@lewm - you certainly are not a cheapskate with all those cartridges. I assume you have several turntables as well.
I like to think of myself as more "value conscious" than a cheapskate as 99% of people who are non-audiophiles would think I am crazy to have a low 5 figure total stereo investment and equal on the software (records) side.
I might have thought I was crazy if I was looking at me now when I was starting out the audio quest back when I was in college.
Everything is relative, and I guess if $70K is monopoly money to someone, that expenditure on a phono stage is reasonable with a total stereo (bad) investment of $400K or more, especially if it is a vinyl only source system like I have. For some reason, $400K for an entire system is not as shocking to me as $70K for a phono stage or $10K for a power cable.
