Thorens today announced two new turntables: the TD1500 and the TD403. The 1500 takes its design cues from the iconic TD 150 introduced in 1965 that according to Thorens's press release featured for the first time in a mass produced turntable a spring suspended sub-chassis with a flat belt driven inner platter. However, the AR-XA introduced in 1961 had this design feature and sold 100s of 1000s so must be considered "mass produced". The TD403 is the "big brother" of the recently introduced TD 402.
