Well I am the newest person on the waiting list for the Rachael. Steve was nice enough to spend 30mins discussing my situation and what to expect w/ the Rachael based on my set up, 11'X13' room w/ Paradigm studio 80v2 w/ specs of 92db, 8ohm fed by a Csp2. Currently my amp is a SS 175 watts per chan.
I received a nice education on, I guess listening habits in terms of volume level. Basically the volume with which one feels is where the sound quality reaches its peak in terms of fullness/tonality etc is different btwn his amps and high power SS amps. I told him I like to listen at slightly higher than avg levels as then the music opens up. He said that is due to many SS amps sounding anemic until the volume is pretty loud, i.e. if 2 people sat on a couch, and the music was sounding right, we'd have to raise our voices quite a bit to converse.
W/ the Rachael, the music will sound full and perfect at a much lower level, so i'll not even notice that it's not as loud as I normally would like it to be. And, I won't miss the extra volume the SS amp has, at least with serious listening.
So even tho Rachael is not gonna get near concert levels w/ my speakers, it won't need to. Plus, this doesn't even take into consideration the improvements in musicality and transparency I should w/ the tune amp.
Never the less tho, he did say he will be expecting a call from me in a year or so inquiring about buying a set of his (more) efficient speakers. At which point, I'll really know the definition of kick ass sound.

I can't wait. I did ask about the Jupiter caps and he said he highly recommended them, and let me have them at the same price as the V-caps. Said more transparent and organic than the standard caps they use, and he prefers them to the V's. Will sound great w/ my Csp2 pre. I don't need the volume control option on the amp because my csp2 has the 2 gain dials which essentially would serve the same purpose.
I know this info won't be surprising for you veteran Decware users, but for new csr's like me with little to no experience w/ the Decware amp sound, maybe this will answer some questions.
