David, I think yours is the first account I ever read, where a ZYX Airy 3 owner said the cartridge was flat, lifeless, and lacking dynamics.
Not that I'm disbelieving, as there may have been some reason such as poor synergy, non-optimal phono stage settings, set up, etc. Or a bad, or sub optimal cartridge?
Was it the X, or S Model?
I have owned the Benz Ruby 3, and now currently, the Airy 3. The Ruby 3 was a very nice cartridge. It did give a very nice pure lush midrage, sound was very good top to bottom. Nothing seemed at all to be missing from the sound.
A cartridge that produced music that one could listen without fatigue for hours.
Then on a whim, I decided to try the Airy 3X SB.
Off came the Ruby 3, on went the Airy 3. Both were aligned with the MintLP Protractor, so no differences as for alignment between the two.
Although the Benz was no slouch, the ZYX just seemed head and shoulders above the Ruby 3 in many ways. More dynamic, lighting fast, more clarity, and a darker background, with much less groove noise. I could go one, and on, but I'll save the lengthy descriptions.
Conclusion was, I had no desire to throw the Ruby 3 back on. Both Cartridges BTW, were both brand new, not used, both running through the Sutherland PhD Phono Stage, which was set at 60db gain, 1000 ohms for the Ruby 3, and 62db gain, and 100 ohms for the Airy 3.
The only issues I noted with the Airy 3 as it was beginning to break in, it did seem a bit mechanical sounding at first, and was also noting sibilance, and slight mistracking on certain transients.
The sibilance-mistracking was caused by me, in that I mistakenly followed some archived audiogon suggestions of optimal tracking force (VTF), and was tracking too light, at 1.86g. Raising VTF to an even 2.00g.
The mechanical "CD like" sound it first seemed to display with the first 0-20 hours began to smooth out as more hours were accumilated on the Cartridge.
As for the Benz LP, vs Airy 3, I cannot comment about how the two would fare in a shootout, and I suspect the Benz LP "should sound as glorious as its price commands".
Still, I would like to believe the Airy 3 would not be "embarassly shamed" by huge "night and day" differences, even in a shootout with the flagship Benz Cartridge.
My Airy 3X won't be going anywhere anytime soon, provided some dumb mishap doesn't harm its life. Mark
