New Dedicated Line - Almost No improvement

I have battery storage device I tried on various components, prefer sound from dedicated lines and transformer based power conditioner. The cheap inverters in these devices is the problem, create their own noise/distortions. I assume those built specifically for audio, like the Stromtank have paid much attention to inverter produced noise.

It is this kind of audiophile sh-t that drives me nuts. All you have to do is buy equipment that has audiophile nut proof power supplies and you do not have to worry about anything except maybe lightening storms.

As for running components with battery supplies. I had NEW (Nirvana Electronic Works) DCA66 class a ss amp way back in 90's, early 2000's, ran off four wheelchair batteries, also have Merlin VSM-MM which has BAM that runs off 4 9V batteries.

Point is technology and implementation has been around for some time. Is it game changer? Based on my experience, no, and wouldn't you think audio manufacturers would have caught onto this if it was. Perhaps more battery storage devices with audiophile quality inverters will come to market in coming years, we'll see.

@theaudioamp Just pulling "isn't that against the code" out of thin air isn't helpful for anybody.  No, it is not against the code. There are a lot of 240 appliances that need outlets.  My home had 3 different 240 outlets for different appliances.  There are codes that govern the installation.

But you did hit on one of the big problems with battery systems--the cheap inverters they use.  The inverters for most commercial battery systems produce little more than a square wave.  They would be a huge step backwards.   One reason power regenerators are so expensive, the main reason, is that an inverter that makes a perfect sine wave is very expensive.  In fact, I don't know where to buy one except in an audio market power regenerator.

And I see mention of rhodium like it is the latest supermetal.  Shows how eager people are to jump on a buzzword.  Rhodium is a poor conductor of electricity and has no place in audiophile electronics.  

@carsbad. Pure sine wave inverters are not very expensive at all really. I can buy a 1000W unit out of Asia that will produce a fairly accurate sine wave for < $100. They are a dime a dozen on Amazon, Alibaba, etc. At light loads they produce good sine waves. At heavy loads there is some distortion. I even quickly found a DIY link for a 1KW pure sine wave based on old technology. The person built it for <$50 of parts. Probably not much of a market for those big old transformers so they are cheap.

Rhodium is an adequate conductor of electricity for a coating that is 10-20um. You would need very good equipment to measure the resistance of a coating that thin. It is poor because it is very hard.

You can’t install 240 outlets willy nilly. The NEC is written to prevent that. They can only be legally installed to support a device that requires that level of power (not voltage). Those appliances you have have 240V outlets because they require the power that 240V can deliver. It is NEC 210.6 (in complete) that specifies this.
