French_fries,
frankly speaking I doubt that (SA)CD player development has seen relevant progress in the last couple of years, so I'm not really surprised that the 390S still does a great job! The same might be true for speakers as well... After 20 years of music reproduction experience, I came to the conclusion that basically all the equipment out there is not too far away from what is possible and it's mainly a matter of personal taste if you decide for ML, Krell, BAT, Einstein, Jadis, Esoteric, Revel, Reimyo, Burmester, ....
Do you use a pre-amp with your 390S???
