anybody?

I didn't even know that Astrotec had a dual dynamic. As soon as I can gather up $50.00, I'm putting in an order, regardless.

yeah, i first saw them mentioned in the dunu dn-900 thread. people were talking about what a good deal they were for a hybrid at $120 and then someone brought up the astrotec ax-30/ax-35 which i think are going to retail at $70 but there's a presale on taobao right now for $51 that's up right now. i might take a jump on them as soon as i can gather up the money as well as i really like the fit and finish of them and i don't own a hybrid yet.

is this a dual dynamic or a single ba/single dynamic?

i believe it's a single ba/single dynamic hybrid.
 

Educated guess. They're essentially identical with respect to drivers (in fact, the BA driver is identical, both are confirmed to be using the ED-29689), except the AX30/35 is quite a bit less expensive (399 RMB, or ~$65 USD, give them an international markup, and it's probably still <$80), and there are two tuning choices with the AX30 or AX35. Also, the shell of the AX30/35 is very similar to the AX60, which is near K3003 in quality. The one thing I can see the DN-900 having an advantage is the Pelican case and the cable, which looks better, though I actually think the AX30's cable is improved over the AX60's.

found this in the dunu dn-900 thread.

also this:

I just checked a couple of days ago. The 30 is $50(299) and the 35 is $65(399) IIRC.
 
I didn't get the impression that these lower models have the filters. I think the 30 is one sound and the 35 is the other. Seems you have a bassier AX30 and slightly more refined AX 35 with more treble presence.
 
Need more impressions, I guess, but doesn't sound like the DN-900 is for me.

I agree with you on all those things. It's just that some of the "old timers" here start to think that their opinion of audio is the only opinion that counts, and if someone is new to head-fi or any other audiophile forum, that the opinions expressed are somehow less valid or carries a "worthlessness" to it. See some of the comments on other threads for proof of this. It's like if Jaxk Oldtimey says the Palooka T2000 is the greatest IEM since the stone age, and if anyone else DARE to say "You know, I tried the Palooka T2000 and it just didn't seem to ring as true for me." Then you get the resulting posts with "well who cares about your opinion" and "I've been listening to high end audio for a hundred years, and so have my head-fi buddies, and they like the T2000, so you sir or ma'am are WRONG." It gets to that type of response, which is sad. I think this place is fun when we get the differing opinions, we share our discoveries in earnest, and provide comparisons and opinions, even if they are against the popular belief. That's when this place gets interesting and fun. Not when people get so darned sensitive about their "favorite" IEM.

My question (see below) was that you are now implying fact without supporting it, not an opinion.

I was pretty much set on the Sony H-3 too, until I saw the measurements on goldenears and innerfidelity, and that they measured  below or at the UE TF10, Astrotec AX-60, and the Sony XBA-4. For a $350 IEM, with hybrid tech, I expected them to rate at least above those IEM's, and give me some WOW factor, but not measure slightly above the RE-400 and UE 900. I can get the UE 900 for $280-300, the RE-400 for $80-100, and actually pay less for the AX-60. I hope they blow your mind though when they arrive? eric seems to be in love with them? Let me know how they truly rate when you get them?

What innerfidelity measurements?

And how do they measure "below" any of those other IEMs?

I just don't know where you're coming from on these statements.

It just doesn't help your credibility with me personally that you make claims based on science you've shown no history or indication of being well versed in, didn't substantiate them, and then chose to ignore a request to do so while redirecting around it. I obviously only speak for myself but maybe others will see it similarly.

He's right.

Take a look here at the before and after response applied by Accudio.
http://en.goldenears.net/26285

The actual response is very colored, but the EQ corrected response looks fantastic. At $300+, that blue corrected line should have been the natural response.

As a stickler for flat response, that graph killed any idea of me purchasing it at its current price as well. Maybe if it hits $99 someday I'd give it a go.

I can count on maybe 1 finger the number of IEMs that have a published measured, compensated, FR even close to that corrected line without EQ. And as far as I can tell, you don't own it.

Which part is he right about?

Sorry if This comes off as sounding rude, that's not my intention.

I'll stick with my OM Audio, my DUNU, my UE 700, my Piston, and my Kavi B3. I'm sure with all of them, they can cover the basses provided from a $350.00 IEM.

But how will you know?

 

[eke2k6]

Easy, tiger.

 
The problem that you're addressing is just part of human nature. I have the same problem with friends suddenly thinking it's ok not to vaccinate their kids.
 
@bhazard, that corrected blue line is actually a hot source of debate circled around the etymotic er4s. have a read in that thread to get an idea of the diffuse field response. I'm personally of the opinion that the df response is not actually neutral.
 
@iemagnet, check out the measurements for the XBA-4 and TF10. If they still sound good to you, then maybe there's no real way of saying something measures "below" another iem.

I loved the TF10 despite measurements... but keen to hear it again. It's been a while!

It's cool, I understand. You are right though, very few, if any iems have a response like that, and if they do, you have to pay a fortune for them. This is why I dislike most iems, or how there are iems out there that do this, but aren't measured and we just don't know they exist.
 
I built a speaker with such FR. This is the measured response pre-crossover modification. Despite the 18khz roll off, I haven't seen a headphone or IEM come anywhere close to this (which sounds exceptional). Post mod with a driver swap, I extended the FR down to 25hz within -3db. In room response measured at 19-20hz -3db.
 

 
So I do own audio equipment with a similar response, and I know what I like. If the H3 was $99 or under, I could see myself trying it on a whim, but for something costing $350, I need to hear it first.

     If I may chip in my two cents, I think vwinter does have a point. As far as I know FR measurements are highly dependent on the measuring equipment, environment, and basically the end user; therefore, no one can be sure that there is a standard. Then you have to factor in the more complicated s**t like driver resonance, etc. which (in my opinion) could not be accurately measured with even the most sophisticated equipment (Golden Ears' HATS doesn't seem all that trustworthy). So in the end, IF and GE's measurements can't really be trusted fully as a reference, because there is no standard.
     Moreover, why or how the H3 (or any headphone for that matter) is rated "above" or "below" another headphone is beyond absurd. Basing one's perception on frequency response graphs and comparing them with other headphones based on their FRs alone is just crazy. It's not like you know how a headphone sounds from that FR alone; there is a lot of physics going on (drivers, housing, and s**t I don't know and don't care about) that makes the experience of listening to headphones.

All that said, but if it was Skullcandy or Beats that were graphed in the sane way and the measurements were not to the desired "lines" or FR, it would be taken as FACT here. I read so much b******t above with some of this, that I rescind my statement. The H3 sounds like golden lyre and a choir of angels. I read time and time again the experts posting FR graphs, and taking about Rin and Tyll like their findings are biblical, and anyone who suddenly comes to me and posts that I'm full of it for saying that can stick it, because it's 100% true, and now the FR graphs don't mean crap because I happen to mention the H3 not measuring up to some well known cheaper IEMS?? I'm sure glad we got the Piston 2.0. We can all agree, these are the second coming..and the VSonic GR07 will be knocked off its dynamic pedestal

Cheers all!! <3

Anybody have any experience with Nuforce?

I'm actually pretty excited to be getting the Sennheiser CX 150 back. Those are a super comfy pair, and much more balanced than your typical CX line of IEM's. I sold off my CX215 to JoeDoe, and he loved them, as did I. It'll be sweet to play these 150's through my X3.

Bought the yuin pk1 on impulse XD

did you get them?

I wanna hear them for 1st time, just cant find them at a cheap enough price that warrants a purchase.
