I read a couple reviews, one on What Hifi that reviewed the K52 and another that reviewed all three in the series, the 52, 72, and 92. Funny thing the review of all three much preferred the cheapest of the series highlighted in this thread, the K52. I have some leftover Amazon gift card balance in this amount, but unfortunately Amazon is not in on the sale, I'll have to find something else to save (waste) $30 on. In the spirit of the OP I'm not posting any links, it's a treasure hunt, a Google adventure, you'll have to type in AKG K52 and hit the search button yourself. Let the games begin!
