I just made the jump after years with solid state. I bought an ARC 3SE phono stage and immediately noticed the difference and the synergy with my turntable and the type of music I primarily play (1950s and 60s jazz.)
Based on this experience, I added an ARC preamp and power amp and am thrilled with the sound, even in these early days of tube burn-in. Of note, even my wife noticed the difference and she typically never hears the difference.
