I must have promised several times already that I'll take my old DCs into my dealer and compare to the i's. Why haven't I done this? No excuse. I beg Your Grace's indulgence. I will report back when it happens.
Also on the 'I-have vague-intentions-of-doing-this-but-no-guarantees' agenda: I'm supposed to take my DC's up to another dealer and hear them with the GamuT D200 and C2-R; except he no longer has them in the shop. But he does have a VTL 5.5 and ST-85, and I think a 100w ss amp from Accustic Arts in Germany.
Also, on the 'I-talked-about-this-once-but-it-will-never-happen' agenda: At my last listening party I threatened to bring my DC's over to hear in this guy's system: Bel Canto SET40's, nice Michelle tt, Herron pre, etc.
Oh. For what it's worth, I do hear high-frequency roughness in my system. I have determined that it is not my cd player (I sort of bought my way out of that problem--not recommended if you're on a budget), I've played with cables; I've heard my amp with other speakers, but I haven't heard other amps in my system. I remember hearing artifacts of the high-frequency prominence in the other systems I heard my DCs in before I bought them, but in my system with no pre-amp, a very clean amp (perhaps too much so), no crossover: the things that were hinted at before are just more audible.
