agisthos: Yes, you have it correct. I was surprised at the difference between them. In retrospect, I think this makes sense. Those who purchased the new KDSM as a system hub (no included dac since this is for active speakers with dac included in the speakers) have also reported a significant improvement once installed. So there is more than just the organik dac going on here with the newer Linn.
mgrif104: I used the preamp, streamer and dac in both the previous Linn and with the current T+A. With the Linn I used their app until just a few weeks before I traded it in. I had moved to Roon in preparation for using it with the T+A, as the dealer said the T+A app was nowhere near as polished as the Linn app. That turned out to be true. It works, but it is rather crude and limited relative to the Linn app or Roon.
