I know this has been done to death but can anyone recommend a good, loud headphone amp. Or an alternative which will provide loud headphone mixes. We're currently using a Beh****** Powerplay HA4000, and while this is adequate and provides the amount of separate mixes we need, it never seems to be loud enough. Particularly for the doom metal clients we seem to attract. We use 2 auxes on our DDA to provide either 2 Stereo mixes or 1 stereo and 2 mono mixes. This is easily accomodated by the HA4000, so any alternatives just need to be equal in spec and louder. Looking forward to hearing your views. ps Did I mention it needs to be loud?
