Cart update: old TT, new electronics


I've just significantly upgraded my system, but comparisons over the last year with my modded Thorens TD115 + Ortofon VMS20eMkII have shown it better than a Music Hall MMF7 or Planar25. I've had the TT and cart for 22 years and they make a great match: high compliance cart + low-mass tonearm. Replacement styli every few years. The TT has 10lbs inert clay in the base, a nice mat and clamp, good interconnects. I also have a 2nd TP-30 tonearm wand, and can easily drill through the top as needed for carts that can only accept screws from above (ie Grado woods).

But the signal chain is now a BelCanto Phono 1 (40, 54, 60dB gain), Sonic Frontiers Line1, McCormack DNA0.5 revB and recent Thiel 2.3, with good AQ ic/cabling. The Thiels have shown up the age of my cart. I'm doing a crash course in current carts that will be truly the next level beyond the Ortofon that has been so musically satisfying over the years. Even though the Thorens isn't the final word in modern TT design, I feel it's fine for allowing a new cart to perform well.

> reasonably high compliance, low weight, light tracking for the low-mass tonearm
> definitely NOT bright or forward because of my Thiels and preferences
> reasonably forgiving setup - tonearm has no VTA, all adjustments in headshell
> nothing too tweaky, hard-to-find or esoteric
> <<$1K used
> all the great sound qualities of modern carts incl solid articulate bass, rich mids, airy highs
> prefer not to have a very low output MC, the above criteria seem not to favor them anyway
> wide range of musical taste, but more rock-based than chamber music or new age

Candidates:
> Grado Reference, high or low output. What's not to like? Compliant, light, detailed, not bright, well-received.
> Benz Glider H2. Too bright? Too little compliance for arm? Too inexpensive? Better Benzes?
> Clearaudio Virtuoso. Not too much info but good company and great reviews, too heavy @ 10g.
> Ortofon Kontrapunkt a/b: too heavy, too bright, too bad.
> Van den Hul Frog: good luck finding one used.
> Shure V15 latest incarnation. Any better than my Ortofon??

Any and all useful input appreciated!

I am quite delighted with the Grado Statement Reference (mine is the low output 0.5mV model) list $1200, but I've heard that you can get one new for around $800. Can't help you with any other comparisons; I'm so happy with this that I've never even considered trying anything else. I use 60dB gain with mine. The preferred load is 47K-ohms, but I only have 10, 30, 100 ohm load options available at the higher gain settings (obviously intended for moving coils) so I use 100 ohms. Grado factory advises that the cart. is load-invarient but I really wonder about that claim. I'll have to get into my phono stage with a soldering iron in order to experiment.
Hi Scott - you guys are more knowledgable about these compatibility issues than I am; I'll gladly contribute within my experience though.
Grado is a hybrid design; not moving coil, but not moving magnet either. Grado calls them a moving iron, or variable reluctance design. Both the coils & the magnets are fixed within the cartridge body, the cantiliever actually moves around a very low mass (thus high compliant) piece of ferrous metal (iron) which disturbs the magnetic field between the magnets & the coils, thus producing audio output. If Grado's proposal to increase effective mass of the arm seems like a valid approach, then I would use the low output version of whatever cartridge model you chose. You have the required gain, so why not go with the sonically superior low-output version (fewer coil windings = superior performance). I believe that you would also be less prone to hum & noise pickup with fewer coil windings vs. more windings.
Regarding fixed VTA, try to set up the spacers such that the cart body is parallel to the record surface, or perhaps just slightly negative.
Scott I don't really know because my woofers are horn loaded & invisible unless the cabinets are opened. But the power meters don't move mcu unless I'm blasting of course.
