I'm in the same boat and like them analytical but fun at the same time. But we can't have our cake and eat it too I guess.
Well, out of the 3 IEMs in my collection, I guess the ZAX would fit that bill. They are SUPER fun sounding and have great detail as well. I've been kind of neglecting them ever since I got the Dusk and P1, but revisited them last night and man they are special to my ears (especially when running balanced with the DUW-02 cable). Honestly, the ZAX has been the most impressive out of the 3, especially given the price point. I would say their main strengths is their expansive soundstage (almost open-back headphone like) and layering capability. They can make badly recorded mainstream pop songs sound really good. The sound signature is U-shaped but not in a bad way. Vocals sound clear, perhaps slightly recessed, but with great detail. Otherwise, pretty balanced sounding. I think they do vocals better than the N6P (which were my favorite for TWS). Listening to Billie Eilish for example, sounded great on the Dusk and P1, but they sounded amazing on the ZAX with the much wider soundstage and layering. Bass is tight with good punch (maybe lacking definition), and treble is just enough where there's good detail without any harshness (there is a slight roll off at the upper treble though). They're a really versatile jack-of-all-trades type IEM. Also, depending on the source, I was running Tidal from my PC to the Hip Dac (versus using my phone), I swore some recordings sounded like I was listening to a HD audio cassette tape. Super smooth and analog sounding.
The P1's sound pretty close to the Sundara when driven out of the Hip Dac. Tuning is similar where I think there is more emphasis on mids/treble and more on the lean side. Although, I have a feeling I haven't unlocked their full potential, and will sound much different when driven by a proper desktop amp. I actually find the soundstage on the P1 to be pretty good. Still "in your head" feeling but very wide and airy compared to other IEMs/TWS.
I've been hesitant to give my impressions of the Dusk since I feel like I haven't spent enough time with them yet. My first impressions were unremarkable. They sound very good, but I think because of all the hype, I had really high expectations for them. Tonality wise, I think they are near perfect. I guess they somewhat remind me of the HD650 having a "darker" type of sound. But their biggest weakness to me is their soundstage and treble roll off. Soundstage is slightly above average at best. They sound really good, but when there are busy passages, it can get quite congested. For Vocals, I'd give them the slight edge over the P1 and the ZAX. But for acoustic guitar, they would be dead last (behind the Tevi, GT220, CX400 as well) due to the treble roll off. I actually went back to the stock tips for these. For some reason, the small tips made the soundstage even worse and narrow. The Spinfit CP155 did help with soundstage, but made the overall sound slightly leaner (may not be a bad thing). I eventually settled with medium stock tips and they sound just right.
Dunu EST112 on the way...these are gonna be the "endgame" IEMs for me (and the last purchase of the year
). I've actually been eyeing the Clairvoyance as I wanted to try an "electrostatic" IEM. But after hearing news about the EST112, seeing its FR graph, and positive early impressions, these were pretty much a must buy.
