I appreciate the feedback and recommendations from everyone. My follow up questions are then:
What TT & cartridge and phono preamp's would you recommend to add to the VSi55 amplifier and KEF LS50's? Does a Gyro SE or Technics 1200G paired with a Sutherland 20/20 (I'm just throwing out items I've drooled over while reading about them but am unlikely to ever own) still make sense with that speaker / amp combo?
Or is a Rega P3 or P6, or maybe a Clearaudio Concept better suited for my Kef / Audio Research system?
I just don't want to get into chasing after gear, and I really like my speaker / amp as it is (and have had for about 4 years now) and am considering upgrading the TT & phono preamp to their level.
Thanks in advance!
