Well, I finally got my TT hooked up to my Onkyo. I found a used Parasound phono preamp and used it. I must say the Turntable sounds great, better than it has in years. The last time I actually had it hooked up it was with my old Sony receiver. I didn't listen to it much because it didn't sound that good.
I believe the phono section in my old Sony was a piece of crap (it was so bad I was considering selling the turntable). I never would of thought there would be much difference with phono sections (whether seperate or built in to receiver).
