Thank you! These links paint a much different picture than the WaPo story, which is bordering on dishonest with phrasings such as "$1M stereo" and "modest split-level ranch". From these links, this project seems to be more appropriately described as a fancy and bespoke DIY home renovation. That wide two story shot looks quite gorgeous, independent of all the acoustic treatment. And yeah it is a sad fact that if you do extensive customization to your house the market doesn't really care, while new builder grade crap plus a coat of beige paint will be enthusiastically rewarded.
