Just bought a new to me loaded Lyngdorf 3400 and have previously owned a 2170. Depending on your room the value of the room correction would vastly outweigh other factors by far. I just set mine up 2 nights ago and room perfect off and on is night and day. Also blends the sub perfectly. It’s also not an amp that has a sweet spot. Sounds the same from whisper to loud. Impressed for sure.
