I have reached a point where I am content with my two channel choices. But, in my never-ending quest to improve the overall sonic characteristics, I continually seek means to extract further improvements.
There has been a lot of talk lately regarding ‘Audio’ grade fuses and their contribution to the overall system characteristics. After researching and some enquiries, I decided to replace the stock fuses in my pre-amp and amp with HiFi-Tuning fuses. Two replacement fuses were ordered from Parts Connexion.
Once the fuses were received, I removed the externally accessible fuse from the Simaudio W-3 amplifier. The existing and new fuse ends as well as the external portion of the fuse holder were cleaned with Caig ProGold. The existing fuse was reinserted in the amp and a listening session was conducted. The new fuse was then inserted and the same selections were played.
I found the HiFi-Tuning fuse allowed the amp to create a more realistic representation of the source material. The presentation was more dynamic and allowed me to hear intricate details I was not aware of before. Acoustic instruments sounded more natural and occupied a more precise spatial location. Mainstream (electronic) material also benefited from these noted improvements.
I then removed the power supply component of the Simaudio P-5 pre-amp from the audio rack. The component was opened, the existing fuse was removed, the fuse holder was cleaned with Caig ProGold and the replacement fuse installed. The same selections previously used were once again played. The above noted improvements were even more pronounced.
I never would have thought replacing a fuse would add this level of refinement to a component. The collective refinements from replacing the two fuses add a new level of realism that is thoroughly enjoyable to listen to. Some may think the price for these replacement fuses is outrageous, but based on the obtained results, I can easily justify the cost and even think it may be a bargain compared to the overall cost of the system.
I am so impressed with the results I will be going through the remaining components to determine where a replacement fuse should be installed.
