The Audiomirror Tubadour III SE. It is a NOS R2R DAC based on the famous AD1865n-k chip, supplemented by duelund caps and tube output. The Tubadour III is a non-oversampling converter based on the AD1865N-K chip from Analog Devices. we have a new Audio Mirror component. It is the Tubadour III, which is a digital to analog converter (DAC) that's unique in many ways.

@charlesbreese i guess should add. I’ve owned the III SE. was one of my favorite dacs. I was thinking of buying it again, but now that Vlad has a new IV with transformer output (instead of the Duelund caps) I’m curious to hear who has heard it or could compare 

i have the III SE, the best DAC I’ve heard or had in system.. pure magic but I’m interested in the IV. Vlad is a wizard.
