Jean-Christophe,
I had the LP12 from 1984 to 1989 and then again for 3 months last year. While I like how it is singing, in my opinion it is essentially flawed: it sounds veiled, definitely.
My main turntable since 4 years is the famous German Scheu turntable (see http://www.scheu-analog.de), with special 100mm high platter weighting 10kg, with changing tonearms every week. My secondary turntable for wife and living room is a mint condition Thorens TD124-1 with SME 3012-2 and Denon 103.
In the meantime, I tried a Voyd the Valdi (in every respect better than an LP12, but less singing).
regards,
Hartmut from Munich
