The two stages of audiophilia


1. Compulsively and fanatically build the best audio system you are able to and can afford.

2. Sit back, listen to MUSIC and enjoy your system.

Acoustic controls and treatment are not "tweaks"....

Tweaks are secondary facultative additions to improve a system...

Acoustic treatment and controls are fundamental, not secondary, and exceed in potential positive improvement almost any gear upgrade even the speakers sometimes...

I spoke here only of the most important embeddings controls  the acoustical one.... It will help also using the other 2....
In 30 years I haven’t made it past step 1.  I may need a 12 step program to get out of step 1.  
My first ten years or do were 1). Then a couple years of tweaking. Then 2). Over the decades I became much more orderly with 7 - 10 years of enjoyment, Then 1) as I could afford (on not afford as my partner would say) tweaking and enjoy for another 7 - 10 years. This has resulted in long, wonderful periods of audio bliss and maniacal upgrade cycles. Now retired with a better sounding and looking system than I though I could ever afford, I am very happy.
