Curved and Straight Tonearms


Over the last 40 years I have owned 3 turntables. An entry level Dual from the '70's, a Denon DP-52F (which I still use in my office system) and a Rega P3-24 which I currently use in my main system. All of these turntables have had straight tonearms. I am planning on upgrading my Rega in the near future. Having started my research, I have noticed that some well reviewed turntables have curved 'arms. My question: What are the advantages/disadvantages of each, sonic or otherwise? Thanks for any input.

Why is it that most of today’s cost no object SOTA arms employ a straight arm tube. Where are the super "S" arms?

Good question. While at it you could ask why are cheap plastic (acrylic) light weight turntables promoted over heavy plinth steel/wood traditional designs?

I think production and shipping cost has something to do with it...not sure if all the marketing hype about better sound is as real and tangible as all the production and shipping cost savings.

Like Harbeth light weight waffling speaker cabinets - I don’t buy into the hype but I do understand how a cheaper build and lowrr packaging and shipping cost is a big competitive advantage...

You have no idea what you are talking about. Harbeth and many other British monitors use the BBC thin wall design for a reason,and it’s not for a cheaper build ! Check it out!

At your price point, you can consider going a refurbished Sota and start looking for a good condition Graham 2.2 arm or similar.  The Graham features VTA adjustment on-the-fly.  That is one of the biggest improvements in playback quality you can make.  You could also consider doing the same thing with a mid-priced Rega or other non-suspended table.  They may not be suitable for your installation, because it depends on how well isolated the table location might be.  Either way, you have a lot of excellent choices to consider.

Take your time, do as many auditions as you can, watch the postings here and most importantly, have fun!  Good luck & happy listening!
