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?

Btw, last line in original post is wrong.  It's a PM7001 that I'm thinking of replacing with a PM8006.

Pardon my ignorance, but do standard banana plugs fit with all equipment?  25 year old Paradigm speakers, 20 year old Marantz receiver--they'll plug right in to this equipment?

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.
