I got the Lyngdorf TDAI 3400 yesterday and put it in my system right away to power the DI SEs. I fed it first from the OPPO UDP-205 and played some CDs and then from Roon Nucleus+ to listen to some Tidal/Roon streamed music. Even though the Lyngdorf is brand new and was only shipped to me two days ago directly from Denmark (yes, over night), without any break in time, I can positively say that it is the best sound I ever heard from my speakers. I did not even get a chance to do any "room perfect" measurements or corrections yet. This was all straight in and out. Today I will get a chance to start playing with it and I can't wait.
