Trying to do one stop shop since my listening requirements have changed. Several years ago purchased the iBasso D10 and AKG K271 closed cans. Didn't listen as much as I thought I would. But times have changed and I can go open. Any thoughts on a Audio GD NFB-2 DAC and Heed Canamp? Source will be lossless digital via optical from an Apple Airport Express. Searching for the best combo of price and peformance with the AKG 702. I haven't seen this combo discussed.
