Introduction
Alpha & Delta is a Singapore brand that features a lineup consisting of AD01, D2 and JAAP that targets different users. The D6 is a newly released iem that utilises their own technology, HDSS high definition. I would like to thank Lend Me Ur Ears for this opportunity to review their latest iem, Alpha & Delta D6. At the moment, you can purchase the D6 from http://www.lendmeurears.com/alpha-delta-d6/ .

How is noise cancellation?

The shell is quite small and the isolation is good.

Is the cable good enough to be an upgrade cable? (Specifically for the Fiio F5, I’m using it with Spinfit CP155 but still find its treble wanting)
LikeLike
Do you mean that the treble is too bright?
LikeLike
Nope; rather, I find it rolled off, especially in the upper treble registers. I heard that silver-plated cables tend to “open” the treble and soundstage, but I’ve never dabbled in cables before, hence I need some sound advice :p

Hi, you can try this cable, Penon OS849 or Han Sound Muse II in order of brightness.

Alright, I’ll go for this one! Actually my friend did recommend the Penon OS849, but unfortunately that one’s beyond my budget. Thanks!

This is the detachable version of D6’s cable.

True that. It became available some time after you wrote D6’s review, AND I am so pleased that it did –an excellent match with BGVP DMG, not only with D6.
