Studio Power Amp 
Have found this amplifier to be of sound build with a clear and clean response. The unit is quiet and has never been prone to overheating which prevents any aural interference when monitoring a mix.
The output performance of this amp is 45W at 8ohms, this increases to 75W per channel when pushing through 4ohms. The dynamic range of the unit is from 10Hz through to 70kHz.
