Here is a pic of my vintage "catch all" room. Made for mixing, matching, build it up and tear it down kind of fun. It is a real plethora of audio: JBL, Altec, M&K, Carver, Krell, Pioneer, SAE, Yamaha, Teac, Mission, Parasound, Sumo, SST (spread spectrum technologies), Bottlehead and a lot of DIY. There is more in the garage and shed that I should just set up in this room. If for no other reason than to be able to look at it. Just things like Apogee Duetta Signatures are large and take up floor space.
