Any experiences with FM Acoustics Preamps

I am interested to know whether FM Acoustics preamps - though technically specs perfect & meticulously executed have 'that emotional thing' we audiophiles look for? Or is it on the cool side.

Response from Forum members will be most appreciated. I'm considering the single-ended FM-155 to go along with the Symphonic-Line Kraft amp. Symphonic-Line recommends their RG3 MK4 as a perfect SS match or even their tube preamp Enlightment as a match. Nevertheless, FM Acoustics interests me but am not aware how it sounds & whether the integration will be perfect.

I just received my FM 245 preamp and it is amazing paired with a FM 411 mk2. I am very satisfied with regard to the build quality and sound. The difference in the sound quality was dramatic and noticeable right away. I have no experience with the FM 155, but I doubt you would be disappointed. Good luck.

The FM 155 is a very good preamplifier but pay attention to the high gain
One of my friends needs to let the -20db filter turned on with a Pass Aleph Amp

Coincidentally, I used an identical combo some years ago: a stereo Kraft with a 155 & later a 266. Both with excellent results, better than the RG3 & the tube one. The FM is hyper detailed and the Kraft is (reportedly) wide-bandwidth, so all is fine. I didn't find it cool -- but then my whole system isn't very cool anyway; it's on the warm side of neutral (i.e. 100Hz is higher than 10kHz). As a matter of fact, I slightly preferred the little 155 (but the reason is probably psychological).
Other pre's that did well with Symphonics are the old Goldmunds, and the CATs.

Hello Gregm:
In another thread, I read you mentioned - "I got a 'Kraft' class A and control it with a transformer volume. So, I still use SL amplfication!"

I would like to ask you that you went from RG3 with full PS, then to FM Acoustics & then to Transformer volume (passive). Why and what were your findings when you went from RG3 to FM and then transformer?

Also, as you used the FM with the Kraft, did you find he Gain of the FM acceptable or too much that you may have had to keep the -20dB attenuator pressed-in all the time?

Sorry for asking so many questions but the pricing of the S-L RG3 with Turbo PS and the FM-155 are practically as par so its very difficult making the choice. Technically, it seems the FM preamps are a notch above their power amps and this interests me to look into their pre for a perfect match with the Kraft.
