It is my first time to sell things here . If u want we can use eBay to trade . And U can pm what price u want . This mp3 is the new version. I bought it in march 2014 . I need money for my lcd3 amp so I sell it . It is perfect condition . U can connect my email firstname.lastname@example.org. I lost the original box. Other things all here in the picture. And still have some songs in it.http://www.everythingusb.com/acoustic-research-arm1-21761.html
It is the review and introduction . The all new ARM1 not only boasts a Burr-brown DAC (PCM1794) but also makes use of Texas Instruments for the built in OP-amp (OPA2134) and headphone amplifier (TPA6120A2). I use it with rs1i. They are perfect better than ra1 + rs1i.
