Yes I had the BS with a Yamaha wxa50 and it was very meh. I bought the FS when I moved and had a lyngdorf 1120 at the time. That was better but honestly I still somewhat more would be better. Got a NAD c399 now and I’m happy with the power, I still like the lyngdorf for all it’s software control and room perfect software.I just bought a set of these speakers, my first speaker purchase since before kids (empty nest now!). I’m still working out power, but they seem like they really need some juice. Does anybody else feel the same?
