Dunu DN-1000 - Dunu's hybrid IEM - Impressions thread - Page 131

post #1951 of 2483
So I've been reading this thread all week and I have a question before I buy them. As soon as I get an answer I'm pulling the trigger. Will a 2014 moto x be a good source for these. I do a lot of listen with this phone and I don't have a portable amp yet. Thanks.

Power wise you shouldn't have much problem as these IEM are easy to drive. Can't tell you how they will sound though. Even Sansa Clip Zip with rockbox brings pretty decent sound from DN-1000.

Hi h20...if I'm not mistaken you also own the Yamaha eph100 and listen to trance? Me too on both counts! I may be mistaken but i think i read a lot of your posts vefore buying the eph100. But if I'm right then u are just the one I want an opinion from. So here's my question. Do you consider the Dunu 1k a worthwhile upgrade to the eph100 and what are the major differences. I just purchased the eph100 not long ago and I like them a lot in imaging soundstage ect. What I feel they are lacking is proper decay and texture in the treble as well as I would be OK if they actually had a bit more treble and clarity and shimmer in the vocals.I mean I'm really loving the eph100 but my previous pair of iems had really great trebbke and vocals and even though the eph100 has that amazing soundstage I wish they were a bit more airy and articulate in the treble. So how does the dn 1k fair in this reguard. Does it do the things like imaging and depth as well as the Yamaha but also does it give more clarity, while keeping an overall similar yet brighter character? Thanks.

Yes, I was quite active in the EPH-100 thread, it was a decent IEM though DN-1000 is an upgrade in many ways. Firstly, the treble will be what you're looking for, it has more presence compared to the Yamaha. They're going to be a touch brighter and emit quite a bit more clarity and detail. (quite a lot more). The soundstage is wider and separation stronger. I think I said a few pages back EPH-100 can't really compete with the Dunu. Its an upgrade in every way and a big way. (100%)

Yeah....this is exactly what I was expecting to hear. I should have just gone straight for the Dunu dn1k to begin with. The extra 60 or so bucks would have been better spent up front before I got the EPH 100. I'm am still worried about the quality from the moto x though. In this thread someone mentioned that their HTC one didnt work for these. I don't know much about impedence and I searched to find what the moto x specs were but I couldn't find out impedence anywhere. So I don't know what to do. I'd hate to buy them and then not get good sound from my main source...I really need something that just works well straight from a smartphone. I know that DACs and amps improve a lot of headphones but I'm just not quite there yet in terms of purchasing one of them. I like just plugging into the phone with Spotify on extreme quality setting and not having to deal with an entire other unit. Suppose I could if I had to but I don't have the money right now to but the dunus and a DAC/amp.

I cannot find the output impedance of Moto X, but I found a graph with it plugged into stock Moto X headphones.

Motorola Moto X frequency response

 

See that big drop off at 100hz where it slops down? That's an indication there's quite an amount of low-end roll-off present with your phone. Depending what the impedance load was (with the stock headphones) ideally its not the best frequency response for audio quality and you may find something with low as 10ohms DN-1000 has some problems, possibly absence in bass.

 

Of course, I cannot promise the result though its not looking terribly great.

 

With something like the DN-1000 you'd like an output impedance of around 1ohm, players like FiiO X1, FiiO X5, Sansa Clip+. Its not an absolute guarantee on the results, just a strong guideline. Going from all this I cannot tell you the outcome with Moto X, they may sound ok or quite off with quite absence in lows.

 

Its your call mate, if you can live with a FiiO X1 in your pocket or Sansa Clip there'll be no problems.

Thanks for going through the trouble to do that, but it seems that this is the old version of the moto x which is a much much less premium device than the new moto x. The only thing I could find was a review where a self proclaimed audiophile said the moto x 2014 had great output strength and sound quality. So I'm afraid though that this doesn't apply to my phone. The 2013 moto x wasn't really a "titan" in the smartphone world with its specs but the new one has all the same specs and build quality to compete with the best phones on the market. So the mystery question is, is audio better in the 2014 version. Man this is such a pain....

Alright then, scratch that.

 

If you can find a frequency response chart with your newer model bring it back here so we can take a look. (with the link)

Motorola Moto X (2014) frequency response

 

It's prety clean sounding but the frequency response and stereo crosstalk with headphones plugged in are messed up.

I knew my old iPhone sounded better but I didn't realize there was that much drop off in the low end. This is very disheartening indeed. I may go buy an iPod touch or something for my music needs. I have to have access to Spotify otherwise I would get a sansa clip or something. I may do better to hold off on the dunus and get a better player for my Yamaha's????

iPod touch 5th gen's output impedance is less than 1 ohm. It probably sounds good with most iems.

Will that x-talk affect the rating if its a headphone or an IEM? or its considered uniform across the board regardless of what the output is connected......

My goodness. Why must this he so complicated. I did read this thread so I need more than 1 ohm correct? So it looks like an iPhone 5 or 5s would fit the bill. There should be a universal standard that gets used to keep this from getting complicated between devices and iems. I mean these are iems we are talking about that are supposed to work with a phone or portable player. It seems there should be a standard but obviously there isn't.

Oh so the Dunu needs less than one ohm...I read wrong before my last post.

Yes normally less impedance is better, but I'll let more experienced headfiers here explain why that is.
