First I would contact Benchmark and make real sure that the fuse is the correct value. If it is DO NOT put in a larger one (otherwise you WILL cause more damage). You will need to have the DAC serviced.
On the other hand check with panamax and ps audio to ask if they warranty devices hooked to their equipt that has problems due to surges etc.
