If someone has the opportunity to check the Ranko RIE-1000, it is definitely worth it.
RIE-1000 is a model made by Tralucent Audio (company owned by Ranko Acoustics), but selling under the Ranko brand. It isn't the cheapest IEM, but for 470 USD it is one of more affordable true tubeless models. RIE-1000 has single dynamic driver and single balanced armature driver with RA|FPhase technology. In a box there is also RIE-Mini, a portable DAC/AMP (modified and upgraded version of Hilidac Atom with Lightning adapter, that is sold separately for around 130 USD).
As for some quick impressions:
- shells are quite big, but with ergonomic shape, so RIE-1000 is comfortable for me; good quality 4-wired hybrid cable that is easy to handle;
- one of most holographic soundstage for under 500 USD, presentation is very natural and coherent, with nice width and great depth (even better than Soranik iON-4);
- bass is the strongest point of RIE-1000, yet I wouldn't call them overly bassy IEM, lows goes deep, has nice texture, well defined attack and can create strong punches;
- lower mids has nice body, vocals and upper mids are placed more forward, to chive better clarity, but this isn't overdone;
- midrange is natural, just a touch on smoother side with great timbre, RIE-1000 were not supposed to be a detail monster, yet definition and resolution are nice;
- highs has some sparks to them, are lively, but also smooth, extension, level of details are ok and there is some air;
- sound is very clean with dark background, it helps easily pick up instruments positions;
- quite universal model for different music, works best with modern music, but I was stunned how good it plays many jazz and classical tracks;
RIE-1000 has nice synergy with RIE-mini, that helps drive them properly from smartphones, works great with DAPs like Shanling M6 Pro/M8, iBasso DX300. For me works the best with deeper insertion and with eartips with wider nozzles.
