Dazzdax, you seem to be forgetting that you are buying a dinosaur from the 50's that has the specific " SPU sound" that was used in radio station to get more presence coming thru.
that is a forward bump in the 200 to 1500 hz frequency.
This makes it wonderful for vocals, small ensembles, piano, even early beatles stuff
It is not a everyday cartridge if you listen to rock, pop or muisc with large dynamics.
God my SPU sounds crap with electronic or alternative rock music, but heavenly with Jazz like Ella Fitzgerald
