Chadnliz, I'm glad you're enjoying the room! It was a dream for you, so it's immensely satisfying when it call comes together.
However, just to develop the argument (not at all in the negative sense; Chad is a nice guy!), I'll disagree with you (just for fun). How long have you been in your room? Less than three months, I believe. You're not even out of the honeymoon phase yet. Just wait...until you get the idea that because you're in this fabulous room upgrades will sound better! And indeed, they have for me; i can't say that my enthusiasm for good gear has been slowed at all by the room. In fact, it may have increased, because now I have an ideal environment to hear the equipment much better.
How much debt do you have after your project? If none, then you are truly blessed. But, I sure wasn't hyper on upgrading when looking at repaying thousands for the construction of the room. Once that was out of the way, wala the Upgrade Bug bit again!
Let's see if in a year you're as completely content as you are now. Knowing your history on Agon, I'd say that you will be back to your old tricks of looking for upgrades in the not too distant future.
It seems to me that there are two types of audiophiles: The one who buys and listens for years, and the one who is always on the upgrade path. My guess is that for those always looking for new toys a dedicated room, after dispensing with any associated debt, could fuel the fire! I wish it were true, my friend, that the room would cure "Upgraditis" but alas it does not.
Typically, the more money people spend on luxury goods, the MORE people want to spend. It's very encouraging to see all the responses of contented people, but I would suspect that's the exception in the larger population rather than the norm.
My hope is that people keep balance in their lives, and not overspend in audio or any other indulgence to the point that it disrupts more important needs/goals. If one lives within their means, then upgrades are all the more a joy!
