Here is one thing I would like to know if you play an MQA CD as a regular CD and dont unfold it are you getting less than redbook CD quality because there are less bits involved? It plays as a 12 or 14 bit CD?
My opinion, which I think the real answer should be an own individuals experience, doing A/B testing.
That said, I believe they are definitely not worse than RBCD which some remastered RBCD's are definitely worse than earlier CD versions.
I believe, that because they are made in Japan, from current engineers, from master tapes, that yes, they should be considered better when apples to apples.
One note, many of the MQA discs are the same music as previous Japanese SHM SACD's which gives you a little bit of a clue.
When I purchase an MQA disc I make sure it is not one of the many SHM SACD's I have as I feel it would be a waste of money, risk vs reward.
Someone said above that mastering is everything and I agree.
When I look for RBCD's via Amazon I always look to see if they have a earlier 1990's version, usually they are cheaper, and sound better than a 2000's RBCD, remastered with extra tracks.
What does all this mean, who really knows what the fuck it means, I am not interested in A/B'ing discs for a living, I'm not that good and nobody is paying me.
