I've been listening to the DZ8's a lot and they are very, very nice. 2 BA drivers that deliver amazingly textured and slamless, fatigue free bass that is tight like
your average 2 BA like ATH-02 or Rockit Sounds R50 etc. There is no mid bass bloat and mid-bass and sub-bass levels sound really even. Sub bass extension dosn't go as low as SW3
or push any air but does great for BA bass. Say if SW3 sub bass goes down to 30HZ then it sounds like the DZ8'S bass goes down to 70 or 80HZ if I were to guess.
2 Mid drivers that at this stage does not make the mids forward or recessed to my ears. Not slightly forward like the DZ9.
Sibilance is nowhere to be heard with these or the DZ9's. 2 BA for highs and 2 BA's for ultra highs, the highs, like the mids don't sound enhanced or recessed and extend well.
Never sounding harsh, they are polite but not lacking. Detail levels are off the charts from bass to highs and soundstage is very large with separation and imaging killer as well.
Definately soundstage size is amongst the biggest I've heard, especially height.
This iem is another winner like the DZ9, very similar technical levels and the main difference is the mids not as forward as DZ9 and the BA bass of DZ8 has no slam which makes
listening for hours easy as warm American pie. DZ8 is not warm and smooth and not cool or clinical sounding. Just clean and transparent, so much so that you could test DAC's with them.
No dips or peaks that I can hear. I'm cooking up a review of the DZ8's but I am very impressed with Gleam Handwork Design. Its 2/2 so far.
