Replacing Sonic Frontiers Line 3 SE


Have owned it since new for a couple years, been extremely happy with it. But it's time to try something different, notice I said different instead of better.

Line 3 SE has great transparency, soundstage width/depth, and extension. Looking for something of similar calibre but maybe even more dynamic w/o losing the musicality. Does something like that exist? Also need both XLR & RCA in/out for flexibility and convenience.

Budget is $5k used or under, rest of my system can be viewed under virtual system.

How about early 60s NOS, Telefunken E188CC 7308, Telefunken E88CC 6922, Amperex PQ white label 6922, or Amperex PQ white label 7308 tubes.

What was the siemens tubes you used?
