Rhapsodio Infinity Mk2
Following on from my Supreme Mk2 impressions I shared a few days ago, I think it's time to share some thoughts on Rhapsodio's other flagship IEM, Infinity Mk2. I want to thank
@hshock76 once again for generously allowing me to demo both Infinity Mk2 and Supreme Mk2 for the past few weeks.
Infinity Mk2 is a 6 balanced armature driver IEM with exclusive "Dual Copper Coil" technology that retails for USD $3,600, placing it in a very competitive flagship price bracket that includes heavyweights like Empire Ears Odin and 64 Audio Tia Fourte. The two copper coils house what appears to be 4 of the 6 BA drivers and look to be connected to the crossover circuit board. What exactly these coils are doing to the sound is unclear to me, but they do look cool
Sammy certainly knows how to create a distinct and striking looking IEM.
However, the coils are quite large and as a result, Infinity Mk2's acrylic shells are
massive. In fact, I think it's the largest IEM I've ever used, even surpassing the Sony IER-Z1R and Campfire Audio Solaris. This caused me a bit of trouble achieving a decent fit, and unfortunately, a deep insertion seems to be crucial for Infinity Mk2 to sound right. Without the right fit, I noticed that bass thins out severely, and the upper mids become too shouty and piercing. I rolled through my entire collection of ear tips, and settled on the SpinFit CP145 in medium size. I also had to swap to an Effect Audio Ares II+ cable, as the stock Rhapsodio cable's ear hooks simply would not work with the shape of my ears and how far the Infinity Mk2 protrudes from my ear canal.
Another important thing to note is that Infinity Mk2 is highly source sensitive. Switching between DAPs will offer a drastically different listening experience. I'd be interested to see an impedance curve measurement as it appears that a lower OI brings out more bass, not too dissimilar to the Campfire Andromeda. It also hisses like an Andromeda, so a low noise floor DAP or source would be required if you want a silent background. I tested Infinity Mk2 on all my DAPs and found the iBasso DX300 (with Amp11 mk1) to pair best to my preferences. I did notice a small amount of hiss, but it didn't bother me too much and was hardly noticeable while music is playing.
Infinity Mk2’s tuning is what I would describe as a treble leaning v-shape, with a prominent upper mid, lower and mid treble emphasis, countered with a recession from mid bass through to the lower midrange. This tuning gives Infinity Mk2 an exciting, energetic signature that works especially well for music with female vocals and string instruments. However, the tuning may not work for everyone, especially bassheads or anyone sensitive to forward upper mids and treble.
Bass:
I would consider Infinity Mk2's bass to be neutrally tuned, with what appears to be a
slight sub bass boost that slopes down through the mid and upper bass frequencies. As i mentioned above, bassheads will want to look elsewhere, especially if you need a solid mid bass slam. Bass transients are fast, with typical BA texturing and decay. Overall, the bass does a decent enough job to support the mids and treble, but it certainly isn't going to be the star of the Infinity Mk2 show. I personally find the bass to be it's most disappointing feature. I definitely would've preferred more mid and upper bass to make it a bit punchier and warmer.
Mids:
The midrange follows a typical V-shape tuning, with lower mids being slightly recessed compared to the upper mids. This tuning creates a revealing midrange that does an excellent job at presenting detail and nuance for both vocalists and mid instruments. Strings sound particularly crisp and bitey, allowing each pluck and strum to be clearly rendered. Vocalists, especially female, are presented quite forward, and the upper midrange emphasis allows vocal harmonics and overtones to shine through, giving the vocals an airy and clear timbre with ample body, but can potentially sound a little harsh depending on your tolerances.
Treble:
Infinity Mk2 has a vibrant and highly energetic treble response with excellent upper treble extension. Cymbals and percussive instrument decay sounds shimmery without sounding harsh, sibilant or overly strident to my ears, Overall, I find Infinity Mk2’s treble very enjoyable that will probably suit trebleheads, however the sheer amount of treble, coupled with the forward upper mids may be an issue for sensitive ears or those that listen at higher volumes.
Technicalities:
This is where Infinity Mk2 really excels, and why I personally would choose Infinity Mk2 over Supreme Mk2. Transient speed across the spectrum is incredibly fast, imaging is super precise, and the soundstage is one of the largest I’ve heard in an IEM with amazing width and depth. Instrument separation is also top notch. At no point through my demo did I feel any sense of congestion or congealing of notes. Detail retrieval is excellent, up there with the more detailed IEM’s ive heard like Anole VX, Odin and Traillii.
If you are a sucker for technicalities like I am, then I highly doubt you will be disappointed in Infinity Mk2’s technical performance.
Conclusion:
Infinity Mk2 is a fantastic, extremely technical IEM with a highly energetic and vivid sound. Once you get the right fit and use a complimentary dap/source, it offers a euphoric listening experience that will certainly satisfy the upper mid and treble heads of the IEM world. My main gripe is the bass, which to my ears, is a typical run of the mill BA driven bass response that lacks the punch and texture that I need for my music taste. I also wish the shells were a little smaller, and that it wasn’t so source sensitive.
