Max, seems like you've followed roughly same trajectory as me. About 23ish years into the hobby. Just finished building my HT about six months ago. An unexpected dream come true. Consistently good fiscal decisions in life can compound and eventually yield an audio system that is remarkable.
Of course, your master stoke of genius is the Xbox! Makes all the effort worth it - gobs of fun! Currently, I'm stuck in a section of Halo 2. I rant and rave against it, but I keep going back... Video games with 5.1 surround and projection, WOW, what fun! That's become one of the main joys of the big setup.
I used to have a Cal Audio DAC Sigma II and later an Alpha. Cal Audio makes good sounding equipment.
Are any of your family members allowed to venture beyond the listening chair? :)
