Primare Audio R15 – MM/MC Phono Preamplifier

"... They excel at giving your music real definition, and they have one of the silkiest presentations at the high end that I’ve heard in a set of on-ear headphones. I found they did real justice to almost any music I fed them, and they’re beautifully balanced at medium to full listening levels. Another win for Grado."   Crutchfield, Woody Sherman   -- RS 1x Ever wondered what hardcore audiophiles are hearing, and that you might be missing? The Grado RS1x is the point of no return so be warned, cross this threshold and you’ll never enjoy mass-market headphones again. Once you’ve experienced this elegant audio masterpiece you’ll grasp the reference. The RS1x from Grado uses a different species of handcrafted mahogany from our previous models. The earpieces utilize an intricate curing process that optimizes the tonal quality while giving them a new look. The RS1x places a 50mm dynamic transducer and an 8 conductor cable design in an open-air configuration. The result is a smooth, controlled, and coherent sound with detailed dynamics. Frequency response ranges from 12-30 kHz and the drivers are matched to 0.05dB. Weighing 9oz, the headphones are an example of the wonders of Mother Nature with a gorgeous light mahogany look. The RS1x is a masterpiece in the Grado collection.
