I have an old TEAC 3340S I dont yuse it from ten years now, this weekend I plug a Senh 421 in and I compare with my Sebatron vmp-2000 and my Studioprojects VTB-1, the Sebatron have a more full and warm sound, the VTB-1 his thinny and a bit harsh, the 3340 have a nice sound, less bass then the Sebatron but he have a warm sound and that give me four extra pre free.
