I use the Lyngdorf TDAI-2170 as a preamp with RoomPerfect. Using the 2170 menu I disabled the amp and I feed a Parasound A21 from the 2170 analog output. The Parasound drives Maggies and a SWARM sub system. Clean, detailed, easy and puts a smile on my face. I will say the 2170 menu takes time to understand but I learned the navigation and can use the extreme power of RoomPerfect to give me great sound.
Dumping it all for Lyngdorf???
I'm seriously thinking about dumping ALL my HiFi gear and settling on a Lyngdorf TDAI-1120 and a pair of KEF LS50 Metas and be done with it......Current system is Node2i/Gustard X16 DAC/ Schiit Freya Preamp/ VTA Dynaco ST120 Tube or First Watt F5v2 Class A or ICE Power 200 Class D or Yamaha M45 Class A/AB.......With LS50 Metas.
I'm really intrigued with the whole Lyngdorf thing of room correction, full digital nearly end to end, all in one, fantastic GUI, and about 1/2 of what I have invested $$
Might see if a dealer will let me try one.....
