Stereomojo has reviewed the Coincident Speaker Technology Frankenstein 300B monoblocks ($5,499/pair).
These are single ended triode designs (photo) with self-biasing circuits and 8 watts of power. Each one is “hand built and hard wired in Canada.”
Reviewer James L. Darby thought the “Franks” were extra sensitive to tube choice, and used his KR300B for most of the review. As for the sound, he writes:
…the combination of the Coincident Super Victory speakers and the Coincident Frankenstein 300B monoblock amplifiers is not the best I have ever heard. However, among the many systems I have had the pleasure of evaluating in my home, there has never been a system that more accurately portrayed not only the musical detail in a recording, but also the feeling, soul, emotion and spirit of the performance.
Check out the full review, and try to ignore the typos and necrophilia references (I’m not joking).
