You guys can curse me all you want. I wasn't the only one thinking the question was not well thought out.
If the OP is really trying to decide where to compromise between the amp and phono stage, I suggest flipping a coin. The pros and cons of changing a source component over an amp are easy enough to list. So make your choice and start saving for the next upgrade. You really won't hear the improvements until all of the "links" are fixed. Incremental changes, sure, but not all there is. That is really all there to it is unless you just want to participate in some mental masturbation. But audiophiles like to do this a lot. Hell, I am surprised we haven't gone down the "treat your room first" road. :-)
