Regarding your comment I would say that you were listening to entire systems/rooms with numerous and different components. This wasn’t an isolated direct comparison between two CD transports . For example these systems probably had different speakers and likely dissimilar cable looms. These are just 2 significant variables amongst others.
I’ve heard the PWT with the Yamamoto, Metrum Octave, Vega Auralic, Aesthestix, Bricasti SE and Holo Springs DACs. In each case one easily can distinguish their individual sonic characters.
