Why did you purchase the equipment you have and what do you like most about it?

I researched in English and my wife researched in Japanese. We landed on the Yamaha NS-5000, which we auditioned and bought in southern California. I had sold my late mother's house after a succession of hassles so I charged a tip. All my other gear is refurbished or bought on sale nicer mass market stuff. 

magnapans in 1982 after I heard their top of the line tympani III playing. still have 'em. much later, some thiel cs.5 speakers, as they were the only models thiel made that didn't require a monster amp  to properly drive. they image like nothing else, not even the Maggie's can image that well. 

Lots of gear over the years. I finally decided that I would buy gear that pleases me but may not follow the idea of accurate sound. My system is flawed but it's flawed in the most pleasing way. I could not be happier.

When I was looking to upgrade my system I found a PS Audio BHK 250 amp for a really good deal at Upscale Audio.  I loved the sound so much that I just kept buying PS equipment.  I now have a set of BHK 300 mono's, BHK preamp, MK2 DAC and an Airlens streamer.  The only thing that isn't from PS is the Aurender N20 and my speakers which are Focal Sopra 2's.  If I could; I would buy the PS FR30's, I just can't swing that right now, but maybe some day.

To answer the question posed in the title, I purchased my present equipment because it sounds good, and I like it because it sounds good.  This hobby really isn’t that complicated
