sounds great!I got surprisingly good results, on test record rear channels identification was clear and distinct from front. So far, I am finding less problems than expected on CD-4, I got Grace F-9 and several Grado vintage ellipticals (Special Grado stylus) that work, even V15 III works in my setup, not best separation but no distortion also. Blue sounded OK on CD-4, my issue with this Ortofon is more the basic Blue sound is not my taste, not the inability to play CD-4 well.
good luck with it all, it sounds like its going really well
