I've been using the DIY Paradise Ultravox (ADUM4160) to isolate the USB connection between my DAC and computer:
Ultravox - SGD70.00 : Welcome to the diyparadise e-store!
The Ultravox and downstream DAC are powered via an SLA battery connected to the Ultravox. There are a couple problems with this setup and I'd love to get your advice on fixing them.
Downstream USB Connection:
The USB connector on the DAC side of the Ultravox is a female A type and the DAC has a female B type. I've been using a USB cable between the DAC and Ultravox but I'd rather plug them together directly. To do that I need to replace the Ultravox's female A connector with a male B connector but I can't find a USB male B connector anywhere. Do they exist?
Power Supply:
I tried switching from the SLA battery to a series of AA NiMH batteries and the sound was substantially worse. The sound was overall much weaker and thinner and lacked bass. That makes me think I could do better than the SLA battery with a very quiet linear power supply. Does anyone know of an available linear power supply which would be suited to this?
Miscellaneous:
Can anyone with audio DIY experience spot any other possible upgrades or improvements that could be made to the Ultravox. Maybe replace the capacitors with Black Gates? Thicker power leads?
