They also have a 30 guarantee. Dont like it within 30 days send it back. But I have never tried this. I do have one of there iDacs from days of yore and liked it. And when I called about and issue they answered the phone and offered a solution. I may have to try their new Sona Amp some day. There older integrateds can be found on ebay for around $600
