2nd systems- who’s got one?

How prevalent are 2nd systems? My sense is that a fair number of folks have a 2nd system. I put together a very nice bedroom system- NAD 316 bee V2, Node (n130) and Wharfedale Diamond 12.2 on Monoprice stands. Cabling is DH labs (IC), Supra (speaker) and Audioquest (pc on Node). Frankly, I’d have been thrilled as a teen to have a system that sounds as good as my bedroom system
