Trying to get back into Lps, I seem to be throwing

I would appreciate some advice on what I can do to improve my record listening pleasure. I have rescently purchased the Project perspective turntable and have installed the Sumiko blackbird MC cartridge as well. So far I am very disappointed in the sound quality from top to bottom. At this point I seem to be throwing money right down the tubes. My equiptment consists of a McIntosh C37 preamp with the standard MM output and 2 McIntosh 7200 amps with Aerial 9 speakers. I also have an ESound E5 cd player which has been upgraded by Joseph Chow (early 70s Kenwwood fame).
