It would be a mistake to believe these high-priced CDP/DAC's will "blow away" or outperform by "twice" other well-designed components at 1/2-1/5 their price.
The audible differences are often much more subtle than that, and while a good Wadia WILL blow away your average mass-market DVD player, it will merely sound a little better than the competent, less-priced competition such as Linn Ikemi, ARC CD2/3, Bechmark, etc.
I've listened to various Wadias over the years, including the venerable 861. They are all great pieces, but there are certainly less expensive pieces one should investigate first before plunking down the Loooong green..
