I got the dac & amp last night. With a/c out of the picture the only noise that's left is what's on the cd. Or the refrigerator upstairs when it's running. Otherwise, and I know it might sound cliche, but music emerges from an almost unnerving dead silence. The purity and realism these two components deliver has got to be heard to be appreciated, I just can't explain it. And that's only after a few hours of listening, I can't wait to get some more time on the amp & dac and for my real speakers (at 100dB/W) to get here.
