"These are not characteristics that I would ascribe to the Graham 2.2. Was your arm/cartridge properly set up?"
It was set up as well as we know how of course.
Last December we spent three days fine-tuning the blue goop, with the help of SirSpeedy's excellent advice. Four listeners confirmed the optimal level for each cartridge.
We adjusted azimuth by visually eyeballing each stylus to make sure it was vertical. Cello and I are co-owners of a Wally Analog Shop, which allows electronic measurement of azimuth, but IME I get nearly as close visually as I can with the Wally.
We roughed in VTF using a .01g digital scale and VTA by starting the cartridge level (which ZYX's prefer). We fine-tuned from there by listening. My partner Paul took the lead there, since he's more sensitive to VTA/SRA than anyone else we know.
We followed the same procedures with every other arm. IOW, we took as much care setting up the Graham as we took with the Schroeders or the TriPlanar. Yet the sonic characteristics of Cello's Graham have been evident on all four occasions that I've visited.
Perhaps there's something about setting up a 2.2 that neither Cello, Chris Brady, Frank Schroeder nor I understand. But none of us has been able to get it to perform at the level of even a Schroeder Model Two, never mind any of the higher priced competitors.
CB recently sent Cello and me a new drive belt. It's an experimental one that provides better platter-motor coupling than the old belt and thus superior resistance to stylus drag.
On my 320/TriPlanar/UNIverse the new belt is a 100% success. I had to increase VTF slightly to allow the stylus to track the more forcefully driven grooves. I had to adjust VTA slightly to compensate for the slightly higher downforce. Once I learned those adjustments the increase in dynamics and bass response was unalloyed by any downside.
On Cello's 340/Graham 2.2/UNIverse the new belt has resulted in some excessive brightness that he's been unable to tune away. Perhaps he hasn't spent enough time fine tuning VTF and VTA. Perhaps he needs another drop of blue goop. Or perhaps the Graham just can't handle the extra energy.
