cause, solution, ideas please...

OK I am born again into the world of vinyl, my humble set-up is as follows:
Onkyo 1027F table
Audio Technica AT-92ED Cartridge
PS Audio 4.5 Pre-amp (with upgraded Cardas Silver Rodium output jacks)
on Navcom Suspension pucks, my table is 5 feet away from my Innersound Eros speaker on a heavy well built stand. I will say that I am not using any special interconnects.
Although I will never expect this to sound like a Walker, or even a Rega table...., but I get the sound of what can best be described as AM radio "like" high frequeny clarity especially in the cymballs and "S's"
Even at my table rigs price and age I dont think that this should be expected performance, if it is then screw vinyl, but please help me figure out what are my options, what may be the cause, and cheap solutions, at what amounts to a roughly $900 set-up (new) I cant imagine this is what should be tolerated.
P.S. my records are well kept and treated with Realistic anti-static cleaner with a velvet brush.
