Only $15K, although you can probably use a smaller one depending on how much power your amp and turntable take, along with how long your record sessions last before needing a recharge.....and you have to have 48V components, using an inverter back to AC will just add a bunch of noise back to the power supplies.

No, not ideal, but there are other solutions out there, including one product which despite some early promise (along with the shares of the company), ultimately failed: ceramic fuel cells.

The only way a battery power supply would make any sense, is if the audio equipment was designed to run on DC power. There are only a few examples of DC preamps available, and I'm not sure about turntables. Battery powered A/D converters are readily available. It would be expensive, and no guarantee of any improvement over using conventional equipment. Using DC batteries for power and then converting to AC would be a complete waste of time and money.

Really, assuming that DC battery power will eliminate power line contamination is just that, an assumption and in my opinion totally unproven and probably wrong. I know for certain that my battery powered computer laptop headphone outlet sounds considerably more transparent, detailed and dynamic after midnight. Why would that be? It's not plugged into the mains outlet.

Also, from my experiments with vibration dampening on micro-components, I am certain that audio components and cables themselves are responsible for a great deal of the distortion assumed to be power line contamination. It seems likely that power line contamination enters the equipment from the atmosphere (passing traffic, machinery, household appliances, lighting, TV and radio broadcasts), via exposed nodes of metal acting as antennae, such as every single exposed, untreated solder point in an audio system. Of which there are usually hundreds, or even thousands.

Anyone who can hear the difference between BHQS11 and BHQS13, can hear the effect of controlling the influence of these antennae. But the internal components themselves also introduce thermal vibrations which smear and muddy the dynamics of the music.

Agreed about the DC supply not being either practical or necessarily an improvement, particularly after going through a DC to A/C converter. My only thought was to eliminating interference generated by other equipment plugged into the same electrical circuit. But if as you say, boss, what really counts is what happens within a metre of the equipment being fed, then perhaps it's not significant in comparison to other factors, such as those you raise above.

When you mentioned passing traffic, I immediately thought of mechanical vibration - passed through the ground and through the air - but in context to exposed wiring in the equipment, you obviously mean radio waves emanating from the ignition system? I can perhaps understand radio waves effecting electronic audio equipment, but mechanical vibration I can't, except to the extent that it may affect the stylus tracking through the record groove. Do you mean perhaps that the vibration of the equipment, and cables particularly, causes nano-scale voltage peaks caused by the ever so slight movement of wires through a magnetic field? Whether mechanical vibration or radio waves, I don't see how AVM could possibly prevent either effect. To work against mechanical vibration, the AVM would have to sit as a buffer between the part it was protecting and the source of vibration; therefore, if ground borne vibration, solely on the feet of the equipment or furniture; or if airborne, you'd think everything would move including the AVM. If it's radio interference that the AVM shields against, then how? my understanding is that only a metal shield will work.

Perhaps thermal vibration is the chief culprit, but doesn't hi-fi equipment sound best at "operating temperature"? Otherwise, you could use a cooling system to keep everything chilled for superb sound.

As for the battery powered headphones sounding better after midnight, maybe there's less ambient noise to interfere with your hearing, or maybe there's less airborne electromagnetic radiation because more equipment is turned off in the neighbourhood.

Just a couple of points Daniel - mechanical vibration has a very marked negative effect on the sound of electronic audio equipment. That fact can be easily verified by using conical tiptoes underneath a preamp or power amp. The tiptoes allow mechanical vibrations to drain out of the equipment and dissipate via the supporting table into the earth. Various metals and configurations will show different degrees of improvement, but even cheap plumbobs from a hardware store will work. Allowing mechanical vibrations to drain out of the chassis and therefore away from the internal components as well, has an immediate and dramatic positive effect on the sound quality, easily heard by anyone even on a cheap system. I assume you must be already using them? Tiptoes or spikes under the legs of the table supporting your audio equipment will give additional major benefits. It is best, if possible, to have each piece of audio equipment on its own table or stand with its own draining spikes, because vibrations from one piece of gear will audibly affect the performance of another. I personally don't do this because I like to have extremely short connecting wires. But if I could isolate the vibrations of the preamp from the vibrations of the turntable, there would be a marked improvement in the sound quality of both.

I don't know exactly how AVM works, but I know it works incredibly well. I assume the molecular or physical structure of the AVM absorbs micro-vibrations in a method that could be similar to (for example) a cup full of sand. Every time I have used AVM, it has resulted in an audible improvement in sound quality. Just painting a couple of circuit board solder points will show an immediate positive result (after 8 hours drying), which lasts forever. It's insane.

I was referring to all forms of electronic emissions and mechanical vibrations caused by passing traffic. The effect of these would vary depending on your location.

Yes, I see that I was thinking about mechanical vibration the wrong way around now (outside-in instead out inside-out). The physics of what causes it is beyond me however, unless it's related to the solenoid effect. I used to use conical feet on my equipment, but haven't had the opportunity to return to my old setup protocols for some time now.
