For quite a few of my head gear devices, I totally agree with you, so you have at least one in your corner...
Well said sir!
I don't believe the correct term for the DX320 is better anyhow IMO. As mentioned earlier, I believe that we have pretty much reached a plateau where if there IS room for improvement in sound quality, diminishing returns makes you need to be OCD (a bit) to feel the NEED to upgrade if you already have and enjoy your DX300. That leaves out those that just love getting new toys and such, and I am certainly not accusing anyone of having mental issues if they want to get the DX320 after owning the DX300...
Bottom line is that, while tempted with the DX320 (because it WOULD be a new toy to play with), I am more than happy with the DX300, and I have still not even had my amp12 card modded, nor heard amp13 yet... That ability to change the sound of this thing with the removal of two screws makes it new and refreshed any time I want. In my mind, what more could you want? Oh, and there is a little thing out there that can help you tweak the sound to the way you like it should it be JUST a tad off, and it doesn't cost $1500 to $2000 to get. It is called EQ...
After all we are talking about buying new hardware to tweak the sound to our tastes, because if a DAP is neutral and the technicalities are all there (faithfully reproducing the sound), I really don't see how it can get better. At that point, you are either happy with the sound or not, and if you are not, then you are looking for coloring in the sound, in which case the EQ fills that bill (or even changing head gear also).
So, really in my mind what makes a DAP TOTL flagship is really all about the technicalities, in which case the DX300 would be the best of the best (they had some firsts with a portable DAP, and the specs are outstanding; SNR, THD, etc...). It then comes down to how they tweaked the sound. Well, I can tell you they all sound different. Does that make them better? Only if your ears say so. Just my thoughts..
Having said all of that,
@RIGATIO is a pretty good salesman, though I would say far from non-biased in his thoughts (he is all in or not at all)....
I may have to give those darned pieces of crap he's been going on about for a while now a try..
Though, I still think my next one will be the Hook-X, and amp13 first.
again!
