First thing I thought about was how neighbors would not allow for loud listening. I sound proofed my dedicated room so I can listen as loud as I'd like.
Audiophile junkie - awesome vid about NYC million dollar system today
Audiophile junkie is one of the better YouTube audio guys despite having videos that seem too long at times.
Today he had a video highlighting 2 remarkable systems that was showcased inside a really nice townhouse in Greenwich Village New York City. Horn speakers, very high-end components and lots of Viva amplifiers were in the systems. A very comprehensive walk-through of the system. A worthwhile video to spend time with, highly recommend.
