Wilson Sophia 89db 4 ohms and Audio Note Kits ?

Hi, i see this kits tube 300B Audio Note.
Could work well with wilson sophia-sasha (89db and 6ohms) ?
Manual sophia say: min. power req. 12watts.
and many kits audio note have PSE parallel 300B 18W

This 300B parallel is similar aprox to 60-70w ss amp ?

thank you and im sorry for my english.
No- this combination will be problematic. You need a speaker with about 10 db more efficiency to really hear what the amp can do.
I had Sophias listen to Ralph's knowledge/advice!!!!
