Thank you. My listening times probably are 80% HE-500 and 20% HE-4, being the 20% for specific fun listening or gaming. For me, the real deal for serious listening is the HE-500. Since i already have an Sabre DAC (ODAC) and a warm hybrid amplifier (EF5), what can i expect for the NFB 11 for the HE-500 vs my current setup? Will be a good idea to choose the NFB 15 to have "another flavor" for the HE-500 and keep my current desktop gear?
I'd really go with the NFB15 if I had the ODAC and EF5 myself.
The NFB11 should be a bit too edgy and bright for neutral headphones, like Hifimans.
