Fsmith - The Off-Ramp 5 should work fine with your USB cable, and it will likely improve on the USB interface in the Bricasti to boot. OR5 can be upgraded later to Off-Ramp 6 or Interchange Ethernet interface. Both big upgrades.
If you want Off-Ramp to sound the very best, it needs the Dynamo power supply option and my BNC-BNC coax cable option with RCA adapters. This cable is a true giant-killer at $250.00. These can be added later if you only want to get your feet wet. 30-day money-back, less shipping.
