Using battery power to go off the City's power grid
ricevs, Too many variables between the compromised Bluetti AC200P and the Goal Zero Yeti 400 with its woodblocks and PPT.  I thought you were using the Yeti with your front end only, not with power amps.  The most meaningful A/B you can do is bet... 
Using battery power to go off the City's power grid
Actually, live unamplified bass in the appropriately sized room or hall is delightful because of the many harmonic overtones which go up to HF.  Take a French horn which has bass, although not as deep as a tuba.  James Boyk has an essay called "Li... 
Using battery power to go off the City's power grid
ricevs, I agree with much of what you just said.  My main question was about the bass from the Goal Zero.  Comparing to wall AC, Is it looser and fuller, in other words quantitatively greater but qualitatively worse as with old school tube amps? ...

mijostyn, There are certain audiophile buzzwords that are nebulous concepts with uncertain musical meaning.  "Noise" and "noise floor" are examples.  As a musician and music lover first, and audiophile last, I am interested in tone, resolution, c... 
Using battery power to go off the City's power grid
ricevs, When saying something is better, we should be more specific.  In general, sonic purity and accuracy is associated with more extended HF and tighter bass, among other things.  But the tighter bass is also less full.  If the Goal Zero is mo...

goofyfoot, Just read the posts by ricevs.  Look at his website, tweakaudio.  Click on the golden inverter button.  He notes his experience with Goal Zero, and his friend's better results with Amperetime batteries and battery charger, Giandel inve... 
Using battery power to go off the City's power grid
ricevs, I don't see the point of adding as much battery power as you like.  For example, your friend uses two Amperetime 200 amp-hr batteries.  At 12V, this is 4800 watt-hr if the batteries are fully charged.  His Giandel inverter is 5000 watt-hr...

Good points. I heard that hybrid car battery manufacturers are looking to replace lithium batteries which can overheat with some sort of new "solid state" technology I don’t know much about. How hot do your friend's dual Amperetime batteries get?  
Using battery power to go off the City's power grid
ricevs, Thanks for the comforting words.  However, the low level components could draw 1 (idle)-100 watts (loud music).  Without the battery charger, after 24 hours the battery would lose 24-2400 watt hours, with a dead battery unable to be recha... 
Using battery power to go off the City's power grid
Ricevs, Makes sense, thanks.  If the inverter is on all the time, but all the electronics plugged into it are off, then there is no current draw from the inverter.  So the batteries won't get drained.  But if the low power electronics like preamp...

sns, Good points.  From the international phone access code of 86, Giandel comes from Hong Kong.  I guess your Rockpal is the battery, so your procedure sounds logical.

Ricevs, You are absolutely medically correct about the importance of LOVE from your cardiologist.  It is important to have a technically competent cardiologist who has the needed experience in doing catheterizations, stents, but if you don't like... 
Using battery power to go off the City's power grid
Thanks, sbayne.  I am confused by the turn on procedure in the Giandel 5000 user manual.  It says to turn on your electronics first, and then the inverter.  But since the electronics are plugged into the inverter, when the latter is still off, the...

sns, Correct.  
Using battery power to go off the City's power grid
theaudioamp, Your entire lengthy post of 8/8 11 PM is FALSE.  In particular,  "No, any piece of equipment does not have a sound. This is Philelore and is not true." "And I personally know lots of people who believe stuff that is absolutely not ...
