I agree with Angela's advice (7-22-01) Get your wife interested in listening. That is what I did. And not listening in the sense of "gee honey don't the new cables sound better" (ie, don't be an equipment geek). Listen to music , damit, not equipment. Put music on that she likes and for krisake, listen to an entire recording without jumping up to adjust something.
Also a some wine and snacks help. I have a dedicated listening room that has a lock on the door. We go to the room with the bottle of wine and some .... ur...um... oh, better leave that part out. But anyway,we put on some music, turn the lights low and lock the door (don't want kids getting out of bed and walking in unannounced, do we )and, shall we say, let the music carry us away. Which is what music is supposed to do. Oh, vaccuum tubes do indeed have a romantic glow.
This is what the listening experience should be. It should be about enjoying the music and incorporating it into you life. Not sitting with a bunch of fat, old audiophiles that all need hair combings, wondering if the new swithcplates make the mids to strident. Enjoy music, enjoy life, have fun.
