The RA-1 is a state-of-the-art battery powered headphone amplifier that offers the deepest sonic blacks due to a DC power source and allows you to hear your headphones like never before. The RA-1 is machined from a solid block of mahogany and measures 5' wide, 5 1/2' deep and 1 1/2' tall and weighs in at 12 oz.
The RA-1 is powered by two 9-Volt batteries that will drive the amp for 40 to 50 hours of listening pleasure. And the sound? Just like all Grados: warm, smooth, full-bodied, non-fatiguing and rich. Hook it up to any line source (portable or in-home) and drive your Grado headphones to their full potential.
After a long period of absence in the UK, the RA-1 is thankfully available again and is arguably the best battery powered headphone amplifier ever made.
