Taiwan-based IEM brand DUNU has consistently impressed with its offerings and one of its more popular products is the SA6—a member of the brand's Studio line of IEMs that uses six balanced armature drivers. The original SA6 released a few years ago still holds a place as a reference item in the $500-600 price range today and this success was followed up by a limited edition SA6 Ultra which only had audiophiles wanting more. Today DUNU and HiFiGo released the new SA6 MK2 which aims to build upon the SA6 and improve it further. Updates include a new ergonomic shell design paired with wooden face plates, a new Hulk Pro Mini copper cable with 3.5/4.4 mm modular connectors, a new storage case and ear tip collection, and a different tuning signature that can be described as neutral with a bass boost. There is a tuning switch onboard to further up the bass for those who want it and TechPowerUp will have a review soon to test all these claims. In the meantime, knowing how popular the SA6 was and no doubt how this will too, the hand-made nature of the SA6 MK2 means those interested might want to order sooner than later if you don't want to wait for new batches to be made. The DUNU SA6 MK2 uses six balanced armature drivers from Sonion and Knowles and costs $579 from HiFiGo.
