So many variables with audio

Best to not make too many changes---just take and old cold tater and wait.....

Audio is the ultimate algebraic equation!

Any hobby worth having is laden w/ choices (a good thing).

There's only two variables, it either sounds good to you or it doesn't.

You get a million different answers, because of the many different experiences. I recently changed from an integrated amp to separates. My speakers sound significantly different now. So, if someone listened to my speakers with the integrated they would describe what they hear totally differently from what they hear with the separates. The fun and frustration of being an audiophile are the endless combinations that can make a system enjoyable or disappointing.
