, I don't understand what you are saying or else you don't.  Inverting is changing DC to AC.  The PS audio rectifies the DC from teh wall and the converts it back to AC, the definition of an inverter.  

Are you trying to point out some other subtlty?  

But I say it is the quality of the inverter,  the quantity of amperage, and the low output impedance, that makes a quality power supply expensive.
