If you're happy, remain so...don't do anything different. Almost any time I've changed thinking it was for the better, I have almost always been disappointed. There is usually an issue to resolve. Stay happy.
Cambridge 540P
I am just getting around to sending in my 540 for repair, and I was just wondering how much better the sound will potentially be when I receive it back over my receiver that has a phono preamp. I'm actually pretty happy with the sound as is, and it's sort of a pain taking apart my stereo cabinet--Cheers
