Astell & Kern is widely known for their superb line-up of DAPs. But for those of you looking for a compact and simple USB DAC solution, just like the Dragonflys, the Korean high-end manufacture is soon launching a nice little toy. Their PEE51 USB-DAC has a Cirrus Dual DAC inside and a super solid metal housing. It feels and sounds just outstanding and at 119 EUR (yes, you’re right …), it is the bargain of the year!
