Hey, just listening a bit this morning. Another quick impression is that K 64 better in every way to ty hi-z32 but bass, which is more pronounced on ty hi-z 32, and maybe i shouldn't even say better, cuz im not sure bass quality is better on ty hi-z 32ohm, k's 64 ohm performed better an bass shaker test, its just not as immediatly pronounced. I think i was just excited about the ty hi-z yesterday cuz they sounded so good right out of the package...but I'll post another comparison chart sometime. i Have a bunch of $5-15 buds now. Fareal 32ohm ( http://tinyurl.com/gmlptmg ) are good as well, and the best cable out of any earbud imo . The differences are so subtle amongst all the buds, and when comparing more than 2 it becomes exponentially more difficult. Also, while im not entirely a burn in believer, I have found my ears get accustomed to sound signatures over time and what once sounded (eg) harsh or detailed or mid centric can later sound smooth, normal, or high/low, etc. I really do love the earbud renaissance going on but i might have to cut back soon, i have too many earbuds!
