Hi Meby; The SF Power 1 would not be a "foolish" purchase, and Sonic Frontiers is not totally out of the "tube business". They are temporarily not producing new product-- as I understand it, but could re-start if they want to. They have temporarily shifted their emphasis to AV equipment.
I just sent my SF Line 2 tube pre-amp to them for upgrade to the SE level, and had no trouble making the arrangements.
About a year ago I bought a Power 2 and listened with it for 30 days (and I think the Power 1 has a very similar sonic signature-- just 1/2 the power), and you're right-- these amps are pretty neutral rather than "tubey" or euphonic. The Power 2 has a very smooth and nice mid-range and low treble, and was very non-fatiguing, but it did not have good bass control or articulation like a good SS amp has-- although bass was plenty deep. When I put my McCormack DNA2DX (300wpc) back in my system, I definitely preferred the McCormack and sold the Power 2-- but then I listen to a lot of hard driving R&R and rhythmic music.
If you really want a good tube amp, the SFs are smooth, liquid, and non-fatiging, and are good amps. Personally, I'd call SF and ask them about their capability to service their existing products-- ask for Frank Pugliano, Tech Rep. Good Luck. Craig
