The Ultimate DAC for Approx $10,000

Hi There,

Over here in Australia, it's almost impossible to go and evaluate high quality DACS.

Therefore, I'm seeking advice from fellow Audiogoners for help with a new potential purchase.

Currently, here is my short list:

Audio Aero La Fontaine DAC
Meitner MA-1
dCS Debussy
Playback Designs MPD-3
AMR DP-777

I currently have an old 10 year old Audio Aero Capitole MKII which has served me well, but is showing it's age in terms of absolute detail, Bass tightness. Midrange is still excellent, coupled to a Supratek Cabernet Dual Pre-Amp, set of 300B SET amplifiers and WHT PR4 loudspeakers.

Feedback much appreciated.
