Building a New Listening Room on a Budget


My wife and I have been considering our next home, and recently signed a PA agreement with our builder.
The basic layout of the house is set but not finalized, which should be done within the next week.
I will have a dedicated room for my audio needs.  It measures approximately 25' x 14', and is not a perfect rectangle.  Doing my best to describe it, there is a 14' x 14' square section on one end and a 11' x 9' section on the other.
I plan to set up in the larger section, and use the smaller section for record/music storage.
The utilities room for the house is in the adjacent room, and I plan to have the internet router in that room and run a LAN cable from there into my listening room for streaming purposes.  I already plan to have at least one dedicated power line installed.  Should I add a second?  And, should I do 20 amp or 15 amp?
I'm planning to insulate the ceiling and walls adjacent to other rooms inside the house to avoid disturbing my family with the noise.  The floors will have carpet and walls will be traditional drywall.  
Beyond these things, what should I focus on that will not cost a ton?  I have read Robert Harley's article on his dream audio room build, but he spent way more that I'm willing to.  If I had to put a limit on it I would say around $10K.  
What other areas should I focus on?  
Thanks in advance!

Thanks to all for your responses.  Very helpful!
Ruminating on a few things:
- Stupid question:  Can 15A components be plugged into 20A outlets without a power manager?  I have a Niagara 7000 and know that it is fine with 20A or 15A, just not sure about plugging in directly to these outlets.
- The room is in the basement, partially underground.  Two walls are outside walls, brick covered with studs and drywall.  One of these walls will have an egress window, the other will have only dirt behind it.  The other two walls will be barriers between inside rooms of the house, one of them being our family room, and the other being the utilities room.  I'm thinking to insulate both of these walls with rolled insulation.  I could spray foam them at higher cost but wondering if it would have any benefits?  Ceiling will also have rolled insulation unless I hear of a better way.  BTW, above this room is the walk-in closet of our master BR.  I do not want my wife to complain about the noise at night.  At least it's not directly below the sleeping area but we all know how annoying it can be to deal with noisy neighbors in apartment settings.  That low rumble that persists.  Don't want that.
- 5/8" rock is a great suggestion.  I already requested this with the builder.  Sheetrock guys will probably curse me.  
- In my current room I have the equipment rack to the side of the speakers rather than between them.  I have heard this produces better sound but not sure I can attest to this.  I do have the option of running it this way in the new room as my speaker cables are 16 feet long.  Not sure if this is important to consider but thought I would elaborate.

Thank you!
