The T+A PS 3000 HV Power Supply can be used on either the PA 3100 HV Integrated Amplifier or the A 3000 Power Amplifier.

Both of these products deliver 300 watts into 8 ohms (and 500 watts into 4 ohms) and are so well designed T+A discovered that simply increasing output power brought about no real uplift in sound quality, but their research and development did show that the stability of the voltage and current supplied by a mains unit is of crucial importance to the sound quality of an amplifier and an external power supply could dramatically improve upon the performance was configured in the right way.

When connected to either product the PS3000 powers just the output stages, allowing the products internal power supply to feed just the input stages, so the external PS 3000 is dealing with the higher current demand. The PS 3000 has twice the reservoir capacity compared to the PA 3100 or A 3000 when used on their own.
