I agree with xaudiomanx. I'll take a good cap over a transformer any day--provided the tube has sufficiently low output impedance to drive the load.

Does that mean that my Dac 2.1 with output cap will sound better than the Dac 3.1 with output transformers?

Good question! There are basically two methods for DAC/ pre-amp output stages and that is a Capacitor coupled stage or a Transformer Coupled output stage as you have gathered - one is capacitive and the other is inductive- both have advantages and disadvantages- hard to say one is absolutely better than the other - its like single ended amps and push pull or 300B vs 2A3 or EL34 vs EL84 - all are good -different approaches - red wine vs white wine - depending on the rest of the system - the capacitors and transformers used - the type of tubes and whether they are nos or new! etc.etc.. Some customers prefer transformer coupling and some prefer the capacitive output stage - AudioNote is heavily influenced by transformer coupling in all things - IV stages between digital and analog , interstages between power tube stages and output transformers in pre-amps and DAC's - thus they have invested alot in R&D in this area and have a huge range c core transformers with various cores and silver copper wire combinations! so its really a matter of listening your self to as much as you can and drawing your own conclusions!
