Dan Schwartz has posted a review of the SST Thoebe II preamplifier ($3500) and Son of Ampzilla power amplifier ($3500) at Positive Feedback. His conclusions:
“The Theobe II preamp does everything you expect from a contemporary preamp, and (as reviewed) throws in a phono stage and DAC. Plus, in my opinion, it looks really good to boot….The Son never encountered the slightest problem putting out what the Thoebe (or the Levinson) threw at it, whether LP, digital or FM. It did nothing wrong, and always sounded transparent and excellent. ”
