I have a first generation Bluesound Pulse that does not have headphones output. What it does have is two USB ports: USB 1 x Type-A (Fat32 or NTSF formatted) port for connection to USB memory sticks and supported peripherals 1 x Type-B (mini) for product servicing Would Meridian Explorer 2 work with it and my headphones? Also, if it does, would I be using Pulse's internal DAC, or Meridian's? They are both MQA capable. Thanks!
