Tube DAC without output transformer?


Which ones exist, regardless of price?  I know of the Aqua DACs, which use a tube-mosfet type output stage.  This fits the bill because it lacks a traditional output transformer.  I believe most other DACs that have tubes use output transformers.  In essence, I am looking for an OTL DAC.

Owned an Audio Note Kits 2.1b with AN Silver coupling caps. Excellent sound very real and holographic.
roberjerman, yes, you are right.  So I guess most tube DACs are configured this way.  Thanks for clarifying.
A tube cathode follower does not require an output tranny and has sufficiently low impedance to drive a cable.
I think tubed Dacs with capacitor coupled outputs are the norm actually. In terms of transformer coupled output Dacs Audio Note and SW1X come to mind.
Excuse my ignorance but what benefits would this give? I’m assuming more transparency?
