Bad news for the IA80.1
2 pointsBut, but, but, it didn't do rated. It has to be flawed.... I understand their view, and their concern is not legitimate in this case, in my opinion. The results may not be 100% precise, but they're accurate enough for the purpose they serve. If you require an amp test to be accurate within 10 watts for your personal use.... so be it. I don't. You're the only one name calling here... So you think it's just barely off? For one, the testing method is not consistent. Like others have stated before, it's used for TROUBLESHOOTING, not for proper power measurement. Second, did you know it was recently retested by the same person and now it's went fro 13.5 to 14.6v and gained 3,200w? Now it's over 10k clipped. People are "guessing" in that topic as to how much THD that is.. Bam- guessing.. that method of measuring power is for troubleshooting. For accurate results, testing must be consistent. The 2 tests are not consistent and not controlled due to human error and the lack of THD measurement. You can't state you obtained a certain amount of power without other factors. Tfade has not done anything wrong to defer his measurements. It's the lack of knowledge the audience has that concludes what they think they obtained from that information. The same thing goes for many SMD devices as well but don't get me started on that. So the measurements show a lack of output power.. Well.. that's not right.. Test again.. now we have massively increased power... Lack of consistency and other measurements. Tfade isn't trying to replace proper means of measuring with a low cost technique. He's basically just trying to see if the equipment holds true to it's ratings. The problem is messing with amps of this caliber is not easy because the higher the numbers go, the greater the inconsistency in his testing method. The audience should take THAT as a big potential problem that is hard to control. Even on low power, his method will net him closer to actual ratings but still not concrete enough because of a lack of tools and technique. A power rating consists of a lot more than just 1 power rating with a voltage and a THD rating and not even those 3 things have been met in sync in one test yet. Like i've said many times before, I defer to the manufacturer's testing themselves as they are more equipped for the task.2 points

Bad news for the IA80.1
2 pointsReread the thread. 95Honda and M5 both posted reasons why. No one supporting the test even responded to those posts with a meaningful reply. And frankly we've discussed clamp tests on this forum a couple dozen times. Last I checked the search function worked fine.... And if you were paying attention, you would have understood this was M5's point. The READER shouldn't HAVE to ask. A valid test conducted in a meaningful and useful manor would have that information presented as part of the details of the test. The very fact we would NEED to ask in itself supports the test's lack of credibility and the fact the tester either isn't aware of these factors or doesn't know how to calculate them, or more likely both. But because he's posted numbers, the internet assumes it's valid and meaningful and it's everyone else's job to prove why this isn't the case. That is exactly ass backwards of how science and metrology actually works in the "real world". The onus is on the tester to prove it's validity, not the other way around. And he hasn't done that, nor have you or anyone else supporting the test....but that doesn't keep the lemmings from jumping on board with it. Though you blissfully skipped over 95Hondas post where he stated he's had Fluke meter with a 25% variance while ranting about nobody citing examples of why the test is flawed. Selective memory? Because they like to believe "numbers" regardless of whether or not those numbers actually mean anything, but don't want to put forth the effort into considering why those numbers don't mean anything. They prefer subjectivity and "experience" over true objectivity......because that's all I see when I visit other forums. Threads like this and that thread on CACO are prime examples of that.2 points

Though you blissfully skipped over 95Hondas post where he stated he's had Fluke meter with a 25% variance while ranting about nobody citing examples of why the test is flawed. Selective memory? Don't you find the statement about one fluke meter being around 25% off from the actual results rather anecdotal? I've never heard of that issue being had elsewhere.And don't you find the fact we know nothing about the accuracy of the equipment used a little troubling before trusting the results? Obviously not, and that's the problem. You promote the results and how useful they are when you or anybody else knows nothing about them. You claim they are "close enough to count".....but the fact is you don't know, nor does anybody else. And that's one of the problems. Especially when people are using this test of unknown credibility and comparing it to manufacturer's rated power which is a specific measurement, and then making a determination of the amplifier based on that test. Think about it for just a second. Ask yourself why actual amplifier designers and manufacturer's and other's in the audio electronics industry spend tens of thousands of dollars on test equipment if a kid in a basement is capable of duplicating the results for a few hundred dollars? I don't think it's because these multi-million or billion dollar companies are that gullible, but I certain would think it's because the engineers understand proper testing methodology and what is necessary to achieve meaningful, repeatable results. Just because he can post some numbers doesn't mean they are useful, "real world" or "close enough to count".1 point

1 pointGoing through I don't think they meant you were bashing the company/nick but others. I don't see how they're being sarcastic. Impious, tirefryr and shizzzon were trying to explain. M5 was the only one being sarcastic and was only doing it because tenacious is annoying and ignorant. I don't understand why you guys don't listen to these guys... Zero tact and constantly talking in circles rather than being direct. Discredits whatever they see fit without truly explaining why everyone else should discredit. They act as though they're %100 right, but fail to fully disclose why they are correct and someone else is incorrect. They scream tolerances and calibrations yet never give any real numbers. They never ask what the given tools tolerances are and if they have been calibrated or when the last time they were calibrated. Just because you have technical training behind you and some real world exercise, doesn't mean you have the right to discredit everyone else. It's easy to sit behind a computer and seem all so intelligent. There's a common factor of why a lot of people don't like this forum. Maybe you should go and seek some education and then you might understand just how much money, time, equipment, etc... goes into testing, measuring, certifying etc. Right now it seems that all these guys are "talking circles rather then being direct" but you clearly do not understand this subject. Once you go out and find the necessary knowledge, then you will realize how right these few guys are. Until then, argue on and have fun!!1 point

1 pointBlind leading the blind.His equipment isn't calibrated.....so how do you know it's only off .01V That's one of the points....you don't. I don't. He doesn't. Therefore we can't call the test accurate. Because we don't know. And that's just one of the many reasons.1 point

1 pointBut, but, but, it didn't do rated. It has to be flawed.... No one here arguing against clamp tests gives two shits what the "test" showed for power compared to rated. Why? Because the test isn't a valid test to start with, so no matter what the results should be discarded. We've always stated the same thing regardless of manufacturer, regardless of who did the test, regardless of what the claimed results were.Props to Taylor for trying. But trying hard doesn't make the results any more meaningful. I don't care if the amp is in fact over rated. Just prove it with a valid test.1 point

-1 pointsTake into consideration that this is a fixed resistance test. Voltage and amperage are not out of phase as they are in a standard clamp test. This is about as close to "real world" numbers as it gets.-1 points

-1 pointsBut, but, but, it didn't do rated. It has to be flawed.... But but but.. the owner said he will retest because all testing prior to marketing is correct and will retest.. However once he said that.. many people started bashing the "potential" for his other products to be flawed, etc.. I only trust the owner and\or companies who do this for a living. If one person can be trusted to "fail" an amp publicly, then all companies might as well shut their businesses down because you know what they say.. The customer is always right... So professional testing must be pointless.. We don't care about getting close We, as a business community, care about doing it right. Why would a business rely on a customer's test as the official ruling of their products potential. That is the dumbest thing i've seen this year so far and that's pretty damn bad. But keep supporting the "close testing". We'll support professional test results. I'm fairly sure you can consider Taylor's tests "professional." Your average consumer doesn't have a bank of fixed resistance and all of the equipment to properly test amplifiers like he does,-1 points

Maybe you guys forget what they've done for me. I haven't. No one has answered my questions yet but I knew that would happen. It's always a dick measuring contest. Who can be the better sarcastic prick! Soup sandwich.-1 points

-2 pointsNick is doing it because people like the OP, yourself, and MR. Tenacious just do NOT understand what is going on here. You think you do, and no matter what more intelligent people tell you or point out, you continue to think you grasp what is happening. Therefore, his company's reputation is unjustly soiled due to people who know enough to cause damage and nothing else. Don't get too cocky.-2 points
