Headphoneus Supremus
Two possible next stops for you and HD-600:This headphone continually knocks my socks off. Currently running it with a Forza Noir MkII cable from the Singxer SA-1 fed by the SMSL SU-9 dac/xDuoo x10T II (transport) combo. Best i’ve heard, and I’ve owned quite a few newer/more expensive headphones
1. Custom Cans UK driver backweight modification: $70 approximate.
2. Schiit Audio Valhalla II output transformer less tube hpa: $349 + shipping. The Valhalla II can handle high and low impedance hps. I own it, with three other tube hpa, and use it with Beyerdynamic DT880 at 600 ohms to Audeze LCD-X at 20 ohms.
