Designed for state-of-the-art performance and specifically to play Grados, the battery powered RA1 will allow you to hear your headphones like never before.
The RA1 can be 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.
