The 640P features a highly specified moving magnet stage, as well as the higher gain needed for compatibility with high-end Moving Coil (MC) cartridges.
This model features single ended "class A" gain stages and use discrete transistors instead of the more common integrated circuits. This gives less crosstalk and interference across the signal path, with both designs delivering high gain and linearity. Tthe 640P uses passive audiophile RIAA eq, the optimum type for phono stages thanks to its complete lack of phase error.
The 640P also uses superior amplification circuitry for its MM and MC stages to provide the lowest possible distortion and noise. In addition, this flagship model employs multi-parallel capacitors to achieve exceptional RIAA accuracy of +/- .3dB up to 50 kHz. It also features a defeatable subsonic filter. This combination of technologies offer a hugely dynamic, involving and open sound. | | | Features: | |

Great sound!Jul 18, 2009
This sounds great with my older Dual turntable. Very clean sound, great instrument separation. The single blue LED on the front is small and not overly bright or distracting. Plus it supports MC cartridges if/when I should ever upgrade to one of those.
BTW, the MM and MC inputs use completely different circuitry (from my research), if that's important to you.
