The answer to the initial question is: yes. Long ago, I bypassed the fuses in Acoustat 2•2s after owning them for years and not having blown them. The result was improved transparency.
I wouldn’t be concerned, however, with mismatched values so long as they are at least as much as stock.

This is an interesting question as most of the ESS speakers in my collection have some sort of fuse protection. Several have circuit breakers. I have never tried to run the speakers by bypassing the fuse protection. I have also never tried to test the sound by temporairily putting higher amperage fuses in to see if it made a sonic difference.
Fuses and circuit breakers certainly add connecting points for the signal to have to pass through. So could there be signal degradation? Anything is possible.
However, on several occasions I was very happy to have the circuit breakers on the AMT 1a speakers as they tripped and saved the speakers when an errant family member tried to operate my rig when I was out of town.

Yes JCIDAVE you have hit it out of the park! Like you I have speakers with tweet fuses . Kef 104ab and those fuses were not installed on the 104 models .Since I had bought a pair of the 104 first I knew nothing about clipping and burned out 3 tweets before the stereo shop whom I bought them from replaced them under warranty . They had a fit and demanded to know how loud I was playing my music. Half volume . Too loud for a 58 watt amp I was told. Long story short they told me to buy a more powerful amp and they would install a 104ab twee set up in each cabinet free. So I purchased the SX950 pioneer amp and have burned out many half watt fuses since . Like you so have family members. My advice is who ever designed your speakers or mine took into account any variations the fuse may have made and accounted for it in their design . Ledbailey

I would agree with your dealer that if your volume control is at 12 o'clock with a 58 watt amp, you are pushing it past clipping on loud passages. Next question. How do you set your tone controls? Are they flat or do you boost? Do you use your loudness control?
Where do you set the volume control on the 950 when it blows fuses? How do you set those tone controls? The 950 is a very nice receiver but at 85 watts, it is not even 3db greater in headroom from the 58 watt amp.
My abusive family member lives elsewhere. I don't blow fuses or circuit breakers anymore.

Hi Dave. Thanks for your interest on this topic. So let me break this down l bought a Technics 58 watt amp first and had the burned tweet problem at just under half volume on the 104s. so to combat that I purchased the SX950 and the 104Ab crossovers with the .5 amp fuse holders were installed. I set the SX up with treble on two thirds... base half and loudness toggle on for extra grunt. Volume can be from low to just less than half but never half depending on music and mood. I also have inline fuses. I installed 1.5 amp when the speakers got older and I did not think I could purchase replacement parts. Its rare now to blow a fuse . Could be my age but let me know if you have any other questions. Soon I will be stacking the 104abs with my Visonik/David 502s on top .Ledbailey

I think it was wise of you to install in line fuses especially if replacement parts are scarce. I was going to suggest that. I think the fuse amp rating is a good choice. You are doing some boosting, which uses up amp headroom and can drive into clipping early. Good you are not blowing many fuses anymore.
If you will play your stack of speakers together at loud volume, the Pioneer may be out of gas. I suggest a separate larger amp and use the Pioneer pre out feature to drive the Pioneer amp and new amp.

Loudness always ON
Fuse is in the ears of the beholder of... the volume knob.

I like all these ideas. First the constant ringing in my ears must be over come by loud volume lol ?? Next if I hear the ringing not Queen I have blown fuses. Soooo the inline fuses were installed to protect the 8 inch base and the passive radiators so playing the stacked Visonik/Kef combo I need only to pay attention to the flashing lights on the 502s that indicate ....THE RINGING WILL RETURN DUMMY!!

Dave. I have considered an extension amp but do not have knowledge in what type of set up would be best suited. My listening space is around 14x14 ft. I love the 950 as it has many plugin options . Also I would like to stay vintage and true to late 70s gear. I am a paid member but have not received an answer back from AK as to weather BT is still listing. Any help you may offer is well appreciated . Ledbailey

Just an old fart trying to help.
Usually fuses are used to protect only the tweeters.

Everything affects the sound. Once that's understood it's a matter of how much or in what way and does it matter, that's where it gets interesting. Thing is if you can hear it then it affects the sound.
