Personally, I didn't care for it - while it fulfilled its hi-fi promises, I felt it compromised the soul of the original 103, creating something entirely different which was not to my liking. Also, the resonance match was not the best on my Triplanar - despite my best efforts, I couldn't get rid of the shimmy (especially at the beginning of the side where warps accentuate the issue). The usual disclaimers apply.
