Yeah I would agree with you there, the iphone is a bit muddy if using the internal DAC and even when you connect an amp via the headphone jack.  However, I would say that there is a significant improvement if using the line out (via the bottom charging point) into an amp as you are completely bypassing DAC stage of the iphone.  In which case, all you're really listening to is the amplifier.  Still this option isn't nearly as good as connecting the portable amp to a real DAC.  Anyway, I cannot wait for that review as it looks like a very promising product!

I thought that with iPhone to LOD to amp, you're just bypassing the iPhone's internal amp, but don't bypass its DAC stage?

 

EDIT: sorry, this is getting off-topic

Hmmm I thought it was the other way around, but you may be right.  Joe will sort it out when he gets back on haha then the thread can continue back on topic wink.gif

Using an LOD pulls the signal directly off the DAC, bypassing the amplification section. That's why the volume control will no longer function - it's a line-level signal. 

 

IMHO, the DAC section on most iProducts is stronger than the amp section. The amp is the weaker link. Of course, DAC can be improved upon, but it isn't as terrible as you might assume. 

 

Anyway, back to custom talk!

The reason that an LOD isn't always the best is that it doesn't do a pure bypass, if you get what I'm saying.  I don't know all the technical details, but I believe that it force a maximum volumes on the iDevice allowing you to get all the data from the music or something of the sort.

Yes, they look amazing!  Ambien Acoustics didn't send me the full accessory kit, so it comes with much more.  So far with my limited listening (very limited) listening, the AM4 pro sounds quite nice and balanced with bass when there should be bass, balanced mids, and quite balanced treble.  I still have to see exactly where is stands in terms of performance, but it is at least worth the price.

Most dedicated amps should outperform the iPhone via line out, and I have yet to hear one that won't.  The iPhone is decent for the all-in-one functionality you get though, but a Sansa Fuze (not sure about the new ones, though) line out is cleaner than that of the iPhone.

It depends on which particular iPod or iPhone you are talking about.  The older iPods had a large disparity between the line out and headphone out in terms of resolution, but even the line out still has an amp section.  The iPhone 4 and 4S both have close to the same detail levels (and the 4 has a better amp section than the 4S) via line out and HPO, but the line out has a much higher output impedance which is designed to match with line level inputs.  Also, the DAC amp section is again different than the HPO amp section, which is designed to drive a wide range of headphones vs. a much easier to drive source, and to put it simply, the line out is a cleaner less altered signal.

So are you saying that iPhone line out in and of itself is not good?  Or iPhone line out into one of the aforementioned portable amps is not all that good?  Bit confused on that point.  I would agree that the line out is pretty bland, better than using the headphone jack, but isn't that the point?  If it were a highly colored signal than you might as well use the headphone jack and be done with it.  Otherwise, take the semi-neutral line out signal and "upgrade" it via a portable amp, bearing in mind that the amp is highly dependent on the source it won't be spectacular but it is certainly better than nothing.  Any amp will sound better via a dedicated DAC but the selling point of these portable amps is to upgrade the sound of your portable gear, whatever that may be. The better the portable source, the better the portable amp will sound.

The quality of the line out is not far off from that of the headphone out in terms of detail/resolution, and yes, the line out is more neutral.  What I am saying is while an external amp will improve the performance, micro-detail that to me makes CIEMs really shine is lacking, and the amp can't add it back in.

Mmmmm I see, yes I would have to agree with you there. Guess I'll have to start looking at the iMod rolleyes.gif

post #1660 of 4815

Hopefully you'll get time to review the AM4s soon:)

If you are happy with the iPhone...

 

I am just here to plant the see of better sound, but if you haven't heard better, than the best you know is the best, so you aren't missing anything tongue_smile.gif.  I am sure I could spend more and improve over what I have, at least at home at my desk.

In due time and I review them as I receive them and I am finishing up my amp reviews.  I can tell you the AM4 pro has a very balanced sound signature that is not bass heavy, but has plenty of bass when necessary and isn't bright (but brighter than the Alclair Reference) but not lacking at all.  The midrange is a bit forward of neutral, but about where reference midranges seem to fall.  I have to do a lot more listening to really know where it stands, but so far so good.

I am so looking forward to your review of Heir audio 8A. How warm they can be?  I guess they are warmer than LCD 2. are they warmer than EM3?

post #1663 of 4815

I have been debating a set of CIEM for a while now and this is the first complete list i have found to be really helpful.. I have the iphone 4 and the fiio e7 dac. I was wondering which CIEM you all would suggest for that set up costing under $400. 

 

I should mention is listen to a lot of house music..

I just posted 3 amp reviews: Portaphile 627, Epiphany EPH-O2, and Headphonia Headstage Arrow 12HE 4G

 

Also, check out the thread for the just announced Unique Melody Platform Pure 6, which has a box with a DAC, active crossover, and amp going to a 6 driver 3-way custom IEM.

The 8.A is brighter and more airy than the EM3 Pro!

It depends on what sound signature you want.  For example, a reshelled TF10 with an aftermarket cable performs quite well and can be less than $400 if you want that sound signature.  The JH5 would be similar and gets good reviews, but I can't say from personal experience.  However, the Rooth LS2 does fit the bill and I have heard a demo, which sounded quite good.  The Aurisonics AS-1 is another option and quite different in the sound signature.  And there are others such as the Heir Audio 3.A, which of course will then tempt you with the amazing looks you can get.

 

If you can stretch to around $500 there are quite a few more options, but if not, you should be able to find what you want.  However, the first step is to let us know the sound signature you are looking for and anything else that is important in your buying decision.

Hey average_joe,

I'm interested to get the HT6 but I was wondering how long did it took for you to get your HT6 after sending your impressions to hidition. I'll be in Korea from mid July so I was hoping that I could collect my HT6 when I'm there if I were to place an order now.
