Product Description

After years of relying on other equipment to drive Grado headphones, you can now listen and enjoy headphones through Grado Labs' Reference Headphone Amp, the RA1. Designed for state-of-the-art performance and specifically to play Grados, the RA1 will allow you to hear your headphones like never before. This 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.

By	T. Richards - See all my reviews (REAL NAME)

I wired this to my imac to listen to my Grado headphones. There is a fullness, not volume, but full sound. I also have a pricey set of B&Ws to compare. I dont regret the purchase. Not to mention the mahogany amp looks good on my desk.
