Atma-sphere S-30, any users out there?

Thanks for the feedback everyone, I am indeed intrigued with these amplifiers, however even at 30watts I think its too much power(my new speakers are 99db efficient) so I don't think I would be interested in the M60's- even with resale kept in mind. I keep leaning towards low wattage SET's, a lot of folks say that the first watt is the most important on a speaker like this, there is also a purity to the sound that would be nice, even with rolled off bass. As usual it seems clear I have not a clue what I actually want! For the price of the S30 I may just pick one up and try it, they seem quite affordable.

Nealhood- I do have the db99 speakers and really enjoy them, they sound good even with poor quality amplification. They sound great with good amplification, they can also be dialed into the room very easily with the bass booster dial. They seem to do everything right and NOTHING wrong, they have a small foot print. Break-in was a little rough at times, but overall I can't complain about the sound at all, I am not sure how they would sound in a really big room(mine is 30x18- not set-up ideally, but very capable of producing good sound) or a really small room, but they are producing great music in this room. The bass is tight, fast, very accurate and articulate, the midrange blends very well with the tweeter and both are detailed and lively(but by no means in your face)- they even have some of the air I was affraid I was going to lose when I left the maggies. They do not have as much air as the maggies did(with out a doubt that speakers strength) but there is also a ribbon tweeter that will be coming out for the 99's this summer which I think will be the answer.

So tell me about the pass F1 I can't seem to find much information about them. That may be the amplifier for me!
