Hey guys, I'm looking to sell my Meier Corda Aria. It's number 299 of a limited edition run of 500 units. For those that don't know, Meier is a German company that specializes in headphone amplifiers. They are very high quality units, and paired with good headphones, the sound is phenomenal. The Aria incorporates a USB digital audio converter that bypasses your computers sound card. The result is amplified audio that is clean, clear, and strong. The first time I heard it, I was simply amazed at that massive improvement over my computers own audio. I'm selling my Aria because I'm not using it as much as I once was. I'm simply not sitting at my computer as much as I used to. The unit is in flawless condition. When new, the asking price is $450. I'm asking $350 shipped in the US. Contact me if you have any more specific questions.
