What Headphone Amp or Amp specification do you recommend for the HEDDphone?
The HEDDphone needs a lot of current. We recommend HP amps with at least >1 Watt/32 Ohms. A powerful amp makes a big difference even at low listening levels.
Some amp designs need a balanced connection to provide the highest level of power.
In-house we use the SPL Phonitor 2/X and RME ADI 2 headphone amps.
