Ooh, will have to give this a whirl. The guy who sold them to me was very enthusiastic about how well they'd served him over the years so I'm excited to get them wired up once my wire arrives tomorrow.
Another thing to consider: head over to your local Goodwill and snag a cheap-ass CD player and a few CDs. I don't know your experience with audio but I used a similar set of speakers for years to stream music through Spotify, and the difference in audio quality between streaming and a CD blew me away. HQ audio files that you have locally will work just as well.
