Wow a lot of variables to consider, turntable/arm, phono stages and the such but once you make the switch you will notice more realism to the music there is more of if thicker, darker, moodier. I switched from an ADC XLM II and a Grace F9R in 1978 to a GAS Sleeping Beauty and have never looked back, for very long, still have a SS rebuilt Grace F9R on another arm wand that I enjoy from time to time. There are folks here on Audiogon that marvel at their MM and I am sure they can make a case.
