I am sure the OP is not interested in a $1K+ modded arm. Going back to comparing the Pro-ject and Rega arms, I have used both types. The Rega is longer and should have lower tracking error. The Pro-ject antiskate setup is not that great but then you have no VTA adjustment on the Rega unless you buy shims or custom VTA adjusters for extra $. Both are a pain when it comes to aligning/swapping carts due to fixed headshells. If you are considering turntables rather than arms alone, the Pro-jects are a better value for the money. The Rega TTs are a bit pricey for what they are more so if you need to add a speed control box. Avoid Edwards TT stuff.
Which is the Better Tonearm - Pro-Ject or Rega?
Which is the better arm in your opinion, the Rega 251/202 arm that's also found on the Rega clones (Edwards Audio TT1 for example), or the Pro-Ject arm found on the Debut/Essential and Pro-Ject clones (such as the Music Hall MMF 2.2).
Does Pro-Ject's carbon arm (as found on the Debut Carbon) change your position on the comparison?
Thanks!

The Rega arms are cast alloy - compared to other arms they are very stiff and by comparison to other materials they are more acoustically inert - that's what makes them better than other arms. Arms that use alloy or composite tubes, are not as stiff and can be acoustically active (they vibrate) Jeff at Audiomods has taken the Rega arm tube further and found a way to make them even stiffer with internal bracing and improved the acoustic damping by drilling holes. The Audiomods arms only use the Rega arm tube - everything else is all Jeff's design and fabrication. For the price, they are a great upgrade to a stock Rega arm and mkae a significant difference.

Ok, as an engineer, I feel obliged to chime in. Castings are cheaper than bar or tubing. Tubing and bar, forged or rolled, have more uniform density than castings. Even if the most advanced casting technics are used, you will still have some internal casting issues, it's the nature of the beast. So maybe Rega uses cast pieces for economic reasons. Let's not fall for the marketing fluff about castings being more rigid and acoustically inert and all that stuff. I am willing to bet this claim has never been substantiated. |
Rotarius - here's a link that explains some of the advantages of casting. Granted, it talks to steel, but wouldn't the same be true of any metal? http://www.afsinc.org/content.cfm?ItemNumber=6931 One valid point about casting... "It puts the metal where it is needed" Here's another link that measures attributes of the Rega 301 arm against other arms... http://www.hi-fiworld.co.uk/index.php/vinyl-lp/70-tests/104-arm-tests.html Also a quote from Wikipedia... "which has a now tapered cast alloy tube[22] that offered greater rigidity and better control of resonance" As for your statement... "So maybe Rega uses cast pieces for economic reasons" It took them over two years of R & D to get it right - "economic reasons" - I doubt it. What you say may have some merit, but I think Rega's reputation and track record carries more weight than your conjecture. Regards... |
