Not sure if posting in the right place so mods feel free to move if necessary. Is anybody on here using this amp mostly (or even exclusively) as a headphone amp? If so, what are your opinions of it? It has had favourable reviews in this regard from the hi-fi press but interested to know if any forum members are using the D3020 V2 as a headphone amp. I am thinking of putting a D3020 V2 in my man cave/office, and streaming via Bluetooth to the D3020 V2 from my laptop. As I understand it, Windows 10 supports aptX, as does the NAD. I would use mostly as a headphone amp, although I may also connect the pre-out on the NAD to connect to a powered Bluetooth speaker that has RCA inputs. My headphones are Sennheiser HD 579.
