I've seen/heard this in $100 units from Schiit. Not to mention the poor hand soldering job that cost more money because a human did it in America.
Their $100 units are some of the best testing amps/dacs in the price range, so even from a purely subjectivist standpoint they make stuff that generally works pretty well. If you're encountering issues, then they will usually make good on it.
The stereo imbalance is just something you're gonna see at basically every amp at that price point.
