What's your profession? Age?

I am a 47-year-old Biomedical Engineer/Manager working for a national hospital group. System cost is around $30,000 including room treatments.

I am the manager of the Biomedical Engineering department for a group of hospitals in central Texas. I am 45 years young.
My system is comprised of all Melos tube components, and Vienna Acoustics Mahler speakers (soon to arrive). I would estimate the list cost of my system at $22,000. However, this is not an accurate number strictly speaking. Many of the upgrades done to my system over the years have been bartered. I also build furniture a hobby, and have traded those services in making speaker enclosures for several acquaintances that were designers, in return for components that they either designed as well or had on hand. Given the cost of running two very expensive hobbies without over stretching my wife’s patience, this was the best solution to both issues so to speak. So strictly speaking, I have likely spent 1/2 of the above amount. I suspect that trading other talents for equipment is not an uncommon practice with other members of this group.
