iPhone 5C and 5S: audio output - Page 20

post #286 of 350
Has anyone tried the line out of a 5s from the apple dock into a decent headphone amp?

Just wondering whether best spend on a desktop amp rather than amp/dac if my main focus is musicality.

Thanks

Strange, I have an EU 5S and I have no issues with volume, unless, where I am using the IE800, they're just crazily efficient...

I'm toying with the idea of adding a meridian explorer to the mix, could be good, just not sure if would be better to spend the extra cash on something like the Fostex, to use the native digital output rather than through the CCK...

I already hooked (for testing purposes) my iPhone 5s to my iBasso T3 via Lightning to 30-pin adapter.

 

Quality wise i don't think i got any improvement with neither my UM3x or SE215 since the 5s hpo already has stunning quality. Obviously what i got was a ton of headroom and volume available if needed.

 

On the other hand i hooked the 5s to the T3 via headphone out and the sound was fuzzier. Hence i don't buy the theory that states that double amplification does not hinder clarity.

 

BTW i don't have volume problems with my 5s and my iems but i had more headroom with my old 4s and 3Gs. And with certain headphones & recordings this extra headroom can come very handy.

If the meridian doesn't have an internal battery, it could suck your iPhone battery down pretty quickly via cck.

Preamping is essentially double amping. Portable dacs use opamps to amp up to line out voltage. Some even advertise which opamp is used, so you know what flavor of sound you may be getting. Other dacs may use discrete fets, which are still a form or amping. Some complain certain daps line outs are less clean than their HO. There's a lot more to the equation than just simply double amping.

The apple lightening 30 pin adapter has its own wolfson dac that you may or may not find inferior to the iPhone dac.

Size-quality the 30 pin adapter is quite remarkable imho. Ergonomy goes a long way in my book.

 

Anyway with efficient iems and the iPhone 5s i don't think anything else is needed to enjoy a magnificent sound.

FWIW, I will mention that the JDS Labs C5D Amp / DAC combo which uses the CCK (actually called the "Lightning to USB camera connection cable) and USB Audio Class 1 sounded very good to me, used pure digital out from iPhone Lightning connector, and more importantly, had a "battery" mode which reduced the power draw on my iPhone.  In my experience, though, it still DID draw down the battery a bit--about 1 percent per song, which is a runtime of approx. 400 minutes, significantly less than the native runtime using the HO.  Plus, you also have the added PITA of having to go from CCK to micro-USB cable, with the CCK terminating in a huge female USB end, mating with a huge, fullsize male USB end, which then goes to the C5D.

 

In something like the Fostek or Sony or the HiFi M8, you just use the Lightning charging / synching cable--and there are off-the-shelf short ones available--to connect to your amp/dac combo unit.  Much more elegant.

 

I sold my C5D because I felt the improvement wasn't enough to justify the extra hassle and the SQ out of the 5S was so good with my ER-4S's and HD595's.  But if I ever decide I want a portable Amp/DAC again, I will definitely go for a CEntrance HiFi M8.  It can drive most anything and is a registered Apple MFi device.  I figure in for a penny in for a pound.  Or nothing.  Which I am quite happy with.  LOL!

So . . .

I have something improbable / questionable to report:

Apple replaced my iPhone 5s under warrantee (Touch ID issues) and my new one sounds better to me! I sat bolt upright last night after I had listened to a few songs and was like "no. Can it be?"

The improvement--actual or imagined--is in the trebble: this new one doesn't have the slight edginess or aggressiveness and at the same time retains all the goodness of my previous one.

Real or imagined I don 't care--I'm loving the sound even more, especially with the Etys. Awesome.

Could just be a later FW.

That's strange.

 

In the last 10 days i got my 5s exchanged for a brand new one twice and both of them sound exactly the same as the first one. That is very good and that is less loud than my former iPhone 4s.

 

The reason for the change is that from time to time when listening on headphones the volume 'autolocks' to maximum level and you just can't regain control over volume unless you restart the iPhone.

 

I almost got my eardrums blown the last time since i was listening to the UM3x that are uber sensitive and i was wearing gloves so it took me a few seconds to pull out the iems.

A few days back i purchased a used 4s in order to properly compare its sound with the 5s. At times i missed the warmth of the 4s...

 

Well...there's an important difference in sound signature already commented here. But may be it's more pronounced than i was judging from memory.

 

The 5s mids are more forward and it has less subbass energy where the 4s mids are not as in your face and its bottom end is clearly thicker.

 

In the end i think that the added warmth of the 4s is more forgiving than the added presence from the 5s.

 

FTR the EU iPhone 4s under iOS 7 is almost two clicks louder than the EU iPhone 5s hence the EU headphone amp limit does only seem to be in place from iPhone 5 on (And i'm talking about a cap different than the one from the Music menu. An added cap that the end user can not override)

post #296 of 350
Jailbroke my 5s and set the amp gain to non EU levels. Boy what a pleasure getting exactly the same output power of my non capped 4s.

If any us reader has a jailbroken 5s pls send me a pm


I don't trust anyone who smiles before 9 am

Helo again, I bought yestarday iphone 5s 64gb EU version and could confirm, that the sound is excellent, even better than the previous iPhone 5. Have a nice spring day (me with flac Luciano Pavarotti and GR07 ear) :o)

post #298 of 350

If any owner based within the (annoying) EU wants to uncage the amp of their 5s here is what i did. And it's working wonders withou drawbacks of any kind (Aside the JB).

 

1. Jailbreak

2. Add to Cydia the repo from hackmyiphone

3. Install the EU Volume Limit Disabler from that repo

4. Reboot

 

Now you have got rid of the annoying yellow/red squares and from screen turning on when you get loud

 

Then:

 

1. Install iFile (from cydia)

2. Through iFile go to  /var/mobile/library/preferences
3. open the archive com.apple.celestial.plist%
4. go to volumelimits/headphone and change  1 for 1.2
5. reboot

 

Now the headphone amp from your 5s is not capped. It will get as loud as an iPad Air or non capped iPhone 4s. And that without adding any audible distortion or audible raise in the noise floor.

 

Even if people don't know the EU has set a double volume limit (measured with bundled earphones):

 

1. 85db (if you have the Music Setting toggle EU Limit set to On)

2. 100db (If you have the Music Setting toggle EU Limit set to Off)

 

That is for the Earpods. Problem is that non EU iPhones/Touches drive the Earpods to far more than 100db. Hence even turning Off EU Limit on the menu you are chained to the second volume limit set by the CENELEC. Your amp remains capped. Less capped but capped nonetheless.

 

The regulation is stupid enough that when earphones are not bundled with the player there is no cap since the amount of capping can not be assessed. Hence: iPads are no volume limited within the EU.

Do you honestly need that extra volume? I can understand if you have hearing damage but anything above 75% is freakishly loud on any of my cans with the 5S. I'm just trying to understand why someone would need to remove said cap.

post #300 of 350
Just try to listen Songs From A Room from Leonard Cohen or Honky Tonk Heroes from Waylon Jennings with non sensitive iems.

Believe it or not there are albums out there with lots of dynamic range and very low intrinisic volume.

Certainly i won't need that much headroom to listen to the latest Chili Peppers record.

Besides that as a consumer i will never accept watered down products at non watered down prices. I want the amp working as designed not capped by some burocrats who think that are blessed enough to rule what amp voltage would i need to stay safe.
