Post Subject: Mine is microprocessor controlledPosted by Antonio J. on: 12/6/2007
You can find a brief description here: http://www.salicru.es/index.php?id=1678&L=2 My unit is a RE-1009 2T, which means has double transformer, but it's not the extra noise filtering model which they call NS. Looking at this I'm quite sure it doesn't regenerate a 50Hz sinewave.
When I bought it I was using a SS power amplifier which was DC coupled, so the DC offset due to the voltage swings on the preamp, caused the woofers to move back and forth like bewitched. Sometimes it even caused the power amp to get into protection mode. The stabilizer solved this issue perfectly. Now I'm using different gear, then the stabilizer is not really as necessary as it was then, but since I don't find any shortcomings that I can blame on it (remember I'm not a knowledgeable listener nor my system has the resolving capabilities others have), I keep using it. Still I can notice when electricity is in a good or a bad day.
I believe that a good regenerator that keeps voltage stable, decouples system from the grid and delivers a pure sinewave no matter what load you put in it, would be a very interesting thing to try. But all those devices are expensive and I really can't afford a trial and error merry-go-round to fix the power issues. As a toy the Kemp looks fun, those frequency and crest factor controls suggest that one could find a good working point to take the system's performance somewhere else. Deciding if that somewhere is any worth is completely another matter. Though I suspect it's not transparent to good electricity from the outlet if any different point than 50Hz (60Hz in US), 0% crest factor is used. The 75w top power is also a big shortcoming, if I spend more than 1500 euros in a power regenerator I'd like to be able to use it for the whole system. Another feature that I find questionable is the balanced power thing. Audio circuits have a common leg which shouldn't carry any active signal other than the one generated by the own device. Why using it to get half of the voltage you need?
The APS would be more interesting, but those reliability issues, the chance that sound results aren't the expected ones, and being the manufacturer in the USA and myself in Europe, makes it an uncertain choice. Moreover a unit for European market is different from a unit for the US, who knows how it would behave here.
I tried a PS Audio and I didn't like the results. Kind of trendy fashionable hifi sound that many acquaintancies I have over here do like. Haven't tried any other regenerator, then my experience is very limited.
