I own 2 Krell KSA 250s and a pair of MDA 500s and have just double checked the owners manuals and according to the manual Krell has developed circuit topologies without fuses because they impact the sound quality. Instead they developed their own proprietary circuitry that self monitors the amp and will shut the amps down if their is a problem. I would be surprised if they would abandon this technology in more recent amps. Krell amps were developed to power up the legendary Apogee speakers and will play into a dead short. Some have even suggested one could arc weld with them. I would have copied and pasted from the manual directly but was not allowed because it is PDF form.
One might conclude that while the use of fuses is required to protect our expensive audio
equipment, it is not in the best interest of the components sonic potential,
thus the need for higher quality fuses to counter the effects of the fuses.
In fact many audiophiles have wired around the fuses or installed solid pieces of copper in place of the fuses for their systems sonic benefit. Of course this is risky, you could blow the hell out or your equipment! So I'll be safe and have better sound by buying audiophile fuses.
thus a better quality fuse that both protects the circuitry and p
