I am a music listener rather than a collector despite having 25,000 LPs, 7,000 CDs and 7,000 78s. I have a high end system but not close to SOTA. My listening room cost twice as much as my equipment and was custom designed by Acoustic Fields. It is a multi-"laminated" design with no openings (doors are also 16" thick of same design) with multi-cavity interior, activated carbon chambers. Basically, built-in bass traps. Bass is deep and smooth. The room is tremendous. Looking to upgrade to Von Schweikert VR9 Mk II speakers soon.
