Hello again! I recently bought another pair of KEF LS50 from Amazon for $1,049.00 (link, seller is discount music: https://www.amazon.com/KEF-LS50-Mini-Monitor-Gloss/dp/B00EPDMDZ8/ref=sr_1_1?ie=UTF8&qid=1482298591&sr=8-1&keywords=kef+ls50). I noticed the item says used but the description says...

Posting this on a few forums, need some KEF advice.   Ok, so after hooking up a few mismatched speakers to test surround sound for my room, I'm sold. The Frankenstein setup is as follows: Front LR Kef LS50, surround LR Pioneer ebs73, sub SVS sb12 nsd, and center...one of the two svs ultra...

Had the M50 for about 6 years now, powered by an O2 DAC/AMP. Haven't really been compelled to upgrade. Would the M70 be worth my money?   Foam kind of corroded on the top, that's my only complaint. Will probably go for something with leather ear pads for longevity.
