If you are shopping in the SA10 price range, I think you should get in touch with your local dealer and see what they suggest. They may be able to assist you in changing a component to bring the system more in line with what you want to hear and it's not always what you think. I recall being floored at the difference a preamp upgrade made during a dealer demo. I was absolutely certain I needed to change the amplifier, but the dealer showed me that it was the preamp causing the sonic issues I was hearing. He could have sold me either, so it made no difference to him.
Anyway, that's what I would do.
