The PSU1 is the linear audio power supply supplied with our flagship phono stage preamps and headphone amplifiers. The PSU1 linear audio power supply has a stabilized output voltage of +24VDC at a down-rated 200mA.
The PSU1 can be used to upgrade the sound quality – sound-staging, more vivid tonal colour and bass detailing – of all Graham Slee phono stage preamps and headphone amplifiers supplied with switch-mode or linear plug-top power supplies. Upgrading to the PSU1 has the effect of taking your Graham Slee phono stage preamp or headphone amplifier to a higher level of musical performance.
