Johnnyb, I couldn't have said it better.
"S" shaped tonearm ?
what is the reason a company ,such as denon for instance to put an "S" shaped tonearm on there table. ive had both straight and S . and while not high end , i currently have the denon dp500m table . ive heard nor seen an advantage to either, though my experience is very much amature audiophile.

Its a long way from the original question which was why were tone arms s shaped (paraphrasing). However, what this has evolved into is a discussion of one of the hobby's basic questions: Is design X better than design Y. Tubes better than SS, etc, etc. The answer is almost always, it depends. Depends on what? 1. How you define better? 2. How is the design implemented? 3. Is cost, convenience and/or durability a factor (see #1). 4. What associated equipment is involved? 5. What design decisions were made in the development of the associated equipment? These factors (at least 2-5, I'm sure there are more) are especially relevant with an LP playback system, since it consists of several different "modules", often sourced separately, that must work together. Cartridge, headshell (perhaps), wiring (perhaps), tonearm, platter, motor etc. In the real world it is very difficult to separate these factors out. And of course many of us define #1 very differently. This is endemic to any artform (I'm talking music, but perhaps that word also applies to TT design). The weight each individual places on each factor (and even the name and number of factors) varies and it is highly unlikely that any two persons would "evaluate" a musical experience identically. In the end, tho, I would argue that design implementation, manufacturing, quality control, and the other elements in the analog chain are more important than whether the arm is straight or curved. As several others have pointed out, not all carts will "work" in every arm and not every arm is right for every kind of table. However, its lots of fun to read and talk about this, so blog on!!! |
Jrw40:Now that this thread has beat tonearm design theory to death without answering your question, I'll make a stab at it. The two main turntables (that I can think of) that are using an S-shaped arm are the Denon 500M and the Technics SL12x0 variants. I can think of several reasons they might do this. * We've already established that to use a detachable Universal headshell on a 9" tonearm, there has to be a bend in it for better tracking angle. This means the wand will be a J or S shape. * In Japan, the home market for these manufacturers, the S-shaped tonearm and universal headshell are both still popular. E.g., Audio Technica still makes a J-shaped tonearm with detachable headshell for $1900. It's at AudioCubes II here. The detachable headshell thing is popular enough over there that ZYX offers a universal headshell at about $550. See it here. Technics and Denon have probably determined that offering a manual turntable with detachable headshell still has market viability. Being able to use a tonearm design from the '70s on a direct drive transport enables them to maintain a presence in the turntable market, offer higher build quality for a lower purchase price, and avoid R&D expenses on a market that currently can't generate the numbers they require to invest in new R&D. |
