Selling this barely used Meier Audio Corda Rock. Just got this as a gift on 18th Jan 2019, total usage stands at less than 5 hours in total. This is a great entry-level amp to pair up with your headphones/iems so I suppose if you're a HD 598, HD 6XX or other entry to mid-level headphone user, this would be perfect for you. The Gain on this amp is adjustable to give your headphones greater volume or fidelity. This headphone amp is listed in Innerfidelity's Headphone Amps Wall of Fame and is by far the cheapest amp on this wall. The next cheapest amp costs US$699 compared to the price I'm selling them at - 175 USD with Free Worldwide shipping! I'll also be throwing in a few accessories as well to get you started straight away. I will be including an IEC Power Supply, a Micro USB-C to 3.5mm input and a 6.3mm male to 3.5mm female adapter. The Innerfidelity review of the Corda Rock describes this as a neutral amp, with very slight warmth and very slight softening of the high end.
