The amp was new and I was able to put about 220 hours on it at high power levels before really deciding. Cables were stock, Nordost Frey2 and Wireworld Electra. I used the internal Dac with USB.
I gave it a fair trial and it just never sounded real to my ears. It had a vail that I couldn’t shake. Didn’t better the Ayre VAC or Luxman amps I’ve owned. The room perfect is great but my Devores are fairly easy to place. I did position them way out of whack,and when I did that, I was surprised how well the room perfect feature tuned them. I’ve heard other high quality class d amps from T+A and SPEC from Japan and while I appreciated some qualities, I just found that over time I was listening less. If I had the choose between the Lyngdorf and the SPEC I would go with the SPEC because it had more of that “in the room with the musician” quality that is important to me.
