After seeing some of Coil's immaculate shell work I always thought a wooden bodied ED9 would look sweet, sort of like a shell made out of No. 2 pencil! That is what the ED9 shape has always reminded me of
Agreed.
What I'd love to see from KZ:
1) a line of wooden IEMs with more refined offerings of what they've done in the past.
a - ATE
b - ATR
c - ED9
d- EDR2
e - HDS3
f - HDS1
OR
2) a line of IEMs that use porcelain ZS3 housings (similar to Rock Zircon material) with more refined offerings of what they've done in the past.
The ZS3 housing is so comfortable (for many) that it's a no-brainer to offer more sound signatures and just vary the colors for the model, as Campfire Audio has done with their Jupiter, Andromeda, etc..
a - midnight blue ZS3 (refined ATE)
b - black cherry ZS3 (refined ATR)
c - amber ZS3 (refined ED9)
d- white ZS3 (refined EDR2)
e - silver ZS3 (refined HDS3)
f - bronze ZS3 (refined HDS1)
They could even make a smaller housing for those with smaller ears.
One could argue "why rehash where they've already been?", but I would argue that the best results come from small EQ adjustments off of the waterline. The greater the distance from the waterline, the more unnatural the sound. Most of KZ's earlier offerings (listed above) are different sound signatures based on slight variations up and down the frequency ranges. The aforementioned models were successful for a reason.
KZ could now take those sound signatures and offer the following:
*better resolution
*better clarity
*better separation
*better imaging (KZ's imaging is currently better than most in the budget-fi arena)
In short, more refined.
In addition, sound signatures that would cater to the treble sensitive would be well received.
Sure, KZ can seek out more sound signatures, but we know that the aforementioned ones work.
a - forward midrange, rolled treble (ATE)
b - very mild "V" (ATR) [ZS5i depending on who you ask)
c - more pronounced "V", lots of air (ED9)
d- relatively neutral (EDR2)
e - more pronounced "U", lots of air (HDS3)
f - very mild inverted "V" (HDS1)
g - mild "W" (ED10) [ZS6 depending on who you ask)
As I stated in my first post, if KZ kills off the plastic ZS5(ii) and offers a ZS7(?) with the ZS5(i) sound signature, they could take advantage of the ZS6 aluminum housing and just delete the three face vents. They can find a way to mimic the ZS5(i) sound signature (including crossovers this time) by employing dampening agents.
I prefer the ZS6 to my ZS5 (i), but the ZS5 (i) sound signature appeals to a great many people, just as the ATE does. The ATE is not MY top choice, but it's one of KZ's top sellers for a reason. It's nirvana for a lot of people.
At any rate, it's not rocket science and they don't have to reinvent the wheel.
Finally, I'd like to see KZ branch out, perhaps into planar magnetic in-ears the way Monoprice has. It could prove to be a successful endeavor for them and another huge benefit for us
Just sayin'
