Currently have the Sony Signature Series MDR-Z1R headphones, with the TA-ZH1ES amp/DAC and the NW-WM1A portable audio player:
In the past I’ve had Sennheiser HD650 and HD800, Grado GS1000, Stax 007tII and Audezé LCD-3. I also currently have Sony’s wireless noise-cancelling headphones MDR-1000X and Sony IEMs XBA-N1AP for out of the house.
I’m looking to get a Roon Nucleus soon to use with the USB input on the TA-ZH1ES. My Leben CS300XS is also a great headphone amp, so I have a choice of solid state or valves in the same system.
