Whomever designed that made some peculiar choices.
Reminds me a bit of Salk’s last design, the BePur3.

"The idea has been to combine the best in class loudspeaker drivers (Purifi), class-D amplifiers (Purifi), Digital-to-Analog converter (Okto Research), room acoustic treatment (GIK Acoustics), measurement technology (Klippel), software engineering (AudioVero), professional woodworks (ROSE Handwerk) and experience in speaker building (Joachim Gerhard)."

Rudimentary measurements show some diffraction and a recessed presence region, but other than that look surprisingly good: https://www.hifitest.de/test/lautsprecher-stereo/bauer-audio-om2-22668

My German relatives make very decent speakers.

My German relatives make very decent speakers.

Definitely, I have visited their R&D centre a couple of times.

A round section belt is poor engineering practice since stick-slip at the grooved pulley is inevitable.
It is measureably worse, but frequently used because it is much cheaper and easier to make (and may well be "good enough").
No surprise in a cheap TT always a disappointment in a pricy one.

I’m still confused about what a “ round section belt” would be as distinguished from any other type of belt. All of them would have to go around something so that’s what’s leaving me confused.

Unless you mean that you feel that all belt drives are compromised and you believe in direct drive instead?

Here’s mine FWIW:

I don't know much about turntables, but I'm pretty mechanically inclined (currently learning mechanical drafting at community college, and planning to get an advanced manufacturing certificate). I assumed that @Frank Dernie meant a round cross section (as in a piece cut from the belt would be cylindrical), and the mention of "stick-slip" confirmed it. I think he favors a toothed belt, which wouldn't be capable of slipping but is more expensive to implement (you need toothed pulleys to go with the belt). Honestly I've only seen toothed belts in higher force applications (car engines and bike drivetrains specifically), so I'm not sure if that's really necessary for a turntable unless the platter is extremely heavy. The Triangle turntable that was posted might qualify though, that looked like a huge piece of rotating brass.

Maybe round cross section belts as opposed to flat type belts. Used by Rega for example

I think he favors a toothed belt

In high-end turntables, the type of drive belt used plays a significant role in overall performance and sound quality. Among the most common belt types—round belts, flat belts, and toothed (or timing) belts—flat belts are generally considered the best and most widely used solution in high-end designs.

Flat belts offer an ideal balance between efficient torque transmission and mechanical isolation. Their broad surface ensures smooth and stable contact with the motor and platter, minimizing wow and flutter. This leads to excellent speed stability and low noise, which are crucial for audiophile-grade playback. As a result, many respected high-end brands (not even at ASR, but usually) such as Clearaudio, Linn, and Rega (in some models) use flat belts in their belt-drive systems.

Round belts, by contrast, are more commonly found in mid-range or vintage turntables. They are simpler and less expensive but tend to have issues with uniform tension and speed consistency, which makes them less suitable for top-tier performance.

Toothed belts, or timing belts, ensure very precise power transmission without any slippage. However, the mechanical interaction of the teeth can introduce microvibrations, making them less desirable for high-end audio where vibration isolation is critical. For this reason, they are rarely used in high-end turntables, though some specialized systems may incorporate them in hybrid configurations.

In summary, flat belts are (or were?) the most common and preferred choice in high-end turntable engineering due to their superior balance of smooth operation, low noise, and precise speed control.

I haven't had a record player myself for a long time, but I don't think that should have changed.
