Suggestions from all you wise ones

This may be long but I will try to be brief. 63 years old, spent $1200.00 back in 1974 for my system. I'm known around my circle as a music nut. I only have a couple of friends that are into music as I. But, they have no systems, they would be happy listening to some old Zeppelin through a sea shell. I've been following this site for months and feel really upset that I'm missing out on my number one passion, music. I'm running a new NAD C165BEE That replaced my old Adcom GTP-500 II that started having balance problems, a Adcom GFA-555 II amp which I need to feed my Infinity Kappa 8's that are in great shape. Just got back into vinyl so I had my 1974 Thorens TD 160 tuned up. I think it sounds great. Is there any of you that live in the Milwaukee area and be willing to give me a listen to your system? Or any comments from you all.
Thanks Very Much !!!
Some more info, I have a new Grado Red cartridge and had to get a phono amp to run through a different input on the new NAD due to the lack of volume.
