Thank you for your response. I almost bought AT440, (what does MLb stand for or mean)??). Actually, I went cheap and bought the AT-120L ( actually not a bad cartridge for $96.00.
The Denon DL 301 MC would have to at least a 3.5mV to 4mV output to accommodate tne phono stage of my Rogue Sphinx integrated. The Nagaoka cartridges I have heard a great deal Would the lower compliance of the MP150 made that difference in the sound??
