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!

Your candidate list didn't mention the Shelter 501 II, which other threads note are superior to the Glider and to be preferred to the excellent Grado.

For what little it's worth as I don't have personal experience with any of these, I went with a Dynavector 20x high output and am quite happy as it has proven very smooth and not put out by an eclectic mix from one musical genre extreme to another.

Tim, the Shelter 501 will not fit his guidlines. It is very far from high compliance, low weight, and light tracking. In fact it is the total opposite.

You are in a rare catagory. Most people would consider your table (and arm) way below the other tables you mentioned, but because you understand the physics of how your table is supposed to work, you are able to make it sound considerably good.
I am just making a guess here- I don't know if any great high complience cartridges cartridges are being made that are going to compete with a similarly priced low complience cartridge with an apropriate arm, in that price range. I do know that with older tt's and low priced high complience cartridges, apprpriately set up, the results are laughably good considering what one can obtain them for.
I have tried low complience cart's on lightwieght arms, (the frog was one) and it just didn't work. Sure, it can sound ok, but you are right to question that route, as low complient cart's on that arm would be a waste of money.
I think that another appropriate question would be, is it possible for a high complience cartridge on a lightwieght arm to perform as well or close to a low complience cartridge on a heavier, stiffer arm, considering the technology you can buy in that price range.
I would say, good advice would be, be prepared to replace the arm. Since you are wise enough to search for a cart that is of the specs you are looking for, it seems wise to consider what arms you would be willing to buy in addition, to go with your new cart.

TWL and basement are correct.The low mass Thorens arm is a major limitation to suitable cartridge choices.You'll need to either replace the arm with a medium to high mass arm such as a Rega, PT, etc or select amoungst the higher compliance cartridges available such as the Shure V15, Grados,Goldring 1000 series(& it's DNM/Reson, Roksan Corus and Nottingham Tracer variants), Regas and Clearaudio Aurum MM's.Offhand I can't think of a suitable MC (but I could be overlooking some potential candidates).

Some more information. I just spoke with John Campas at Grado who said their carts are designed for tonearms with 10-15 grams of effective mass - my Thorens is 7.5g. He said all I have to do is put 3-5g of playdoh or putty in the headshell to get it in range. That sounded questionable as wouldn't a heavier cartridge accomplish the same thing??

Even so, Grados are quite a bit more compliant than nearly all MCs due to being a MM design, so this may be my best bet. A V15 may be the most trackable/compliant but I doubt the sound would be anywhere near a Grado Reference league.

So I guess my question becomes "are there any other high compliance MMs out there that sound truly Great?". Or: "My tonearm might not bring out 100% of a good $1K cartridge, but if I pay just some attention to compliance will it sound significantly better than my Ortofon?" 1700 mentions Clearaudio and Goldring I'll look into.

Basement, your take on my situation is on-the-mark: but it would be a whole lot easier to get a used Rega25 than to change my tonearm on the integrated Thorens, thus giving me modern materials and a proper arm and cart selection, losing me the semi-auto operation nobody seems to deem worthwhile anymore, for the extra $5 it would cost.

Finally, Bob_b et al, is there any reason to go with the 5mV Grado vs the 0.5mV Grado if I have a clean 60dB gain available? Dynamics, increased RF pickup, adj loading for a MC stage applied to a supposedly load-insensitive MM, resale value?? So many options, so little money...

Thanks for all your inputs.
