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. 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. The RA1 is available in an AC
version or 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.
Also available the RA1-HG (High Gain). Now headphone enthusiasts can utilize
the RA1's sonic qualities with a wide selection of headphones. The RA1-HG is
designed to drive headphones with impedances of 100 ohms or more.
