Your recent amp adventures; are these Lyngdorf 2170? Am much intrigued with this option, especially since KDude has embraced the efficient design. Cannot reconcile, however, my discouraging experience with Class D amps last year.
@craigl59 the 2170 isn’t a class D topology. At least not what you’re thinking of as class D. Kenny and Bill encouraged me to audition it against some pretty good tube and SS separates. I didn’t expect what I heard from it and it remains in my audio rack and the others were returned. I encourage you to give it a trial if you’re in the amp trail stages. Both my DIs and now my Ulfs absolutely love it with Digital and, unexpectedly, Analog inputs. I was especially flabbergasted when the 2170 sounded better than an LTA system on Analog. Digital, I could get my head around. But not Analog. But there was no doubt in my mind. But if you love tube warmth/distortion as opposed to detailed, analog accuracy, it won't be your cup of tea. My favorite description of is is a wire with gain. Everything in front of it and the Ulfs is reflected in the final sound characteristics. Even playing with USB cables and hearing the difference was a blast.
