Which receiver for better sound with vinyl?


I have an old stereo system from the '70's: Nikko NR-515 stereo tuner/amp, Marantz TT 1060 turntable. I also just put together a new home theatre setup: big Samsung plasma TV, Denon 1910 avr receiver, and Jamo 606 5.1 speaker system with Jamo 250 sub. I'm trying to figure out if I'll get better sound for music (vinyl) with a phono preamp and hooking up my tt to my new denon receiver, or keeping the two systems separate. If I keep them separate and continue using my old stereo receiver with the tt, could I hook it up to my new Jamo speakers, since they have two sets of speaker clips on each speaker to permit bi-amping? Would my Jamo speakers likely sound good with vinyl? Obviously, I would only use one input at a time!

the Nikko stuff from the late 70's had a pretty good phono stage, so its probably the cartridge that needs work. Hook it up to the Denon aux input and it should be fine. Dont run it into the Denon's phono input.
Have you ever cleaned your stylus or checked it under magnification? Unless you had a regular routine of effectively cleaning it, the stylus is probably caked with gunk and fuzz. When I got back into vinyl 4 yrs ago, my new cartridge went from sounding good to muffled in just a month or two. Viewing the stylus under a magnifier, all I saw was a big, black amorphous, fuzz-laced blob. Several applications of a dry Mr. Clean Magic Eraser (stroked from back to front, brushing off the abrasive flakes each time) finally cleared off the gunk and enabled me to see the bare stylus again. The sound of course improved markedly.
Got the new cartridge, and it sounds great! Of course, my brand new six week old Denon receiver is now dead (at least it's under warranty) so I just hooked up the Nikko directly to my Jamo speakers. It sounds fabulous. When I get the Denon back I'll listen to it to see if I like the sound as well. If not, I think I'll get an A/B switch so that I can share the speakers between the Denon for TV/BD where I need digital and the Nikko for vinyl.
