Where is the next generation of direct drive?

I hear a difference in favor of DD. There are many belt drives I've heard that I could easily enjoy but DD is not only more convenient, it also is more dynamic with more bass slam.
The problem with making modern "advances" in DD technology is the cost of doing that and the fact that you're dealing with a niche product. No large corporation is going to spend millions in R&D to sell a few hundred (or even thousand) turntables. The small manufacturers mostly just can't afford to. That's why the best vintage DDs are still the way to go for DD sound but have gone through the roof pricewise IMO. As long as my DDs are running I won't be going back to belts but I'm glad many prefer belt drive. It makes the old DDs a little more accessible.

I just scored a cheap ADC DD unit-- I'll tweak it and see what I can do, post results if anyone is interested.

Onkyo also made adequate DD decks, resembled their belt-drive units of the same era. At this price point, BD/DD performs about the same. Cheaper than dirt, so not much to loose in trying. My hunch is the small, lighter motors may have an advantage over the massive over-engineered ones. Its probably the nasty plastic plinths and auto-return mechanisms that mess things up the most.

You can't really compare the current direct drive high end models to the old Denons, etc. It's a whole different league and they have to be evaluated separately. I've only heard the Grand Prix Monoco extensively and I wouldn't say there's a belt drive turntable in it's price range that sounds better just because it's belt drive. I think at that level the difference is blurred.

I took on the TTWeights line of tables for this very reason. You can switch back between ultra quiet rim drive or tri belt drive. It offers something for everyone, no matter what your design preference. I only have the belt drive up right now, but in a week or two I'll be able to switch over to the rim drive, and I can post back my impressions. I think having 3 belts is paying dividends in terms of PRAT. Before hearing this table I thought high res digital offered the best sonics on a consistent basis. Now it's the table that makes more recordings sound realistic.

I wouldn't say belt drive designs are bad, I've owned and enjoyed several during my decades in this hobby.

But I do find good DD and rim drive designs to be more accurate and musically satisfying. The most obvious example came from a friend recently when he installed a Teres rim drive to replace the belt system on his VPI Scout. Some would consider this an unusual modification since the Teres cost as much as the Scout table and arm package. However, just a couple of minutes listening to a solo piano recording revealed the significantly improved accuracy and musicality which far better resembled a live piano. Other instruments and voices benefitted as well but the piano provided an easy and immediate comparison.

Specifically to the OP's question, I agree with everything that Sonofjim said about DDs as it was a better summary of points I was suggesting in my previous post.
