In our last conversation, we came up with three increasingly strignent criterium for selecting a decent USB turntable:
  1. Ceramic cartridge never!
  2. Anti-skate
  3. Direct drive (remember, these are sub-$1,000 turntables)
I'm having particular trouble explaining the anti-skate requirement.

Here's what I'm hoping HA can answer:
  • Do turntables without anti-skate, such as the Audio-Technica LP2D-USB, truly have no compensation and ride the inner groove like a surfer catching a wave?
  • Someone at the Vinyl Engine suggested that the weight of the "high mass" tonearms found on such TT's essentially force the stylus into the middle of the groove. Thoughts on this?
I need some compelling reasons to choose a deck with anti-skate, especially for people who don't plan on replacing the cart.

There's already a good reason to choose a TT without anti-skate: Newbies don't need to learn how to balance their tonearm.

Thanks!

My anti-skate questions are answered, so let me get right to the direct vs. belt drive requirement...

Where does that requirement come from?


I realize the direct drive requirement is up for debate and I am characterizing it as such in my upcoming comparison guide.

Certainly I'm not the expert here- you guys are. That said, here's how we got to this requirement:
  1. We're talking about USB turntables in particular. The best built turntables in this class are DJ turntables, which are almost exclusively direct drive.
  2. With the exception of the Pro-ject Debut, the wow and flutter specs on direct drive turntables are the best. Of couse, this says nothing about motor noise on badly implemented direct drive system. And none of the w&f specs even approach the legendary SL-1200.
  3. Direct drive USB TTs are the most expensive (again excluding the Debut) and generally don't come with a cart. The higher cost (hopefully) gives more room for better motors.

There are two different approaches, and the question is: which one degrade most gracefully at the given price point? It depends, but generally, belt drive is preferred.


I think this is the nub of the debate- are the specific USB TT direct drive motors implemented better than belt drives? I can't answer that but I can give you names- Stanton, Numark and Kam make the DD USB TT's.

If you exclude the crap- USB TTs with ceramic carts and/or no anti-skate adjustment- you are left with few decks.

The belt drive turntables that remain (excepting Pro-ject) are either cheaper or have novelty features like recording directly to CD, iPod or Flash.

Based on the specs, the price and the fact that DJ's probably demand better fidelity than consumer vinyl archivists, we arrive at the debatable direct drive requirement.

But a poorly implemented DD system on any of these models could throw a monkeywrench in all of this.

The OP implies there are "good" USB turntables - but are there? It might be a simple solution, but surely the "good" solution is a decent turntable, reasonable pre-amp, and reasonable sound card.


I didn't say "good," I said "decent." Decent < good in my mind! smile.gif

I am devoting considerable space to an "Are you sure you want to go this route?" section featuring a large, eyecatching SL-1200 photo. My readers will know that there is a much better turntable in this price range and offer tips on getting a non-USB TT connected to their computers.

I'm loving the conversation and challenging my statements and assumptions. I appreciate your help in getting my story straight before I publish.
