Hi Audiofreak, I bought the headphone amplifier HA400 and the microphone amplifier MA400. However, the output signal of both is too weak to drive a headphone via an extension cable, even if it is only 2m long. If you plug the headphones in directly, the sound is fine. Has anyone experienced this? I am looking forward to your feedback!
