Well Holo Audio checks off every other snake oil claim w.r.t. May DAC (but can't figure out a buffer) so why not add fuses in there? Starting off with NOS at redbook rates is already a flawed presentation. I did get a kick out of their marketing. That was some seriously thick spreading of the brown stuff.
