How about this for a plan: Purchase a high quality separate phono stage, and connect it to a line-level input of your existing preamp. Compare it to the results you have been getting with the preamp's built-in phono stage. If there is not a significant improvement, sell the new phono stage. If there is a significant improvement, you can then decide whether to stay with the existing preamp and power amp, or replace them with an integrated amp.
Also, FWIW, based on everything I've read if I were shopping for a separate phono stage in the price range you seem to be describing, number 1 on my list of candidates would be the Herron VTPH-2.
