dna2505,
Both the Sims and the Brystons suffer from the typical solid state bugaboos. What they do well, they do VERY well indeed, but they rob the music of life by bleaching harmonic color. The JC-1s do this to a much smaller degree, to the point where it's only just noticeable. Oh, and by the way, the JC-1s have both RCA and balanced inputs.
