Okay in a single paragraph, give me the bottom line why the Bathys is a better headphone than the Px8. I will throw aside all my notions and genuinely listen. Explain it to me please.
More correct is saying: "give me the bottom line why the Bathys
[for you] is a better headphone than the Px8." I try answering because you saying "I will throw aside all my notions and genuinely listen. Explain it to me please." I think part in you is genuinely asking (or is genuinely curious) even when at the end I think you still thinking the exactly same thing than before. But I try...
In one short sentence: Better sound, better construction, better transparency, BETTER playback buttons, and I prefer the design even when isn't exactly really my style (b&o designs are really many more my preference, big difference here).
One paragraph? Sorry but I using more than one because is more easy for reading (think like is one little more long paragraph).
Independent of the FR graphs (we don't have 'official' graph for PX8 yet, by the way) the Bathys is making instruments more separated but not far away from each other. mainguy is often using the word "holographic" in his comments/comparisons. For me isn't exactly this word, and isn't either the word "surround sound" either, but a more spacious head-stage, more natural comparing with how we hear instruments together in real life, with instruments having more space for breathing but still blending and not so together like in PX8, a sound that is very good (of PX8), but little congested sometimes and always 'in your head', a little more 2-D, specially in more busy passages.
About the frequencies, like the p7w, the px8 is missing sub-bass presence and some sparkle in more high frequencies (maybe the p7w is actually having little better treble in general), but the midrange in px8 is very, very nice in general, and even when bass is affecting mids a little, the mids is still very, very attractive. With Bathys I want just little more mids presence but I'm accepting the compromise for the general presentation. The sound, in general, of Bathys is sounding little more clean too, but not clinically/sterile clean, just with little less distortion.
When using EQ, both headphones, FOR ME, are improving but the PX8 EQ isn't giving me the options I really want (I'm not sure more low bass is possible even with EQ here). The bathys EQ isn't giving me ALL the options I want either, but is giving me better options.
Speaking in emotional aspect, something completely very personal, of course, I'm connecting with music more with Bathys than PX8, is almost like opening window and permitting some fresh air coming in. The Bathys are showing me majority of music in a very, very attractive way usually. The pX8, similar like p7w, sometimes is making me say "play next track, please, something isn't making me connect"
