I have converted 95 CDs into 96kHz FLAC files. I also have a 24 b x 128kHz album on FLAC. Obviously, my computer also plays CD discs. Now, no matter what the file is, when WinAmp plays it, outputting the digital stream to a Cambridge DAC USB port, the LED on the DAC front says 44kHz. The only time I have seen anything other than 44, it was 48 when playing a concert DVD via optical. What's happening? Do I need a new driver for my USB 3.0 port, or need to make a config setting change in control panel or the WinAmp? The other strange observation is that when ripping to FLAC, the file size ends up being the same as the WAV on the CD. I don't get it. The Dianna Kroll FLAC album I have is over 1.6 gig, and that would require more than 2 CDs of space even though the album play time is not any longer than most. My PC is a Dell Inspiron 660 and it does not have a optical output, or I would have already tried that. I wanted some advice before I add a new sound card to a brand new PC. I am also going to be ripping LPs using a NAD PP3i phono preamp (on order now), which has a USB output that connects to the PC. It comes with FLAC compatible "Vinyl Studio" ripping software that does 24 b up to 192kHz, but the NAD USB output is limited to 96kHz. I trust that will be enough to digitize in audiophile quality HD; but, I know that hearing the difference depends on the stereo system. I have a good one: Marantz preamp, Quad and NAD power amps, and 6 Magnepan speakers. Correct me if I am wrong, but the leap from 16b x 44 to 24b x 96 is a "mile", and the further move to 24b x 128 is going to be another inch past that.
