Just when I thought the mist was clearing....
I have been struggling with this puzzle for quite some time now - to try and get closer to PC perfection, I continue to use EAC to rip uncompressed WAV files.
At the suggestion of another Audiogon thread, I probably overpaid for a Hagerman Technology USB interface box, which has a SPDIF out connection.
To not blow the budget completely, I picked up a used DAC to use with my desktop system - an Audio Research DAC 5 which outputs analogue to the preamp.
So far, it all sounds surprisingly good.
The midrange and top end are smoother than expected, but the sound lacks a bit of weight (bass?) and the image is a bit flat and lacking in depth, compared to real disks and my Sony SCD-1.
So Kana813 thank to you at last for the clear simple explanation to upgrade to Vista.
But now I need to worry about my USB powered interface and/or change to a firewire setup?
