Bel Canto DAC 3, USB from a Mac, is exquisite --
compared to my $2500 CD player ( brand withheld
in respect ). Apple Lossless, or uncompressed AIFF,
either, USB to a DAC like the Bel Canto 3 ... Best of
everything: no more shiny discs, iTunes interface --
which is not perfect yet, but, sure beats flipping discs.
Throw a couple of Bel Canto monoblocs
in the mix, and I haven't heard better except for maybe
the $30k + Linn activ set-up at my dealer. Maybe that set-up
was better ... but I'm not at all sure that it was.
