Pepler,
I'm currently running 1sc with the Audio Note M6 preamp and Audio Note Quest Silver 300B monoblock. Don't be put off by the 9 watts output. There is no problem with dynamic whatsoever. The sound is really magical and gorgeous. I've not heard Soro driving 1sc though, but I would think it should produce good result. I think you must audition them before making the purchase.
