What amplifier is that? Can you hear the changes? It's a Sony TA-A1ES. Together I put Audio Magic Ultimate Beeswax Fuses into it. So the combined results are huge improvement in low register. Much bigger, wider sound stage, tighter and more controlled base. The top end also improved, more delicate. Did you put the Audio Magic fuses internally ? as opposed to in the plug |

8 !
That must be the most for any hifi
A few bob on Audio Magic fuses too

Employing many fuses (assuming they assume you will throw away the stock fuses and put noise cancelling fuses into it once you got the amp) is the best way to isolate the noise and interference from components to components, at the heart of the current flow. |

At those costs I would have changed amps lol

The reason why there are so many fuses is because the amplifier is double insulated and doesn't have a protective ground. Safety reasons only. |

It makes it safe everywhere. How many countries do Sony sell equipment into? Just about everywhere is the answer, and everywhere doesn't necessarily have safety ground, and it isn't needed if you design your gear around that common denominator. Just about every volume electronics manufacturer does it.

Nice amp, I like the simplicity, clean lines and it looks well made internally.

Pretty much all of the Japanese electronica high end is double insulated even the TAD, and there front ends have pretty much the same amount of fuses, oddly enough I tried the AM BW fuses in those positions and it did not impact the sound, in other positions in different equipment systems then yes.
Now if I could obtain those TAD fuses (sand/material filled) in other values then life would be great.
However eight fuses plus donuts add up at this point would be looking at something else that is my personal opinion nothing more.
By Sony and Accuphase have they own sonic signatures, your preference is for Sony, others may like the Accuphase again systems and personal preference dependent.

Stand by for two Max Donuts to go into the Belles, Tony. They should arrive any day now. I've no idea what to expect but it'll be fun trying.

Hi Martin
I have a pretty good idea, I have finished off working on a same principle but more complete methodology of screening, and as there is space in the SA100 it will work as a full body enclosure of the TX's
The RF/EMI critical areas are much lower in the frequency ranges for toroidal tx's, the new emi software in the RTSA coupled with a multi domain (time and frequency) analysis helps pin point 'old skool' rough guesses rather well so a three pronged attack is required to fully deal with the radiated and conducted emissions. We can now interrogate the output and inputs form the TX's at board source, makes for quite a interesting study!

I never tried other similar tweaks wonder how BlackDiscus compared to others such as Bybee.
