This is an off the wall suggestion. I'm not a fan of many tube electronics but I auditioned an Asthetix Janus last week and I was left almost rethinking preamplifiers. My favorite feature was the ability to invert phase via a remote control. One of the most frustrating audio issues I find is an almost complete lack of concern by recording many engineers to have phase continuity. Another very nice feature is cartridge loading via remote. Again, another trick that can improve some LP playback.
Ayre KX-R or Krell 202 with Martin Logans
Looking at adding 1 of these 2 preamps with my ML's. If anyone has any other suggestions please let me know. thanks
