uberwaltz, thank you, I hear you. I made the visit as early as possible tomorrow. Dalton was only 7 months old. Made a gallant effort at making it. Nuff said.
Something For The Fuse Guys ...
There are fuses, and then, there are fuses.
I'm evaluating some prototype fuses that I received in the mail three days ago.
Over the past few years, I've used fuses from five different manufacturers. The last three were the Red, Black and Blue fuses from Synergistic Research. Each one incrementally improved the sound of my system. My favorite so far was the SR Blue.
The prototype fuses being evaluated presently raises the SQ beyond all of the others mentioned above. The major improvement to my ears is better tonal accuracy. Instruments and voices are more life-like. The noise is reduced allowing for a more solid 3-D presentation with the musicians more solidly presented on the sound stage. Overall, more information is fleshed out of CDs and LPs.
The manufacturer, the price and the name of the prototype fuses will come later. I don't have the information thus far. My understanding is, if all works out, the release date is to be mid-October.
Stay tuned ...

Talking about fuse directionality, Hifi Tuning has a logo with a diode symbol in it. At some point people began believing this diode-arrow was the factory tested recommended direction of the fuse. But it was not, it is just a logo. Personally I do hear a difference in a direction, but I also believe it diminishes after some power on. |
HiFi Tuning started off claiming that fuses break in correctly no matter which way they were first inserted. But later, about the time they had an independent testing company look into directionality of fuses, they changed their tune, as it were, after the results of the testing, including listening tests, was completed.The results of the tests appear on the HiFi Tuning website as the so called Data Sheets, which shows measurements of voltage drop across various fuses, both directions, including HiFi Tuning fuses, with and without Fuses were tested in both DC and AC circuits. http://www.hifi-tuning.com/pdf/wlfr.eng.pdf |
The GECOM technologies document is not a proper report of a metrology testing lab, this is purely a marketing document and an auspicious one at that. Let's point out the BS in the document: 1) No listing of equipment is provided, no pictures of test setups, nothing. Just take our word for it on the testing. You and I know, that is not how testing labs operate. Every test has a full equipment list and normally pictures. 2) The resistance difference "claimed" from direction 1 to direction 2 is on the order of 0.0001 to 0.00005 ohms, and the claim in some cases represents 0.05% difference at 2-3 milliohms. Check out their accuracy page. They can't even measure to that accuracy at those resistances .... and they are claiming to be able to repeat it in both directions? 3) Copper resistance has a temp coefficient of ~ (3.8* 10^-3)/C, silver similar at room temp. That means a change of 0.38% in resistance value per degree C ... and yet they claim in their report to measure resistance changes to an accuracy of 0.05 - 0.1% or the change that would occur with a 0.25 celsius temp difference. I am calling BS .. super big time BS. There is 0 chance they temp controlled in that lab (see pictures - not a proper metrology lab) to that accuracy, AND they would need to use pulse measurements to eliminate self-heating (no mention), which means on time would have huge impact due to self-heating of the fuse temperature. (p.s. also means that the temperature of your wires in your audio system has way more system impact) 4) They talk about Vector Impedance measurements, but don't claim the HiFi is the best for those (like every other one) ... and curiously the mentioned table of results is missing. 5) Their "noise increase" is not nearly well defined enough to be meaningful. Increase over what as a start. OH, and this is the best one. You can guarantee every piece of equipment they use has a garden variety fuse in it, is powered with a cheap power cord, and is connected to a rather garden variety power bar. But sure george, you use these worthless results to try to justify your position. geoffkait17,710 posts10-25-2019 5:48am http://www.hifi-tuning.com/pdf/wlfr.eng.pdf |
