I think I heard a fake or broken IE8 in a store once, but I've had a lingering feeling it was real, it's annoying demoing high quality fake IEM's, or a fake ESW9 or whatever, fake Apple earbud, it just confuses perceptions lol.
I thought I heard a fake Shure SE210 too, since the other one sounded so different, it took me a while to figure out they were both real and Shure changed the driver at some point. The SE535 I'm not sure either, it sounded pretty good but the build quality of the SE425 felt slightly more substantial, hmm...
Most recently, there's been a lot of discussion on the Teclast T51, with conflicting impressions, it seems like it's most likely a fake opamp in some units, maybe the opamp supplier is cutting corners, who knows? All I'm saying is it's important to figure out why there are conflicting impressions, not just saying "this sucks" and "this is amazing" and then saying oh well some people like caviar some like candy.
The problem with head-fi is we keep theorising about candy and caviar we haven't tasted, and the packaging, price and popularity (three P's?) of the candy influences our take on it.
Yeah, some candy companies have a good track record, so when Auzentech releases a new cherry candy, people say "what..?" and ignore it, well that's fair, but all this has to be taken into account.
Now, not only can we not taste the candy, but the gear we use to taste it, the dac, amp, (/dap), music and equalizer, and if we just ate lemons or oranges for a month beforehand all influence the taste of it too, and that just turns these forums into an endless discourse of favoritism!
I'm not sure where I'm going with this, I just want to elucidate that there are potential objective ideals in audio where we could all hear music almost universally the same in theory, if you break down each component in the chain that has an affect on the overall experience.
To summarise, if you're in a room with someone listening to speakers, you're hearing the exact same music and sound, right? Or let's say, at a cinema watching a movie. You may have slightly differing views on the experience, but at least you're hearing the same sound.
I just wish portable audio discussed on the internet, was the same as listening to speakers in a room, I think that would make this more fun and more truthful.
So where am I going with this? I'm suggesting it would be fun to use the same DAC/Amp and listening to the same music (like somewhere online). Not all the time, just an interesting project on the side.
