Is Direct Drive Really Better?


I've been reading and hearing more and more about the superiority of direct drive because it drives the platter rather than dragging it along by belt. It actually makes some sense if you think about cars. Belt drives rely on momentum from a heavy platter to cruise through tight spots. Direct drive actually powers the platter. Opinions?

Raul,
I'm in general agreement that measured numbers determine the accuracy, but I will take issue on one small nit-picky area.

Lumping of wow and flutter is misleading, because I suspect that the frequency distribution of the wow and flutter noise will have a very pronounced effect on the perception of sound quality, just as it does with digital jitter.

I could have a table that had lousy wow measurement at 0.5Hz, but I suspect it would be much more pleasant to listen to than a better measured table with wow around 2kHz, right in the midband.

I truly believe in measurements and a scientific approach to audio, but often the most difficult thing is knowing exactly what to measure.

This has been a really fascinating debate, by the way, and I hope one day I'll have the time and/or the money to try a few more of the tables out there.
Just a thought. How many YEARS passed before it was recognized that one side of Miles' "Kind of Blue" was recorded and released off-speed? When the second side, recorded at the right speed, was available for comparison all the time? So much for our sensitivity to speed accuracy.
Albert,
I think that's a tremendous observation. A lot of people bickering about a subset and we've perhaps forgotten that we are all talking because of our agreement on a larger point which is the benefits of analog. Thanks for bringing that to my attention.
Upon mature reflection, I have to say that my last post is about as relevant as Raul's numbers :-)
Dopogue: That thought had occurred to me as well, and I think it's a perfectly legit observation. But I'm probably more immature than you ;^)

Macrojack: If I say I didn't think we were "bickering", will it sound like bickering?
