I just purchased the 640c v2.0 and it is a significantly better player than the original version. The two categories that stand out the most are: 1) a reduction in 'digititis", and 2) much improved bass resolution. I use PNF Audio speaker cables & ICs, VH pc into my Portal Audio Panache, XLO pc into my cdp, Polk LSi15 speakers, & cones under both amp & cdp. I would love to A/B this v2.0 player with Rega's new Apollo...
