The two stages of audiophilia

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.  

Read about acoustic....

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.
