Post Subject: More a matter of "efficiency", perhaps?Posted by Paul S on: 1/25/2008
Zipping casually through the PS Audio blurbs on the "new" unit, it seemed like they were basically touting the idea of greater efficiency (vs. the previous unit) and concommitment greater available power, along with finally coupling inter-component isolation along with the regeneration in one unit. I am guessing by the price that the "new" unit is also - serendipitously - cheaper to make; either that or competition and/or dwindling sales are turning up the heat.
I am not sure if the amp itself in the thing is "proprietary" or whether they just want to speak of it as though it is. They state in an "interesting" way that it is not Class D, but the decrease in size suggests that they must be using some variation on the old frequency-related switcher-oo, to keep tranny size down. If their numbers are good, it is pretty efficient, for whatever that's worth.
In any case, these guys never discuss the sound itself directly; rather, they cite the problems and claim the cures or they simply use nice descriptions to suggest bliss with use.
But then, I have never seen/heard outside this forum any discussion of AC that took into account my own related experiences. Everybody else seems delighted with the "blacker background" and "wider soundstage" and/or simply sold on a particular idea, never mind results.
Any readers who have tried this thing, please jump in before I repeat Romy's previous post with this product's name in place of the iso-trafo.
