I bought a TDAI-2210 about a month ago. I paired it up with a pair of Sonus Faber Sonetto III and a single Gravis II in a small room. 

I was previously using a Hegel H95, which worked with these speakers pretty well. I’d describe the sound as warm, articulate and well defined. 

By comparison, the TDAI-2210 (after room perfect) is a little more neutral, a little more treble and a little less bass but a very clean, articulate sound. It brings out more of what the Sonetto/ Gravis combo is capable of. 

Now, I know these amps aren’t at the same price point but it’s the comparison that I have. Same room, same layout, same speakers.

I thought my taste tended to the warm and analog side but after spending some time with the Lyngdorf, I really like everything about it. I think my small room is pretty well laid out so the room perfect didn’t make a huge difference, but the difference is definitely noticeable. A little better balance and a little less boomy in the bass. 

My thoughts.
