Belts and rim drives are complicated if dd is. Well built dd tts are quite reliable. That's why they generally were favored by many "disc jockeys". Radio stations used disc jockeys, and at one point were a large user group before going digital. The Technics SP10 is legendary. Not Gerrard (whose reputation generally is quite overrated).
The point is that both the Garrard 301s and the Thorens TD 150 are iconic. Both were in the top TT of all times, the Garrard 301 number 1 on the list. The Garrard 301 is iconic as it was the world's first truly Hi-Fidelity turntable. This turntable was produced before the synchronous motor and electronic speed control. The speed control is managed by an ingenious eddy current brake as part of the motor assembly. It works superbly. Although an idler wheel design, its rumble specs are superb, and rumble is not audible. This was achieved by outstanding and legendary craftmanship. They have stood the test of time and are a monument to the precision engineering of the time.
The Thorens TD 150 is iconic in that it was the fist turntable with synchronous motor and belt drive. Its beauty is its simplicity. I have only changed the belt once in 67 years and that was only because I thought I should.
I know that turntables and LPs have a vogue, and excellent turntables, superbly engineered arms and cartridges, can sound very good. But everything has to be obsessionally set up. Even at their very best, with the finest recordings, they can not compete for fidelity and convenience with digital audio.
So I am honest about it, and refer to my turntables, reel to reel, cassette machines and associated equipment as the museum section of my system. That is exactly what it is, and restored and maintained to show just how good it really was and is. In this way history is properly preserved. Whether future generations will have this desire to preserve our audio past, only time will tell.
