I think it’s a good pick especially considering your in an apartment and probably can’t really crank it I’m assuming. The Lyngdorf 3400 will give you endless tweaking for lower volume listening. IME without the room correction engaged it sounds very good and clean. Not digital like a lot of class d. With the room correction and subs dialed in and subs engaged in my room it was totally transformed into something really special. Never heard a Hegel but have heard pretty good things.
I thought about getting the 3400 myself. According to my dealer the very reason they came out with the 3400 was to handle lower efficiency speakers better than the 2170.
