Switching to battery power

@goofyfoot 

Our AC mains is a 50Hz - 60Hz sine wave, so that's why the battery power stations are made to create them - to match the mains power.

If you feed your electronics a square wave or modified sign wave you may damage them. And if you don't, I'm sure your sound quality would be terrible. So a "pure wave" power station is the way to go.

Question is, just how pure is the pure wave? None of the battery power stations manufacturers publish that, so I'm going to have to roll the dice on that one.

To your point re wattage, I want at least 3 - 4 times higher continuous power output from the battery power plant than what my equipment will draw. 

pauly, please let us know how the EGO sounds.

@millercarbon,

how did you convert your Verus Rim Drive and what is involved? Sounds very intriguing. What weight is your platter?

I’ve done it before: fully off-grid battery powered audio system. At the moment, my preamps are the only thing on the grid when I’m playing music. Long story short - battery power done right can sound fantastically smooth and detailed. Where it seems to lack (unless you put a lot of effort into it) is with musical transients - like the smack of a kick drum. Right now I find myself enjoying classical music the most - the harmonics are so full and rich! I don’t seem to enjoy music as much that has extremely demanding transients. It’s a bit hard to explain because batteries have plenty of current capacity - I’ve accidentally melted copper wire before when wiring up batteries. I think it has to do with having too few amp-hours, the high internal resistance of the batteries, etc. It’s hard to compete with the grid in that regard. Sitting between 120 volts with megawatt size generators providing the voltage and current isn’t too shabby. I’ve got to wonder how large battery banks and/or capacitors/supercaps would sound.
