Selling my Hifiman EF-6 which i have used with my Hifiman HE-6. Also offered the HE-6 with the EF-6 combined but now will try to sell the EF-6 separately first. The amplifier is in great working condition, got the invoice but don't have the box anymore. If shipped i will make sure it's well packed. Pickup or a listing session would be possible in Noordwijkerhout in the Netherlands.
