Thanks for the listening notes S Clark.
I love the LS9’s too. In my room however I couldn’t tame the bass nodes they excited. I never considered DSP as I had never heard one that was transparent enough to satisfy me.
When I read a review on the Lyngdorf TDAI 2170, I thought what the heck, I should give one a try. I’ll sell the thing if it sounds bad. I wanted a new DAC anyway and It wasn’t crazy money. The tech used in the design was light years ahead of what most companies are putting out.
All I can say is if I had owned this amp when I built my LS9’s I would still have them. Using well designed DSP and digital crossovers is a game changer for room issues. I could never go back.
I have had some crazy good speakers overt the years, yet getting a well balanced in room response with killer imaging was almost impossible. One or two dB peak or null in the wrong place just bugs me after a few weeks. So I would sell the speakers and try to find something better.
You should hear the Altec’s with just a touch of DSP magic. They can’t Image like the LS9’s, nothing can. But they make lifelike music indeed.
Bring us up date this spring when you get them outside. going to impress yout guests for sure..
