Hi PVP, KrellFan1 and Billy Buntner, A have a bit of time with these components here. I love the Tambaqui; I have one stand alone with the Grimm mu1, and one inside the Makua pre amp. I did have the Kalugas with the Makua. so pretty. But then I got Audionet Max amps downstairs and brought them up to try with the Makua / tambaqui. Sooo much nicer. bye Bye Kalugas. The Makua w Tambaqui into Max amps is so resolving, fast dynamic, yet relaxing and much more spacious and subtle. I am an Audionet fanboy with Tambaqui DAC and now Grimm Streamer and Core. Waiting for Grimm update to add a second mu1 as a Roon endpoint only.
