Yeah after owning the 12 and having the 13 for a few days, they are two of the best under $100 and would go for way above their price if they were in the big retail market. The 13 is def improved over the 12 in overall sound but I'd only recommend the 13 to 12 owners if they have the money and MUST hear it...or do what I did and sell the 12 for some money towards the 13
. Slightly less massive bass but with better texture & controll AND the treble in all areas has been improved, including resolution & clarity. I don't find it as Dark though as the 12 (as of right now with about 24 hours of burn in)
