Marantz receiver questions


I have a Marantz PM7001 that I'm perfectly happy with, but the speaker wire connections have gotten so sensitive that the speakers often cut out and I have to tinker with the wires to get the sound back.  I tried cleaning--nothing doing.  Worth taking into the shop or time for a new receiver?

I am playing classical and jazz on cds--Marantz CD6006, Paradigm phantoms.  Will I, a non-audiophile, notice sound difference between the PM6007 and the PM8006--worth the nearly 1K Canadian difference?

The PM7001 has binding posts that accept standard banana plugs. Go online and search for Nakamichi banana plugs. They attach by inserting speaker wire into a sleeve and tightened with a pair of small screws. A set of 8 are likely ~$10.  

 

I find it interesting it's cutting out with bare wires screwed on. That's pretty much as clean a signal as you can get. That binding post might be shot. Have you tried the second pair (system 2) speaker posts?
