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

I use the Yeti 400 for the whole system...the front end components are hardwired into the inverter and I plug the power amp into it with a connector.......that is why I could not do the full system on both.  Who would A/B a $400 all in one with a $2800 giant Gaindel system?  No one.  As I have stated over and over again.......the Yeti 3000 was beaten by the Ecoflow Pro which was annihilated by the Gaindel system.  I have no idea how the Yeti 400 compares and who cares.....it is too small to use for most people and has a noisey fan (which I made silent by removing most all the casing).  My friend uses the Giandel sytem and used the Yeti and Ecoflow on his entire system.  Get out of your head!!!!  Just do it!!!!!

The Entech will tell you something but not much.  People are already modding the Puritan 156 (which would not even measure with the Entech). and getting better sound (and that better sound has NOTHING to do with a measurement).  We are talking better jacks, better wires and Fo-Q treatment.  I will be installing burned in Furutech outlets and inlet and better wire on my friends Puritan 156 next Wed.  Most things that make for better sound CANNOT be measured.  An inverter that measures lower with the Entech may sound way worse than one that measures better......this game is complicated.

Why not use a 36 or 48 V battery and connect it directly to your amp's internal diode bridge rectifier, bypassing all troubles from 110/240V, inverters and what have you? It'll be a lot cleaner, and cheaper.

@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
