Simple Philosophy, Simple Design, Simply Brilliant

This amp continues to blow us away with its incredible openness, honesty and resolution. But the thing that really has us stumped is how you can make a Class A amp that sounds as good as it does for such an affordable price!

Pure Audio have a philosophy; Keep it simple.  
And that is absolutely reflected in this amp.   Just a volume knob, 5 input selector buttons, a master power switch and thats it.  No EQ or balance or ad on features, just a really good sound amplifier with a volume control.

This amp is actually a Dual Mono-block amplifier with completely seperate audio paths and 2 power supplies for each output stage!

Offering 4 line level inputs, one direct input (bypassing the volume control) and with simple, direct push button source selection and full remote volume control, the ONE Integrated amplifier is set to become the heart of your music system.

Our ONE integrated amplifier sounds neutral or slightly tube-like and delivers a performance that is relaxed, pure and involving. Class A performance is maintained under typical domestic conditions and there is headroom to spare for demanding material. Difficult loads are easily driven.

As with our other products we have included a fully regulated, high-current power supply (you will rarely find this in competing products). This provides an optimum low impedance, low noise environment, from which the amplifier can deliver its very best.

While offering Class A operation we were conscious of the need to avoid energy wastage and so designed the amplifier to fall back automatically to a low power standby mode when not in use.

The amplifier’s Class A operation is automated through both remote control and signal sensing.

Our universal chassis design, constructed from heavy aluminium, stainless steel mesh, and supported optimally on three custom designed feet, presents a beautiful architectural look and fully supports our musical goals.
