You're assuming a 10k transport is technically any better than a cheaper one, rather than just in a fancy box with more margin and lacking economies of scale.
As long as the cheap one hits the protocol spec theres no reason it should sound any different. If it doesn't meet spec then all bets are off. Just like if the expensive one doesn't reach spec.
Your perfectly entitled to hear whatever you want, I'm not saying anything about what anyone else hears. Only what I hear with my kit.
Amazingly even a cheap dvd player can get a higher bandwidth and data rate right, without drop out or glitching, yet some think cd transports can't manage a less taxing version of the same thing.. you wouldn't keep a broken dvd player, why would we accept a transport that can't achieve spec?
If the eye pattern is within spec there really is nothing else to discuss.
