Contrary to popular belief, the 1.6s don't need nearly as much power as the 3 series maggies. Actually, I found them to sound better with tubes. But you will need a good solid 100-150 watts of tube power, but the coherency and midrange you get will sound much better than an average SS behemoth. My RM-9 did a fine job with 1.6s, but was a total flop on 3.5s.
