@jacobsdad2000 Fuses limit power changes since they must have a small resistance. This generally isn't a problem is the load is fixed. So I'm not very concerned about fuses in the DAC.
I would be concerned about that many fuses in a tube amp. I wouldn't be happy because thes fuses are likely limiting my dynamic response.
There are some exceptions. Fuses on the heater circuit don't generally affect sound so if you've got fuses on your heater circuits and avoided a fuse to the power circuit, then kudos to the engineers. If the fuses are in the signal path to protect the output transformers, that's the worst place for a fuse.
I also say the fuses were not put there by the engineers, they were requested by the bean counters after an expensive warranty repair came in. And the repair was almost certainly caused by operator error--putting the wrong tubes in for example.
There is a reason that audiophile fuses are selling like hotcakes. Asking about fuses in the design before buying an amp will become a thing as buyers become more aware.
