I think if you ask a question like this one about your hobby you should find a new hobby that you do enjoy and don't need any approvals. It's like "badge we don't need no stinking badge". I could be wrong, I was wrong once before.
How do you know when a stereo sounds good?
When do you know your system is pleasing to listen to? How do you conclusively prove to yourself that your system sounds good to you? How do you determine that you enjoy listening to music through your stereo? Do you have a suite of measurements that removes all shadow of a doubt that you are getting good sound, sound that you enjoy? Please share.
