I heard SFs with both Art Audio and Audio Research and in my opinion, if you like the smooth sound, you'll not go far wrong with any tube provided you get a suitable matching power.
The only issue is the sensitivity - you may find the 18W SET will stuggle with 92dB / V.
I'm looking at the hybrid Lamm amps as my particular Wilsons are not so sensitive.
