I tried a Benchmark HDR, but preferred the 840C, mainly for the fuller midbass (cellos and basses). To be honest, I didn't put many hours on it, so someone could always say I didn't break it in, but it was pretty clear that the midbass wasn't magically going to fill in with practice.
I tried it going directly into both my BAT VK-250 and Bryston 3B-SST, and also into my BAT 3iX pre-amp in fixed mode. The midrange of the Benchmark was excellent, though; very pure, like a good MM cartridge. And the highs were more extended. Really a very fine and flexible product if you prefer a relatively leaner sound. By the way, they are now shipping a much nicer remotes than the one you see on the web.
