If I could have only one IEM and put all my eggs in one basket, I‘d be hard pressed to find a more stunning flagship than the Erlkönig and would probably save up to get what could very well be considered a real endgame universal IEM. Build quality is nothing short of perfect and fit and isolation are as good as it gets for a universal. The Erlkönig is technically flawless with fantastic resolution, a pitch black background which provides fantastic note contrast and class leading soundstage but more importantly every of its technical abilities is at the service of a very musical and smooth tuning that you can tweak to your preference. What more could you wish for?
Dunu DK-4001 – Thunderstruck!
If you’re looking for a hybrid with superb build and cable, class leading bass that is both fun and technically faultless, natural mids with slightly forward vocals and lead instruments and exciting treble then you’d be hard pressed to find a better alternative than DK-4001 for the price!
