Post Subject: Dedicated mains supply vs. PurePower2000iPosted by manisandher on: 3/25/2011

Well, my dedicated mains supply is now active. It took over 2 months to install because my electrician seems to have an aversion to working more than 1/2 an hour a day. But he loves hanging out at electrical supply stores... judging by the amount of time he apparently spent there rather than at my place.

So, a quick overview of the total system:
- 15KVA isolation transformer (sitting in basement) connected directly to the input of the house
- ionic grounding system (bonded to Neutral of isolation transformer secondary)
- 'star' grounding to all components

What amazed me immediately was how similar the new AC sounds to the PP2000 in battery mode - no 'shiny sheen' to the sound, very 'woody' and incredibly smooth. But the new AC has better dynamics - the battery sounds flatter and more 2D in comparison. But both have essentially the same character.

What is very obvious is that the new AC is substantially better than my PP2000 in regenerator mode.

I will try to sell my PP2000 and recoup as much money as I can. Failing this, I'll have a very expensive UPS for my work PC and NAS drive...

Mani.
