Just another approach...
ask your friends to bring over THEIR music. I have found that when non-audiophiles hear the music they like on my system they find it to be a more enjoyable experience. When it is their music, what they get is how my system creates and presents that music, not how I can 'wow' them with the typcial audiophile sound attributes.
Once they hear a couple of their CDs or records, then I will ask them what else they like and hope I have a good recording of it. Most times I do. Only after listening to their music will I pull out some sonic spectacular like a Direct to Disk mastered LP.
