B & W Matrix 801 S3 and tube amplifier


I cannot find an impedance graph for B & W 801 S3.. The manufacturer states min impedance of 4 ohm and recommends amp of at least 50W. I am wondering if a 60W tube amp such as Conrad Johnson MV 60 or Premier 11A would do the job for mostly low level listening in a small-mid size room. Does anybody have experience with similar combination ? Would ss Conrad Johnson amp be a much better match ?

i think technical work along with testing of technical work on various components is considered to be direct experience by definition and i didn't say that it won't work. it will only for a while.
Thanks everybody for the comments. I will focus my search on solid state amp(s). So far I have Simaudio Moon w5 on my radar and I am curious about CJ MF 2500A.. Parasound seams like a good suggestion (will have to do some reading on their models) .. Are Parasound amps reliable? Do they retain value over time ? Any other suggestion for a secondhand amp in approximately $1500 - $2500 price range that would go well with CJ PV 12 and B & W 801 S3 ?
Parasounds IME are very reliable which is probably why they have one of the strongest warranty's, 5 years parts and labor. Of all the brands that I have custom installed, other than possibly McIntosh, they give me the least problems.
PS- It is the Halo line from Parasound that IMO are an excellent match with 801's.
