After years of relying on other equipment to drive Grado headphones, you can now listen and enjoy headphones through our new Grado Reference Headphone Amp, the RA1. This RA-1 is Battery Powered for portability.

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

This new amp 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.

And the sound?
Just like all Grados: warm, smooth, full-bodied.

Unit is Battery Powered.
