    Even though I've had the DP-x1 over 6 months I haven't gotten to the point of testing out the different filters or "lock range adjust" so I've just been using the default SHARP filter on low gain this whole time. Honestly I am not entirely sure what these digital filters even do. What are your thoughts with Jupiter and the filters? (If you've messed around with them I'd love impressions on the filters, maybe in the DP-x1 thread?)

    I'm still waiting for my Campfire IEMs to come back from my personal loaner. I'll definitely report back but currently I feel the SHARP filter might be fucking things up. Need the Andros to be sure.

    hi

    In terms of musicality (as well as ambience retrieval) does the existence of Lyra2 and Dorado render Jupiter less competitive or does it offer enough unique attributes to stand on its own against the two newcomers?

    thanks in advance

    I will attempt to answer this (wrt the Lyra2) in a moment. Sit tight.

    Musicality is a loose term that could mean different things to different people. You will have to be more precise.

    Neither Lyra 2 or Dorado render the Jupiter less competitive. Andromeda, Jupiter, Lyra 2, and Dorado all stand on their own. I consider the Andromeda the reference: the most resolving and the most neutral, with the Jupiter being a more relaxed presentation take of the Andromeda. The Lyra in comparison to the Andromeda is more organic and bassier with maybe a slight mid dip. Its less resolving, has more natural timbre, and slower, but still faster than other DDs on the market with the exception of the Vega. The Dorado is like a Lyra on the low end and somewhere between Jupiter / Andromeda on the high end.

    Yes it was a wee imprecise, my apologies, i suppose musicality as in articulation.

    Nonetheless, thank you for the very informative impressions on their differences!

    The BAs win in terms of bass, mid, and treble articulation. That would be Andromeda and Jupiter, with Andromeda having a very slight lead.

    Judging from descriptions, I think I'd like the Jupiter or the Dorado the most. I'm admittedly a bit worried about the Andromeda and Vega's treble.

    I got a pair of Orions as a gift, and I find them decent but a wee bit fatiguing.

    Revisiting this thread, I would be interested to see a plot of the Andromeda vs Jupiter with the bass levels matched on the vertical axis (as opposed to matched at 1k). I think the difference in mid tone would be more visible.

    I have the Jupiter in hand right now and I am struck by how vibrant and clear its midrange rendition is. I think this is what had really sucked me into listening when I first demo'd these 3 years ago. Although I only had a brief demo with the Andromeda, I do not recall it having the same succulent midrange quality.

    From memory, I do not recall the Andromeda's being significantly brighter in the treble than the Jupiters, but I do recall that difference in mid tone.

    I got this one. First overlay is matched at 0dB (I think it was 100dB SPL?), second is matched by eye at 100Hz. Red and green is Jupiter, cyan and magenta is Andromeda:

    EDIT: removed matched at SPL because they were about exactly even at 1kHz anyway.

    I've not gotten ears on the Jupiter yet but have had some meet and store condition ear time with Andros and Solarises. Andros are definitely somewhat bright to my ears but far from offensive as some think [coupler artefacts FTW], I actually don't see the downward slope and rounded blip at around 2kHz as bad, but then again it's similar to how my main headphones nowadays are, haha. Good sense of "fake" depth and all that, some extra edge to upper harmonics of vocals :p

    Thank you @Lyer25 !

    That sorta confirms my original suspicion. The two IEMs are quite similar in overall tone, but have a polar opposite takes when it comes to the upper midrange response. I think that plot makes it easier to visualize.

    I used to take graphs aligned at 1kHz at face value too, but a few months back I figured it isn't really reflective of use case a lot of the time especially for less normal cans like mine, lol. Have been snipping measurements from here, Chang, Soundstage, DIYAH, InnerFidelity etc. for a while and actually align at closer to 600Hz or so when I'm curious to compare FR. Definitely agree it's easier to see differences in midrange that way.

    Different distortion characteristics. Will let you guys guess which is which based on @OJneg's description of Jupiter's wonderous mids.

    YELLOW = H2
    GREY = H3
    VIOLET = H4

    I've been meaning to ask, @purr1n. Is it more acceptable for D3 spikes to manifest in IEM measurements because those are more coupler-fault than the fault of transducers or something? You've mentioned several IEMs such as the EDC3 which have impressive (not in a good way) amounts of 3rd order well into upper midrange sounding pretty well-controlled etc. I don't think it's any sort of cheap or easy to simulate ear canal performances, ergo the ridiculous GRAS gear pricing.

    And yup, I caught your notes on how D2 in IEM measurements have low validity, but this is D3 surpassing so not sure if that falls under the scope of your statement.

    BTW I cheated by peeking so spoiler-ing answer :))
    Jupiter top, Andro bottom?
