Acoustics

Soliciting insights on "Acoustical Treatment" at the construction level.

I am in the design process of a new home. One of my priorites for this build is a "Dedicated Audio Room". It is what I would classify as Medium in size 21L'x16W'x11H. Helmholts Resonaters have been designed and will be installed in each corner, dedicated circuitry and ground. I work in technology and have engineering resources I can leverage to optimize dimensions and venting to reduce "Room Modes", but not so much for Acoustical Engineering and equally if not more importantly, experience/ familiarity listening to different systems in different enviornments. 

Originally, I was thinking about "Reselient Channels"  around the perimeter and the ceiling, but my Architect believes "Acoustibok" is a better option.

My listening preferrence is in the 70/75 DM range. High sensitivity speakers, Class "A" Amps, Significant focus on "Very Low Noise Floor". I like Cool Jazz, Instrumentals, Prominent Vocals and some Rock from time to time.

There is a threshold between Room Conditioning and going too far. If it makes sense, I would like to retain some liveliness (80/20) and not take the conditoning all the way to a recording studio state. My fear would be going too far and creating a dead space.

Does anyone have experience with either Acoustiblok or Resilient Channels, their charachteristics? I am also open to other suggestions.

Thank you!
