I had the opportunity to do some side by side listening, and the different units were very easy to tell apart. First up, my old style Klimax DSM with Organik upgrade. Driven by Luxman M10-x and Sonus Faber speakers (sorry, didn't catch the model).
Listened to that set-up long enough to get acclimated to the dealers system/room, then switched to the new version of the Klimax DSM. A rather surprising difference between them. From the upper mid-range and up the new unit was a marked improvement. More detail, less veil, less digital. The bass tightened some, but the primary changes were in the top end.
Switched to the T+A unit (SD 3100 HV into the T+A integrated, but still using the M10x for the amp). It completely matched the new Linn on the top end, but now there was a much fuller, more foundational level of bass. Not big and boomy, but just enough to really complement the high end. You could easily change the amp and build on the unit's bass.
While I've always enjoy the Linn sound, I also have found it a touch lean. The T+A resolves that completely. So I made the change to T+A. Highly recommended and worth a listen.
