Naim introduce a turntable - the Solstice Special Edition

The TD124 drives the idler with a belt between the motor and idler, and (hence?) it also sounds a lot like a belt drive btw.

The belt is very small in diameter and traverses two pulleys of roughly equal or similar diameter, in contrast to the belt on any true belt drive turntable.  So the issues might be different.  But I have no business discussing a TD124.  Never had one in my own home system.

I never stay angry at anyone for very long. The TD124 sounds very much like an idler imho. 
I don't claim for a second that my two vintage decks are much above an 8 on a scale of 1-10 as to the worst and best out there. In fact, I don't particularly like the clunky feel of engaging the drive lever on the Thorens and I grew up with the table as a teenager way back in the '70's. But overall I do love almost everything else about both decks. 
But I have gone off topic. This was about high mass platters. 

Having heard the 301, Lenco and 124 in the same systems, I felt the 124 sounds the most refined with a more belt drive-ish flow and momentum. But I agree it sounds more idler type when compared to a TD 125, (heard in the same system)

@lewm , I did own a TD124. It was my first real turntable (excluding my two Zenith bug eyed specials). You are probably right to like it least of all.
It was however, a boat anchor. You could probably drop it off a 10 story roof top and not hurt it. 
Every turntable in commercial use was used to slip que. The enemy of radio is "dead air." You had to know exactly when a song was going to start to the 1/2 second. What the DJ did was place the tonearm down on the record with the turntable off, "jockey" the record back and forth until he found the beginning of the song, hold the record in place with two fingers on the rim of the record and start up the turntable. At the exact moment he wanted the song to start he took his fingers off the rim. 
By design, the limited torque of a belt drive turntable made this maneuver impossible. You were supposed to slip the record on a felt mat but that created tons of static. Many DJs like me (campus radio station) just held the rim of the platter and let the idler do the slipping. Great way to tear up an idler drive. Direct Drive cured that problem but my DJ career would end long before it came around. The Idler drive was not designed specifically to slip que. It was simply the best way at the time to have multiple speeds on a turntable. Electronic motor drives were way off in the future. The AC synchronous motor running on line frequency was it.
All of the changers of the day used it. I'm not sure but I don't think there ever was a belt drive changer. Not enough torque to drive the changer mechanism. Direct drive put and end to idler wheel tables in commercial use. Audiophiles had drifted over to belt drive tables as the old idler wheel tables were noisy as all get out. The Thorens TD 125 was the turntable to have in the early belt drive era.
