Our take on the Grado RA1 (AC-powered) by Crutchfield's Dave Bar
Hear your Grado headphones like never before
No doubt about it, Grado headphones sound fantastic no matter what you have them plugged into. But just like great speakers, great headphones need high-quality amplification to perform their best. If you're connecting them straight into the headphone jack on your stereo, you could be missing out on a lot. That's because many manufacturers use low-cost, low-fi circuitry to drive their headphone jacks leaving you with a lackluster audio signal that can make your tunes sound harsh, overly bright, and one-dimensional. Grado's RA1 reference headphone Amp delivers the superior power you need to bring out all the performance your headphones have to offer.
Lovingly crafted just for your cans
Each RA1 is machined by hand from a solid block of mahogany for great looks to go with its high-performance sound. Connect it between your music source and your Grado 'phones to experience even more of the remarkable warmth, clarity and detail that made them famous. You'll hear farther into your favorite recordings for that "you are there" feeling while enjoying richer, deeper bass, clearer highs, and greater musical texture.
