Don't have a Tera Player but my P1 screenless DAP does sound great; still the best sounding portable in my collection. Removing the screen and wireless radios reduces noise, jitter, etc. Think of it like a race car compared to road going version of the same car. The race car is stripped down, inconvenient, and much less practical but also performs much better. If all out sound quality is the target, displays are less important and who cares what format the audio is in. Come to think of it: has anyone ever seen a turntable with a screen....?
