Difficult to answer as there are a lot of system variables - e.g. speaker or headphone-based system, cables (interconnects, headphone and power), easy or difficult to drive headphones, dedicated headphone amp, power supplies to mention just a few, and then there is personal preference with different aspects of sound quality (there’s more to that than just transparency). As a headphone user I have DAVE, M Scaler and TT2, and when trying comparisons earlier this year, while I mostly preferred DAVE/M Scaler over TT2/M Scaler, there were times when I preferred the latter combo for the greater feeling of power and control over my Utopia and HE1000se headphones. But my system has changed since than and I’m not sure if I would feel the same way today. I’ve not directly compared TT2/M Scaler with solo DAVE.
