Note that everything is "Subjective" and there are no standards for that. What may sound great for you may just sound nice for someone else.
Everything in a listening environment, room affects the audio. Is it a "live or "Dead" room. Furniture affects reflections of audio changing phase and sound level.
Your Brain interprets sound differently depending on your mood.
When was your last hearing test, when was the last time your ear wax was removed. Lots of variables to consider.
It's all about Music Appreciation and trying to analyze the detail your system can resolve.
What is interesting is with familiar albums heard on a less than ideal audio system, your brain will remind you of instruments or sounds that cannot be reproduced on lower quality systems.
So like all marketing media, everything is great and the best I've ever heard. Some people have never actually heard High End Detailed Audio and don't know what True Realistic Definition in High End Audio Sounds like to compare to.
So find a quiet room with no interruptions and really listen to what music is. You have to train yourself to hear the detail if you choose. Discuss what you heard and how it affected you.
So what annoys me the most? Battery powered clocks. 2 rooms away I still hear them ticking, even when I go to sleep at night. So I replace the quartz movements with continuous movements which are silent.
Note if you want to collect CD, find them in thrift stores and check the release dates and purchase the ones from the 1980s and 1990s before the compression wars ruined the dynamics on CDs. There is a website that lists the dynamics on LPs and CDs by release dates and may surprise you.
Remember a great sound system can sound bad in a bad listening environment. Even listening loudness has a sweet spot.
And as always, it's all "Subjective".
