Grado Reference Headphone Amplifier
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 RA-1 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. Two 9-Volt batteries
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.

was rendered truer, clearer, and more life-like than I had ever imagined

is such a nice job of product engineering by John Grado, I think it
earns a nomination for "Dudely Product of the Year
- Charles (His Dudeliness) Hollander,
to my RS1's through the Grado RA1 headphone amp is like
listening to a live performance, it puts you right there."
