Hey Odyofael; I used my Custom Bottlehead 2A3 amp with Louis' Omega Super 5's and found the 3.5 watts plenty for those Omegas. Since Clark & Molly delivered my Orca/BUF Sub loudspeakers, I have had those in my main system. I am guessing that unless you listen really loud, they will perform just fine on your Stereomour amp. It is basically the same circuit as mine____ just more exotic iron/cobalt inside.
Cheers, Hank
