Wadia 631 grainy and "dirty" sounding vs ML 390s


I have heard the ML 390S. Excellent player. However, I have been told in comparison that the ML 390S is cleaner sounding compared to the Wadia 631 which sounds "dirty" in comparison. Does anyone else have a similar response?

Are there any other players in the 7K-8K range that exceeds these two in performance, build etc?

I personally found the ML 390S to be the more musical unit than the two Wadias I had heard and bought the ML (which I subsequently sold for an Accuphase which in turn I then sold for a 47 labs transport and Audio Note Dac). I would not characterize the Wadia as "dirty" though by any stretch of the imagination...

The Audio Aero Capitole CDP and used Burmester CD001 (at ~7k) are also exceptional players with very different sounds. Which is best will depend on your preferences and your system... which of course brings the question: what gear is in your system?
