Funny, me too (10-year-old Technics rack system). I'm still getting used to the new sound--it's quite different from what I got out of the Technics system. But, an incredible improvement. I couldn't believe the difference. Going from the Technics components to the Harman Kardon 230 made a lot of difference. Then, before I wired in the Axioms (I hooked up the M22s first), I listened to several passages on the Technics speakers. I then hooked up the Axioms and couldn't believe how much clearer they were.
I'd like to listen to my entire CD collection at moderate volume to discover what I've been missing. Trouble is, we have 16-month-old twin boys. You can imagine what it's like trying to listen to music when they are awake. And, I can't turn it up when they are asleep--or they won't be asleep for long. :-)
