I haven't heard this particular chip in a top flight implementation (I have an old Cambridge Audio amp which uses it but that implementation sucks). Its brother and sister chips with similar internal design sound wonderful when given a decent PSU. Suggest you uprate the PSU you have on those PCBs you're showing...

Why did you choose to build an obsolete unavailable amplifier when there are thousands of available alternatives?
