SME 20/2 SME V or Triplanar VII?


I'm in the process of acquiring an SME 20/2 and I would like to know others' thoughts and experiences with deciding whether to arm it with the SME V or the Triplanar VII.

SME? I cannot directly address your question, but would like to relate an experience I had about 8 to 10 years ago. I thought it relevant because some have recently noted that there CD rigs outperform their TT setups. I too think that my Ayre CX-7 is outperforming my Linn LP12 based LP playback system quite easily, though I am having power supply and cartridge issues.

At any rate, the SME 30/2 with their IV.VI arm is easily the best vinyl playback system I have ever heard. This is not to say that it is the best, just the best demo I have heard. It was at a stereo shop trying to sell the used SME setup for a customer who had gone all digital (fool). The shop had purchased a BPS cartridge an inexpensive Creek (or something like that - green lettering on front) phono amp just to demo the TT. The electronics were Krell KRC-HR pre and I think KAS amps (though it may have been KAS IIs' or FPB-600).

For the demo they used a gold CD version and a MFSL pressing of Muddy Waters "Folk Singer." The CD was played on Krell and Theta's best digital rigs of the time and went first. But as soon as the LP was started, we could only look at each other - totally blew away the CD rigs. Certainly my Linn, at least as currently configured, nor any of the VPI's, etc., that I have heard have approached that, even with more expensive cartridges and phono amps. Was this a fluke?
Another vote for the TriPlanar. As Nsgarch said, today's top cartridges respond to very precise adjustments in every parameter. Few arms can match the TriPlanar in its ability to optimize every aspect of setup. The better and more resolving the system, the more this will matter.

Gregadd is right that VTA-on-the-fly can compromise rigidity, but of course every tonearm is a bundle of compromises. The question for each of us is, "Which of the available compromises will have the fewest and smallest sonic negatives for me?"

The TriPlanar's potential lack of rigidity does not translate into any significant loss of dynamics or bass as far as I can tell. Its microdynamics and speed are better than any other arm we've heard. Before we chose the TriPlanar we demoed the Basis Vector, Graham 2.2, all three Schroeders and the SME V.

The SME V lacks easy, repeatable height adjustment. Since this adjustment varies with each record it must be set by listening. Having to cue the arm up and down while trying to find the right setting wouldn't work for me. Nor would I want an arm where I couldn't instantly return to a height known to be good for a particular LP. YMMV of course. If you don't easily hear the differences that VTA/SRA make, this won't matter much to you.

The SME V also lacks azimuth adjustment. This would be another non-starter for me. Cartridges are never perfect. Fine tuning azimuth for a cartridge is essential for achieving good stereo separation.

IIRC, the SME also lacks any real ability to adjust cartridge alignment angle. Again, cartridges aren't always perfect. Headshell holes instead of slots confer no sonic advantage, but they do make aligning an imperfect cartridge difficult or impossible.

The suggestion that an SME V might be more synergistic with an SME table sounds plausible, but what exactly does that mean? The only thing an armboard and plinth can do for a tonearm is provide a pathway for draining resonances. If the arm's design is such that few resonances reach the mounting plate, then this pathway is of little use. Perhaps the SME's one-piece armtube needs such a pathway. But the TriPlanar's armtube is thrice-decoupled from the mounting plate. Once by the azimuth yoke, once by the bearing tube yoke and once by the VTA tower. Resonances from the arm simply won't reach the armboard, so what "synergy" is there?

I'm not sure why Raul thinks a VTA mechanism needs a remote control to be useful. Mine works just fine, and I don't have to stop listening to music to use it! :-)

Thomasheisig's suggestion of the DaVinci was intriguing. I've never seen one, but the photos look very interesting.
Dear Doug: +++++ " I'm not sure why Raul thinks a VTA mechanism needs a remote control to be useful. Mine works just fine, and I don't have to stop listening to music to use it! :-) " +++++

Well, you have to stand-up and have to go where the tonearm is for you can change the VTA. A real VTA-on the fly is with a remote control where you ´can compare minute VTA changes in " real-time ": that's my approach.

Any one can do azymuth changes in the SME V, problem is that you don't know in deep those tonearms.

Regards and enjoy the music.

Thanks, everyone for your help. I am now leaning toward either the Triplanar or the Graham Phantom. Can anyone tell me where I might obtain an armboard for the 20/2 with Triplanar or alternatively the Phantom?

Dear Ed: Before you buy any tonearm my advise is that at the same time choose the phono cartridge, both items: tonearm/cartridge depend one each other and the better you matched the better the quality sound reproduction.

What do you have on mind about?

Regards and enjoy the music.
