I am sure some of you will love this news: SA6R and SA7 @ IFA Berlin.
You may underestimate what the SA6 offered. The driver used is an interesting one. It does two things that are hard for a lot of BA earphones.
1) It offers an unusually natural presentation, as in speed, dynamics, note thickness, etc. It doesn't specifically sound BA like. The only other earphone that I've used that is like it is the CK90Pro. The SA6 response really well to EQing too, so the low end can be bumped up and end up being quite natural and extended. The treble is not fixable. It is smooth and laid back. Intensity wise, the treble isn't even rolled off. It's actually a little hot, but he presentation is very laid back making it sound rolled off despite the sensitivity being there.
2) It offers a sense of openness and air. SO few earphones do this. While the sound stage isn't great in terms of placing a sound in a pinpoint location in mental space, it is open and completely transparent. I have not used another earphone that's been as good in this sense, not one.
I do agree there can be improvements and the big issue was the single driver and inherent limitations with frequency response range. A dual driver seems quite needed to effortlessly cover the hearable spectrum. The SA7 should fix this. Oddly, I kind of expect the SA7 to approach something more like the SE530 in setup. The SA6 is mid centric to start with, like the SE530, and Sleek Audio seems to want that gearing. I will be curious how they tune the dual driver setup.
I never though the build quality was bad. I thought it was quite good actually, at least for such a compact device. For what they were trying to do, they did well. I feel it's less fragile than people think. The new design is even better. It seems a big goal was to develop a product that is very tough and picked some smart design choices.
I am also curious what Sleek Audio has up their sleeves designing the drivers like they are. This opens up the possibility to swap in different drivers into the earphone. Want the ER4 driver in a SA6R/SA7 package with port tuning? You might be able to.
Yeah I know it says it does, but from the picture dissecting the SA7, they didn't label any bass-tuning port.
BTW, do you think the SA6R will replace the SA6? If so I hope prices drop so I can grab one :D
They probably just forgot to put it in the animation. As you can see in the SlashGear preview, the bass port is still there.
Very likely yes. But my guess is the initial price is not going to be lower than the current SA6's MSRP of $250.
I was thinking the same too. TF10 also have similar size I think. By the way from my little experience grill wax-guard is usually used in dynamic IEMs.
You're exactly wrong. Our resident audio engineer Kwkarth explained it a while back. The nozzle size is one more feature of an iem that helps tune the sound--smaller nozzles help to bring out the bass (something that engineers working with a BA iem often want to do, but not always), while larger nozzles allow for more treble presence (something that a designer of a dynamic iem might want to do, but not always). Again, it's just one factor. Someone can link to the explanation or you can search for it.
