1. Romy: have in the past gone to many studios and shows, including CES, Munich, New York, etc., and found only one studio where the sound was always very listenable: The Listening Studio in Boston. But of course you probably already knew that. Otherwise I’ve never heard a system close to hat you and I have obtained with primarily time, sweat, and 50 to 100 year old technology updated with a couple of the best present day equipment.

Not sure if I mentioned this before, in my solar/battery system, which is similar to Bills, sound is best at night when there is no sun and the inverter is drawing only from the batteries,)
I have noticed a slight difference in sound, but only later at night, after about an hour after sunset. Interestingly, the other night I ran out of battery power in the middle of a listening session, but didn't notice any difference. As the line cannot recharge the battery, am not sure why there has been such a change from prior to the solar in my system.

I already see another big time reviewer reading above, calling his body and say him hey; do you want to start a new company? You buy in bulk for penny the Chinese regenerators with batteries, and I will sell to my audio morons with my prices.)
One company seems to have come close. In the latest Stereophile, they review a unit from Astro tank from Germany that costs as much as my entire solar installation. They did give a fair review even though they had two defective units wit intermittent hum and even two detached high voltage lines. Caveat Emptor!
4.Amir: do have several 2 and 3 kva transformers inthe attic from previous trials about 30 years ago but have not used them since. I have removed the purepower pp2000 from the system as it didn't seem to do anything to the sound since the solar installation.p
As an ademdum, I did add one piece of equipment just before the solar installation that did a great improvement in noise floor and a mild transformer hum: Tai Heng Power Enhancer. Will be taking it over to Romy's later this week to see if it does on his system what it did on mine. For about $1300.00 from Vinshine Audio, was well worth it.
