Furman makes bigger, more expensive units. Look for LiFT and SMP.
Shunyata is also a good idea.
Power cords need not be very expensive but using shielded for digital/streamers that are near your analog is a good idea.
Keep power adapters outside your "clean power zone." or use a second strip for them. Especially good for network devices like routers and switches. Alternatively, use a power conditioner with multiple filtered banks like Shunyata or Furman offer.
