I'll play. My desktop audio chain is a 2012 iMac > Audioengine D1 DAC  > Wireworld Equinox III ICs > Audioengine A2 powered speakers, with 3' of Anti-Cable speaker wire connecting the powered speaker to its passive mate. To me, cables are important components in the overall synergy of a system...

I've been very happy with Head-Direct. My PK3s arrived about 3-4 days after I ordered them. I haven't needed customer service myself but many have reported good experiences. And you're unlikely to find better prices anywhere else.

Just to throw in my $.02 worth, I've also owned both the Shure E3c and Ety 4p (with conversion cable), listening primarily to my minidisc player through the new Total Airhead amp. To my ears, the Ety's are far superior and more musically engaging. The Shures are very rolled off in the high...
