I have to admit, I debated posting about this as I don't really mean to stir the proverbial sh*t pot, but  . . . I was in contact with Clayton Shaw of Spatial Audio and I inquired about the sensitivity of his M5 speakers and if they were a good match with low-powered, SET tube amps. He first told me that 6 watts should be enough, provided the amp was of a high enough quality. Okay, so far so good, as I have a Decware SET in mind. Then he inquired as to what amp specifically I was looking to pair his speakers up with and I told him I was looking at The Rachael amp and he wrote back telling me to "see if I could get a return option on the amp" as he has a Decware amp from the early 2000s (he did not specify which one) and it didn't work well with any speaker he tried. Okay, on the one hand, I could understand if he would have said, "Decware amps don't seem to be a good match with my speakers" or some variation thereof, but, y'know, to say it didn't work well with any speaker he tried sort of made me chafe a bit. Now I know, a lot of subtlety can get lost in an email, and maybe he didn't mean to sound as uncharitable as he did, but man, it kind of came off that way. In any case, it was his speakers that I wrote off and not the Decware amp, which I am still in pursuit of acquiring.

Yeah, my Decware amp sounds fantastic with ALL speakers I've tried.  

I remember contacting the owner of the company at one point.  I am noit sure if I had mentioned the Decware name or not, but when I mentioned my amp was 2.3w per channel or so, he specifically said his speakers were good with at least 10w per channel, so mine would not be a good match.

We have been using this for several weeks now and it seems to be going nicely.
