Just got the Xduoo TA-26 added to my rig.

Right now, I'm just running out of the Presonus into the Xduoo to get a feel for it, but ultimately I plan on using the TA-26 as a tube preamp, then using the Magni 3 as the headphone amp at the end of the chain.

Right out of the box, the Xduoo doesn't sound bad at all. The tube saturation is evident, without being distracting, like I remember on my old Little Dot Mk1.

I'll eventually roll the tubes, would love to hear your experiences with different ones.

Edit: Forgot to mention, I'm using Focal Elegias, 6xx, 4xx, K371, Grado sr225, and of course Portapros and KSC75s.
