Anthem STR or Lyngdorf TDAI 2170?

Guys, It is not one or the other. It is both. You always have to optimize your room acoustics. Once you have done that Speaker Control (Not Room Control) adds an additional dimension that an uncontrolled system simply can not match. Every single serious audiophile who has heard my system adds speaker control and are thrilled with the results. First, you can modify the frequency response to suit your taste and conditions. Second, the response of the speakers is now exactly equal improving imaging and depth. Third, all speakers and subs are now perfectly in phase. The system delays the closest or fastest speakers to match the farthest and slowest. Screwing around with room acoustics will not do any of this. You can not have the best performing system without it. If you are ever in New England I would be happy to demonstrate.
I guarantee a jaw dropping experience.

I have a Lyngdorf 2170. I have not heard the Anthem STR but a dealer I talked to that sells both Lyngdorf and Anthem said the Lyngdorf is way better. I am really happy with my Lyngdorf. The room correction works great. I do have an Anthem MRX 710 and can confirm that the Lyngdorf room correction is better than the Anthem in my room. 

I generally do not add comments but I must say it is very annoying when people with their own agenda or products to sell hijack a post. The original question as very simple. Lyngdorf or Anthem? Why mention Naim or another products. Obviously Dave and Troy Audio Doctor do not sell Anthem or Naim. LOL 

I would suggest changing speakers.  Those are impacting your dead sound in the smaller room 

Room acoustics first. They will make everything sound better and the room more speaker friendly. 

THEN do the room correction. This is my advice and that of professional acousticians. Room acoustic treatment make DSP equalization work much much better.

Appreciate everyone’s input on this. And I 100% agree with @cjw... it’s always nice to get suggestions that aren’t being driven by a sales agenda and are as close to impartial as possible. Know this hobby of ours is very subjective, and that’s what’s so great about it, but it doesn’t need a sales agenda informing that subjectivity.

After a lot of conversations and research I ended up going out on a limb and getting the Micromega M150 at a really good deal. Realllly curious to see how this performs and will follow up on this thread when some thoughts once I get it into rotation.

Thanks again everyone!
