Never heard the SP-11 but IMO, it compares very favorably w most other top of line full-feature pre-amps. I would say that the phono stage is it's claim to fame- usually 2 or 3 phono inputs, MM & MC, w variable loading and full active gain, no SUT. Line stage is no slouch. No remote on mine and dual attenuators may be a turn-off to some, but it sounds great.
