S2 version of Connect?

No one is making a case that objective measurements trump all else where home audio is concerned; just that these are useful as a guideline on what to expect, to shortlist kit for testing, and to match kit assembled from components from different makes.

So if a Connect and Port, in a listening DBT threw up sound differences in fixed level mode at their digital outputs, the fact that both are measured to be bit perfect would be something to investigate further - the DBT may be defective, or one of the units may be. 

Needless to say, there isn't even ONE such DBT carried out and published anywhere in the world till now. Subjective opinions, there are a few, on both sides of the debate.

All that a DBT being referred to here seeks to do is make sure that a listening test isn't biased by psychological factors - it still remains a listening test where the only “instrument” that is used are human ears. In addition perhaps to use an instrument to ensure that sound level matching is done to the extent needed for a valid result because the ears are not capable of the precision needed to do this while the brain can still be thrown off by lack of such precision. But the test is still a listening test. And the media reviews don't ever come close to such testing before passing subjective judgements based on notoriously faulty human memory when it comes to remembering how some other kit sounded when heard in the past.

As to Port features, I merely said modernised:-). Modern isn't always better and while I have not used a Port, this may apply here as well.

Yes.

Thanks all. As it turned out it appears I lucked in - my old Connect had died about 5 months ago, and I bought a replacement - which is able to be updated to S2.
