A great article in this month's Stereophile on what to do if you're wondering how to spend $1000 on cables - The Fifth Mark. He suggests buying / learning the guitar, hiring a quartet to play in your parlor, etc. etc., all in the same vein in which you ask your question - how to take the focus off the minutae and put it back on the love of the music.
My own answer is to buy a bunch of software. I regularly buy a handful of CDs (multiple times per month), and regularly listen whenever I can - on the "dedicated" system, on my office system, in my car. Talk about music instead of gear, turn people on to the cool music you've found (and you'll definitely find it). I find if there's always new music that I haven't fully listened to yet, I get more focused on that and less on the playback means. -Kirk
