So far I am impressed with what the HD820’s can do. A continuation of Sennheiser quality and comfort for sure. You’ll definitely need an Amp and Dac to drive this headphone. I am running them on a Hip Dac 3 with no issues. The team at Moon Audio was outstanding and I can recommend them for your audio journey!
