I'm currently sourcing new furniture to store my headphones and audio gear (currently at four full-sized phones, three IEMs, some 30-40 CDs and a few DVDs/BluRays). I expect this to grow, especially as I start buying DACs & amps. My original thought had been to use one of those enclosed entertainment centers and build a couple racks across the TV area for headphones. Shelving below can store DACS & amps and peripheral storage can house CDs and DVDs/BluRays. Build a couple glass doors to make it enclosed and voilà.
What furniture you guys use to store your headphones and audio gear. Did you buy it? Did you make it or mod it? Do you run actively-used gear through it or just store not-in-use gear in or on it?
