Do you collect DVD/Blu-Ray/4K Blu-ray? Do you have a wall of discs? Joe doesn't like physical media! Target had a big sale on Monolith speakers! Arendal in house at Joe's place!

REW goes to 5.3, with lots of updates! Room EQ Wizard is a free program for home theater testing, but do send him some money if you get use out of it!
