While I agree with you 100% on the value added if he enjoys the purchase, the line conditioner and fancy cables are hard to make a case for.In what sense are they "bad decisions"? It depends on his financial situation and whether he enjoys the purchases.
I think it's safe to say given a check for what ever amount he spent, we would buy different gear and "know" we had made a better choice... as he "knows" he made the right choice.A handsome setup for sure and I'm sure it sounds very nice.
But all that money and he's still restricted to 2ch's
That's a shame.
Personally I question his acousticians... there are no diffusors that I can see and only a number of 200Hz and up absorbers and minimal bass traps. Yeah maybe, but probably not.
