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.
