My philosophy is if there is not at least a tiny bit of sound improvement ( whatever you consider an improvement) when you first use, breaking in is not going to make things better for you.
@aberyclark
I agree. However, as I've reported, I now do and have been hearing a distinct difference. I don't believe it was on account of break in. Instead, I wasn't using the optimal type of music to discern a difference and I wasn't necessarily aware of what to listen for. It's night and day. Delta-sigma from my Oppo and Emotiva sound great, but the multibit from the Yggy makes then sound digital by comparison.

The Yggy can do PCM up to 24/192 for all inputs, and 24/192 is certainly hi rez. I do not believe the Yggy "rolls" off on any end. Also, the Wyred 4 sound is using an older ESS 9018 chip and my Oppo has the latest ESS 9038. I'm no longer interested to listening to the Sabre chip as I prefer the Yggy, however, I agree that preference and not merely better or worse can guide that decision.
