My SA6II from Hifigo arrived a couple days ago. Have been listening to it next to a kilobuck IEM that I am reviewing. You can find my unboxing and graph video here:
The tuning switch effectively changes the tonality from a W (off) to U (on). I personally leave the switch on because the soundstage imaging has more depth with orchestral and cinematic music. The technical performance is very high, easily outdoes some lesser kilobucks. I’m also impressed by the BA woofers. It does lack a bit bounciness of good DD bass, but it’s crisp and dynamic. Strongly reminds me of 64 Audio BA bass. From memory, this MkII outperforms the original version on the aspects that I care about the most (detail, resolution, staging). The IEMs look good on camera too. I will enjoy reviewing these IEMs a lot.
