the 6100 is a quiet running and elegant table. I would not consider a 6100 any "compromise".
The direct drives cost more to manufacture, and with at least other Japanese builders, there's no cogging of the motor and if engineered well no problems with noise. Some of the quietest tables I've used are direct drives- and even made the "quietest" tested in Stereophile back in the day.
Concern has been voiced over direct drive "cogging" but it's an exaggerated cla for the most part, though I imagine some lesser or early models may (or may not) suffer from this.
Belt can introduce wow and flutter themselves, but let's face it- once again an over-hyped claim, and most likely an issue with cheaper kit.
Any of these tables- a 6100, 6200, or 6300 will be great performers and offer no-compromise performance.
Me? Partial to quality direct drives. But as testament from a good friend who owns a 6100, it's whisper-quiet and a fantastic performer.
