Hey guys! Cross posting here for people who aren't subscribed to the Tanchjim thread.
I received
Tanchjim Prism this week and finally got to spend some good time with it today to jot down my OOTB first impressions. If you haven’t come across it yet, Prism is Tanchjim's new
1DD+2BA $599 flagship. It has a
4th generation DMT dynamic driver with high polymer carbon nanotube diaphragm and a Sonion dual balanced armature driver. It has a
Vibration Suppression Metamaterial Back Cavity design which is based on the Helmholtz resonant cavity principle. What it basically does is absorb the reflections inside the cavity so that the transmitted sound is pure and natural. They’ve also designed a
guided leakage channel port specifically to match the back cavity, which as per Tanchjim helps in managing the sound pressure in the inner cavity and optimises it by appropriately increasing the atmosphere flux.
Fit wise, it fits me much better than Oxygen and I get a nice, fairly snug and comfortable fit with the Large size stock ear tips. Sound wise, I have to say that I’m quite impressed, especially with what Tanchjim has achieved with just 1DD and 2BAs. The first thing that impressed me right off the bat was how open, clean, wide and deep its soundstage sounds. A lot of good IEMs are able to do width fairly well but not depth as nicely. I don't say this lightly but Prism does both in an interesting manner which enables a fairly holographic listening experience, not something I've experienced a lot with IEMs in this price range. Tuning wise, Prism traces the Harman 2019 Target curve till 5kHz extremely closely, if not perfectly, but deviates from it in the treble region. Prism has a nice Harman style 7-8dB bass boost; very good bass timbre, punch, impact as well as rumble. Prism has a fairly linear and neutral lower-midrange, forward upper-midrange with around 10dB pinna gain, nice and smooth lower-treble tuning and a very nice tasteful north of neutral upper-treble boost, which is responsible for its open and airy signature. Tonality wise, I find Prism sounding natural, well balanced as well as exciting, all at the same time. It has really good technical capability too, especially spatial imaging and separation. It comes with 2 sets of ear tips - Treble and Bass. They sound close but I personally prefer the Treble ones, though I don’t really perceive them sounding much brighter than the Bass tips.
Kindly note that these are my first impressions and my opinion might change over time as I take Prism through its paces with extensive testing and comparisons with other IEMs in my collection. With that said, I doubt they'll change that drastically. Anyway, I'll let you all know if I have something substantial to report. Otherwise, keep an eye out for the full review, to be published soon on Twister6 and Head-fi!
