Summary: The first reviewer mentions a USB port. There is none on this amp. Therefore, it is impossible to hook up with my current speakers. I'm in the process of looking for some speakers that it will work with and have not found any yet.
Summary: This product worked as advertised for the first four months of light usage. Then I started to use the DAC for 8+ hours a day and sometimes just left it on. After four months, the unit now gets hot after a 5-6 hours of use, then produces a high pitched hum.
