I am saying anyone's interpretation of such a petty and subjective thing as "percentage improvement" is pointless, including my own, which I provided as an example to illustrate how futile it is. It's also worth clarifying the distinction between "percentage of the overall sound" and "percentage difference between two things"... For example, someone could say component B is "25% better" than component A, but clarify that this particular type of non-transducer component only accounts for perhaps 5% of the overall sound. Differences in sound quality and sound signature are also highly relevant. What I was referring to was overall sound quality. Obviously, sound signatures can differ drastically. Again, your 200% could be my 5% even if we're hearing the same thing. The way I hear it, the last 10% of sound quality is what accounts for the things we audiophiles appreciate. Yes, it's better in an obvious way, but not that much better, really. Most of the sound is already there with some of the better budget headphones. Not everyone has sufficient experience in that area, so it's not surprising that some assume all headphones under $XX suck, which is, in fact, not the case. I said "90% as good as any headphone I've heard"; I have not heard them all, and I have only scratched the surface of auxiliary components. To be fair, these impressions of mine are primarily based on driving it from the Chord Mojo. With cheaper electronics, it, unsurprisingly, didn't sound as good. So if it makes you feel better, you can increase the price of that 90% as good thing to over $500. (Though I'd still place it around the same number with a sub-$100 DAC/amp.) Personally, I ultimately don't care what something costs; I only care about the sound and the experience it gives me. If I'm not satisfied with what I got, I'll move on to something else sooner or later. Since I want to eventually attain the highest fidelity system(s) I can, it's also inevitable that I would move on even when I do greatly enjoy something. I did not intend to refute anyone's claims, and I do respect and appreciate others' impressions and opinions. I just wanted to take things back down to Earth, so to speak. It's easy to get excited about things we enjoy and exaggerate how much of a difference there actually is between them. I hope I got my point across, because I'm not fogging up the thread further with this topic. Back to Diana!
