Short of a transformer so your amp sees something more healthy than those 8 ohms, I don’t know. The problem is twofold - these are not very efficient (80dB/mW vs 105dB/mW on the HD600) so they need actual power to work. The 8 ohm impedance just means that the way the power needs to be delivered is super inconvenient for most headamps. Think of the Para more like a 110dB/W speaker.
