Anyone uses FM Acoustics 155 Preamp

Oooops, posted wrong models. Resolution 266 pre, Res. 411 power, was the combo I listened to. Sorry.

FM Acoustics! Lucky you. What advice R U seeking?

Having only auditioned FM, I don't know if I qualify to post-- but here goes. I listened to, and loved, a full FM set driving Tannoy 12s (150 amps, I THINK your pre). Transparency, speed, and accuracy: top-notch, IMO stretching the speaker's limits -- or those of my cdp. HOWEVER, the sound was "different" from what I was used to, even on very familiar matl. It felt like I had more time to listen to small details and nuances in the sound, either harmonics (classical) or touches in the production (rock) -- e.g. discovering that what was a one-note electric guitar sound falling to the background actually changed note as it fell to the b/ground...etc.

Remember, this was a full FM rig; I assume the pre will mate well with yr Alephs, but cannot be sure.

FM Acoustics is reputed to "start where others peak", i.e., their entry-level allegedly compares with others' top of the line -- this includes pricing, too! On the latter, I assume you have listened to this unit? Can you do so with the Alephs? Just to avoid unnecessary investment!

Cheers!
