Nice system Balekan. Do you feel your 70/70 mk 3 has ample
power to drive your SF's. I had a 70/70 for a short time last
year. I felt as if they did not have ample power for my Vandersteen 5A's, which of course may generally be a tougher
load than yours. Certainly their efficiency is higher than
my 5's 87 DB. Please, everyone refrain from comments on how easy the 5A's are to drive. As with most medium efficiency
speakers, they enjoy some power IMO.
