I bought a Lyngdorf 2170 for my downstairs system. My living room is not a good sounding room, and the Lyngdorf Room Perfect correction really made a huge difference in a problematic room. If you don't have a well treated dedicated room, Room Perfect can be a game changer. My Lyngdorf displaced a very highly regarded 300B amp. I thought so highly of it that I encouraged two of my adult children, who are budding audiophiles in their own right, to go the Lyngdorf 2170 route. They are both well pleased with Lyngdorf. If you are running a digital source, inputing the digital signal to the Lyngdorf is astonishingly good. This digital from beginning to end thing that Lyngdorf advocates is the real deal. I am somewhat less enthusiastic about running analog in. My daughter wanted vinyl, and we had to get her a phono preamp. The built in phono on the Lyngdorf was just not very good.
I bought my Lyngdorf used. That kind of money for a superb integrated amp with an outstanding Internal DAC is just crazy cheap. Highly recommended.
