@mojo555 there is a possibility that your system has a fault, you have had a few Audis in the past, so how does it sound in comparison, if you are not happy take it back to the dealer for a check
However, if it does not have a fault it's interesting now that there is only 2 options for sound system "Audi" or upgrade to B and O that the lowest spec is now the sound of the devil and there are shouts of " how can a premium brand install such rubbish".
Pre face lift there were 3 options.
Standard - which was truly rubbish unless you never listened to the radio or only listened to LBC or Talk Sport
Audi *** - which was good for most but got the criticism of some
B & O - which was God to but even then got criticism from the FLAC (whatever that is) v MPG format brigade.
First world problems I think, or a bit if human nature and marketing snobbery and not wanting the lowest spec on anything...that's why most of us are driving or aspiring to driving S3's...
Btw..I have *** in my PFL which is totally fine for a car ( I like to hear the engine occasionally) but is not as substantive as my BOSE sound touch system in my living room, but I can't drive my living room!!!
