Manufacturer 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 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.Product summary
The good: Audiophile-grade headphone amplifier; elegant solid mahogany case.
The bad: You'll hear a loud pop through the headphones when you turn the RA1 on or off; only the RA1-HG model plays loud with non-Grado 'phones.
The bottom line: This remarkable little amplifier brings out the best sound from your headphones.
