Does anyone have information on Denon POA S1

higherfi is selling a pair right now. My buddy also own a pair and driving the Talon Firebird Diamond with BEST result. These are absolutely the most amazing SS amp out there.

I have owned the POA-S1 pair for about 5 years now and am absolutely mesmerized by them! Real warmth, liquidity with a tremendous bass control. These amps really need a 20amp circuit to come alive and run only moderately warm after 2-3 hours use. Extremely handsome and well made, I have not seen anything better or HEARD anything better so far. Note: I have not heard latest Krell EVO or PASS Labs and any other amps over $30K (e.g. like the silly 300k pair reviewed in S'phile) so take my statement with limitations. Due to space imitations and need to inc orporate the amps in a HT set-up I am running them with the Krell HTS 5.1 processor. I did hook them with the matching PRA-S1 and the sound was totally no-fatiguing and extremely transparent. The down side was the stack of gold finish units in middle of my theater room (2 huge POA-S1 and pre plus its power supply) which would reflect light off the screen when projector is in use. I strongly recommend these amps at nowadys used price of around $10K (+/- 1K) for those considering the Krells, Mark Levinson (latest are not good, try the 300 series) or Pass Labs. NOTE: I have no experience with tube amps.

I use a full S1 setup of transport DAC preamp,and the mono's in question.Totally liquid with fabulous detail, imaging,decay of sound at the end of notes is very evident,even when compared to top quality alternatives such as Accuphase Class A.Build quality is overwhelming,with massive size and weight.This is by no means a typical mass market Denon product but a specially made,reputedly by hand,range which takes the art of hifi manufacture to it's very limits.There are supposed to be only 47 pairs ever constructed,although I have been unable to substantiate this.
Unless space becomes a limiting factor these items are one of life's ultimate possessions,and their beauty of appearance and sound is something to keep forever-I certainly hope to keep mine.
Weight =79 kg per piece.
Finish =Champagne Gold
