Just remember that the phono stage is the most important part of the amplification process as it provides the most gain. This is especially true if you use a low output moving coil cartridge.
My advise would be to buy the best used stand alone phono preamp you can afford and run that into your current preamp aux input. If you feel the need later you can upgrade that part without changing the whole preamp.
