Hi all.


I've just decided to pull the trigger on my first pair of high-end IEMs, and I decided (after agonising for several months) to choose the Heir Audio 4.Ai's over the Ultimate Ears 900. But I digress. Heir at the moment have the 4.Ai+ on sale for $478 US, a 20% saving over their normal price. The only differences I can see between them is the choice of two different woods for the face plate, and the Magnus 1 cable instead of the normal cable.


Can anybody with a lot more experience tell me, is this worth the $78 dollar premium over the base 4.Ai?
