If I were you, I wouldn't repeat these claims to a group, as there might be someone like me that knows what a filesystem is, how it works, how decompression works etc. etc., as he might have been doing this for work for many years, even while writing these sentences.
Anyway, I am out of this discussion. I was mainly following to find out if someone is using Wavelet or Poweramp EQ with DX320, as my question was not answered before. I guess I need to buy and try myself.
Enjoy the DX320.
You see, I greatly respect your experience and knowledge! However, the tone is very off. If anything, it's threatening. Nobody here is above anyone else. We are all equal =)
Our experience, knowledge, etc. varies, but that doesn't mean that you have any right to tell someone to not share their observations. Our observations are relevant, your observations and knowledge is equally as relevant!
I know this is going to sound very wrong and I want to let you know that I don't have the intention to humiliate you. When it comes to technical knowledge, there are levels to it. This conversation would be much easier if we had these differences on paper, because then you would focus on finding out the answer to "Why is this happening?". It's not uncommon to see someone with a certain level of knowledge/experience unable to understand something that is beyond their knowledge/experience. This is not a personal jab at you, I'm just saying that there are probably levels to it. Being just a casual listener with no technical knowledge, I don't know what level you are at and whether you are a qualified expert to make speculations as to why we might be noticing a sonic difference with microSD cards.
The whole point of a website like Head-Fi is that there are thousands of us sharing our opinion. I can't speak for others, but I know for a fact that my intentions aren't to convince others of anything. I'm just sharing my observations and that's about it.
There are many, many, many... unexplained things in this hobby. I am not trying to make you admit that we are right, but I also think it's not okay that just due to your experience our experience should be dismissed. According to your knowledge due to years of working in that field, what we have heard should be impossible or an indicator of bad design, right? But at the end of the day, we heard those differences with our ears.
As to why microSD cards make a sonic difference, that I cannot tell you. Did I hear a clear difference? Yes. Was it only once? No.
It's a very controversial topic and you must stay open-minded if you want to have a discussion. Usually these conversations turn into "my opinion is more valid than yours because of X" and get into heated arguments quite quickly.
If you were to do an A/B test with the approach that it's impossible that it can alter the sound, it would be of no use. However, if you approach it neutrally and you find a difference and say "Hey, I'm wrong" that's the way to do it. The next step is to answer the "Why?". That's how you go forward.
It's like when you are employed, you leave all your problems at home and act professionally at work. When it comes to A/B tests, leave the judgement and prejudice behind you. Because, if you are entering an A/B test
to prove your point, that's bias. However, if you are entering an A/B test to make non-biased observations, that's something different. Can we agree there?
Once again, I don't know for others, by I'm always trying to find out whether something is real and if so, why is it real. I would be more than happy to be proved wrong with science, I have no ego when it comes to that. I can say "I am wrong" and the next step is to try to understand as to why I was wrong.
In science, you have outliers and things that behave out of the norm all the time. A scientist isn't going to dismiss those outliers and unusual behavior, instead he is going to try to understand it and find out why it is that happening. Think outside of the box =) The box is the known, everything outside of that box is the unknown.
I know it's getting kind of off-topic (though it's still relevant because we are talking something that was noticed on the DX300), but I just want you to know that I'm not here to dismiss what you have to say.
