Hi Dave,
I made the move to the Lyngdorf TDAI-3400, and sold my DAC and integrated amp. I still have an Allnic H1201, so there are still some tubes in my system, and I must tell you that even though I was skeptical of how vinyl would sound through the Lyngdorf, I am very pleased with it. To my ears, it sounds very natural and musical.
I have no regrets at all and love the tremendous flexibility of the Lyngdorf as well. Digital is great, streaming is great, vinyl is great. In terms of sound and convenience, the value is just off the charts.
I also love the Tektons, which sound great with the Lyngdorf. Which model or models are you considering?
