Congrats @jsalerno277 !
I've had my Tambaqui for a bit now and it continues to amaze! I also have Vivid speakers, Giya G2s2s and love them. Plus, my electronics, Audionet, are similar to your Burmester in that they are clean, fast, resolving and non fatiguing! I am curious do you run Roon or Conductor (if you are streaming through an Aurender)? I am also pretty sure you heard the Grimm MU1 streamer with the Tambaqui if you were at Bill's. My best sound running Roon is through the MU1 into my Tambaqui. I have also upgraded the internal ethernet cable in the Grimm to KS Realization through GTT and that made a noticeable improvement. . enjoy the Tambaqui!!!
