Feedback from Ralph:

 Al, your DSD 32 bit DAC is fantastic.  No, make that Superbly Fantastic.  Never heard any dac sound this good, and I've heard some so-called high end and expensive ones here in California.  I'm running it from a MacBook Pro with Amarra.

I thought I'd never say it, but this is as good as my analog and Lp gear.. different, but still just as good.  Better in some cases.  Now my little system sounds like my 'big system!'   I'm going to put this thing in the big system as soon as I fix a bios problem with my Windows box.. cheap Accer pc.. paper thin motherboards.. lol!
