In short, when you get a Life Changing Experience, then it sounds good.
This is called a circular reasoning... This is a publicity motto... Sorry....
This is even used for decades to sell new upgrading product...
i always liked myself all my pieces of gear, one after the other all my life....But was never satisfied really... Guess why?
The only way to know if your system sound at his potential working peak, nevermind the gear, is by acoustic control...
After that all your albums sound interesting, all of them reveal the acoustical choices made at the recording time...
My worst album acoustically are now revealing and interesting...
If you look ONLY for very good audiophile recording it is a sign that your system dont worked at his potential working peak YET...WHY?
When your audio system is under control, all albums are suddenly musical in their own way, with specific acoustical choices and trade-off made by the recording engineer and even the bad one are interesting to know...
Music through sound and sound through music....Not one without the other....
