The Glider comes in Lo(0.4), Hi or medium outputs. My Koetsu was rebuilt by Koetsu and unused,the Glider was a brand new one I had as a spare.
The Glider mounted on a Kuzma Stogi S/Oracle gave very little away to the Koetsu or ZYX but then oimo, the Gliders seem to mate particularly well with unipivots.
Certainly sounding a bit 'lighter/faster' than the Black.
Unfortunately lack of funds meant the Glider/Stogi S had to go which was a shame as for a vfm combo, it was an extremely capable pairing.
Never understood reviews suggesting the Gliders are cold as I always found them just a tad the warmer side of neutral, not by much but just enough to stop them sounding sterile/clinical.
On the zyx front, they are very light cartridges and the silver bases which add weight should be viewed as necessary rather than an option. They tend to work better in fairly high mass arms. Having J7 make additional/alternative weights for a wta, PU 3 & Kuzma Stogi S improved the sound in every case. The cantilever design also makes them a pure pig to clean as they seem to be a magnet for any dust on the records and it's not recommended to use any kind of fluid, so it's a two edged sword.
Well, this is salutary and worthwhile info., certainly as far as I'm concerned. Received wisdom is an imprecise form of learning, so back-up details of ancillary kit add hugely to this learning curve. However, using two effectively new cart's as an assessment tool is possibly questionable, as both cart's will exhibit different qualities as they are run in for thirty plus hours or so.
The Glider has, unfortunetely (for me), an output of about 0.6 mV (equates to 0.4 mV @ 3.54 cms/sec). About the same as the Black, many Transfigurations and Shelters.
When I recently reintroduced my Goldline to my A.A. 12" arm after getting used to a Urushi Vermilion (0.34 ish mV @5 cms/sec) my wife and I were initially knocked out by the gutsy, lively and encompassing sound which greeted us; the subtleties and musical nuances of the Urushi were temporarily forgotten. However, upping the volume control (on my NAP 552) brought an overly powerful presentation, negating the feisty benefits. Conversely, I can up my vol. control with the Urushi almost 'til the cows come home, improving dynamics with no downside.
This is, of course, somewhat affected by the phono stage (Superline/Supercap), which is technically up to 0.5mV (but with a large overload margin, of course). Balancing qualities of cart., phono stage and output, I'm now convinced, as many others are, of the superior musical benefits of a slightly lower output (though I draw the line at an IO
).
It does piss me off that so many cart's come with meaningless output figures, often omitting the standard against which they are measured (American etc. or British (European?)). 3.54 cms/sec. or 5 cms/sec.. Why this was not standardised donkey's years ago is beyond me.
