Wanted to mention, as I have dived head first into my new Xe6, the Unique Melody umbrella/petal tips (I don't know what they're actually called) are doing very nicely!! They're really thin, they seal, and they get that Xe6 nozzle very deep! I use them with my Indigo so thought I'd try them here, too, and damn, they rock! Everything just sounds better and the KB is right up against my concha. For me, better than the Azla or spinfits.
Honorable mention to the PWA FT cable I've had for months, that nothing else sounded right on, until Xe6 came and stole the freakin show! This is a lovely pairing and I'll compare it soon with a Code 23...battle of the coppers!
Can you order more of these? Curious to try them!
