Happy new year, discovery folks! It was fun.
This year was interesting to me, hobby wise, since I started to receive some support from manufacturers in terms of samples and reviewer discount. Without their support, I would never be insane enough to go out and buy all multiple sources to try. The differences and, at the same time, similarities between sources were eye-opening.
Best sources this year? Shanling M6 Ultra and Fiio K7.
Best IEM this year to me is the one that I expected to dislike, JD7. Yes, this is a sample that I received from Fiio to review. No, there is no incentive to push this IEM since even Fiio does not advertise them. It’s like they don’t want people to know there is a weird single-DD-in-FA7s-shell IEM to avoid confusion. Heck I even sunk extra money for bling bling cable and case to make the most of these IEMs. Best IEM below the Monarch II, IMHO.
My most surprising discovery is modern flathead earbuds. You know how we try very hard to find soundstage, natural tonality, comfort, resolution, etc.? Good flathead earbuds can give you all that at a fraction of IEM price. In fact, $200 is already considered TOTL in buds world, and boy do they trade blow with TOTL in IEM world. Have a try in 2023! They might be your end-game. Keep your eyes on Fiio and TGXear (made by our fellow head-fier
@tgx78).
Small surprise: TWS can sound satisfying. I’m reviewing Fiio FW5. Yes, software is annoying. Yes, the fit might not work for some. But boy of boy they sound like a good semi-open IEM attached to an AKM DAP. The sound is so spacious and 3D that I can almost forgive the annoying software. Just almost.
I have only skimmed Resolve’s video, but I have absolutely zero interest in hearing anything from the PoS ER2SE shiller (or whatever he fancies nowadays). Now, I’m usually a moderate guy (I hope), so I allow myself an exception here

Btw, on one hand, we have people who have skin in the game, who actually build measurement rig with genuine equipments, who get in touch with Sean Olive all the time. On the other hand, we have a guy with running mouth (and an empty head). I know who to listen to.
But yeah, target is closely tied to the measurement tool. You can’t compare the graphs from different rigs, so you can’t compare graph against target from a different rig either. That’s why you need to be careful when using the autoEQ function on squiglink.
Harman IE target, for example, was built on an IEC711 coupler, so they have no conclusion above 10k, thus they sloped everything down. Knowles redo the experiment with new coupler that is accurate to 20k and found that you need to add a big bump in air region (a.k.a. 64 Audio TIA treble style).
