Headphone collection:

Panasonic RP-HTX7 

HD 558 w/ Foam mod

fostex t20rp mkii (non modded)

 

Devices:

Fiio E7 (with no Aux in jack - it broke so only USB)

Fiio X3

 

Questions! (Warning they may be stupid ones I'm still learning here)

 

Assuming impedance is ohms, dividing headphone impedance by 8 is the maximum ohms you can give the headphones without loosing any degradation?

 

Does the X3 & E7 auto detect the correct power , voltage , impedance? and is it always most accurate (if not is there anyway to control it?) or is it depending on volume and low-high gain. 

 

Before playing a song on my X3 always hear a small click, this happens everytime a song changes or new headphones are plugged in.. Something to be concerned about or not?

 

My Panasonic RP-HTX7 sound just as loud on my X3 as my E7 (e7 using USB), Why?

 

The X3 / E7 cannot power my fostex t20rp mkii at any decent volume. My dead JVC receiver which was made in early 2001 was the only unit that could make them vibrate and sound LOUD (volume control went from -100db to 0db) and loud was at -5db before it distorted. They also made my HD 558 vibrate so much that it was hitting the plastic casing. The question here is what receivers / amps are recommended for these headphones to output really loud volume like my JVC? Would really like to hear my Fostex again but nothing can push them!

 

 

Thanks!

 

I don´t know the other headphones you mentioned but I can confirm that the HD-558 sounds very well on the X3.

 

The FiiOs usually have an output impedance of less than 1 Ohm. So they will drive every low-impdance headphone - including IEM - without changing their frequency response. High impedance cans like the HD-600 will be driven equally well. Not by the E7 but by the X3 (-> high gain activated). The amp of the X3 is extremely powerful.

 

The small click on the X3: do you mean a click in the audio output or on the device itself? In case of the latter, it´s a relais inside the X3 that un-mutes the output (actually, there should be two clicks).

 

Regarding your JVC receiver: it could very well be that it not only was extremely loud but also quite unstable. Headphone outputs on older amps like yours (or my own Sony) have a ridiculously high output impedance ranging from 100-200 Ohms. Not only will that create a very audible frequency error on headphones susceptible to this (like your HD-558), the output will also loose control of the diaphragm, leading to the creation of distortions. They could have been responsible for the vibrating shell of the your Sennheiser.

The clicking is a known issue with older Firmware (FW) and I think 2.1 and 2.14b sort of fixes that.  I can't remember what was the cause of it, but no, nothing to be concerned about.

 

 

Not quite sure what you mean by that.

 

 

You are going into amp pairing here and you would need to go else where on the forum for this.  But generally, a lot of headphone amps big or small on the market can do what I think you are trying to ask.  IMO, being super loud isn't already the most pleasant or the healthiest way to listen to music. Hope the best of luck on your amp/receiver search.

 

Thats funny because I always have high gain enabled. I can't even listen to my HD 558 with "low gain" even at max volume. 

 

The firmware is updated to the latest from the website. It clicks only when headphones are plugged in, sounds like almost it's turning on and off the amp kinda like a receiver when it turns on and off you hear that "click"

What would be a recommended setup to push my Fostex than without getting distortions and loose control of the diaphragm. The sweet spot on my JVC with fostex was -5db on any song, the headphones vibrated so much to the bass but the mids and highs sounded so balanced at the same time... my ears orgasm everytime!

 

 

Another question not related to my x3 or e7, however about headphones. Is there a limit to headphones when it comes to 16-/24-bit & 48/96/192khz music? could my HD 558 output 192khz-24-bit audio?

Are you sure your headphone isn't busted from all those vibrating you described earlier?  Your headphone shouldn't "vibrate", if it does, you have your volume way too high and it might have damaged it.

um.... I don't know. Maybe it is what Marlene said about un-muting from the amp chip?

It wouldn't matter. Headphones is essentially translating electrical signal to air pressure.  So, it doesn't matter if it is low quality mp3 or HD audio like 24/192, headphone is just translating that signal into air pressure into your ear.  The only thing that matters is, if your ear can pick up the difference or quality of the different bit rates because 24 bit only means that more signals can be stored in one file and you can technically hear a little more that 16 bit and/or compressed audio cuts out.

Wow. This is the most perfect analogy I´ve ever read.

A few suggestions,   

1) Don't get too wrapped up in resistance specs, the X3 is designed to drive most headphones within reason, I'm not sure how tough a load your Fostex is but it may want more power from an external amp.

2) The amp in the X3 is fairly similar to the one in your E7, possibly even a bit better, which is why  you may get similar results from each one. The E12 would give a significant bump in output power and might be what your Fostex needs. It works well with my HD 600's which aren't the easiest to drive headphones in the world.

3) An external amp isn't just about increasing your volume, It should also improve your sound quality, if it's a decent one.

The 2.14b firmware has the same Library size limit as the new 2.0FW for the X5. The limit is 5800 tracks. This needs to be increased in order to take full advantage of large amounts of memory that can be install now with the 64 and 128 GB microSD's.........Jim

For what's it's worth the E12 has more than enough power to drive my t50rp. It's a really nice combo with the x3 and the Fostex.
post #9983 of 17129

If I remember correctly, the T20rp is a step down from the T50rp.  With the current beta FW with the volume mod, I have mine at 70/120 and find that enjoyable.  Its no harder to drive than a HE-400 or so, and maybe a little more difficult than my hd700.  Mine is unmodded, just using swapped out earpads and a different cable (the stock cable was non-functioning and it was simpler to pick up a new cable than go through the hassle customer service was giving me.)  I don't really think I'd enjoy the experience I'd get from maxing out the volume on these to get a rough idea at how loud it can get.  Either way, while I have not heard the T20rp, I suspect if the X3 can drive the T50rp well, the same can be assumed for the T20rp.

I don't think my headphones are busted my hearing isn't all that great after many EDM shows. "low gain" at max volume sounds to quiet for me and at high gain "60" volume works pretty well! but almost feels like somehow could push little bit more out of the headphones (not much but little bit more)

fostex specs:

 

  • Frequency Response: 20Hz - 30kHz
  • Max Input 2000 mW
  • Impedance 50 ohm

 

The impedance is the same as my HD 558 but when it comes to volume it's night and day comparing to my HD 558. The fostex plugged into my X3 sound like plugging my HD 558 into my android phone the volume just isn't there.

That could be the sensitivity to sound is a bit different.  I don't know, it just sounded like it's that way.

I will have to try out E12 I guess

 

I just upgraded to http://www.head-fi.org/t/651769/the-fiio-x3-thread/9405#post_10489378 FW with the "volume mod". Gotta say nice UI and can customize the EQ little bit more.

I get that very slight pause with gapless too. Considering that before the latest FW, where my X3 would often freeze, it's not a big deal. (And this FW is still beta.) I think I might just get the slight pause with mp3s, and not ALAC (my music library is still iTunes, so that's how I store lossless) or AAC. I'll have to try to notice if it's only mp3s or not.

Tiesto's in search for sunrise (1-7) (still listening to 8-11) is mixed so each song has to be played as gapless and this device does it pretty well. MP3 320kb & FLAC both have no small gaps with it enabled

If I understand what you are asking here, is that the X3 would need to read all the ID tags on all your files and assuming you did properly input the names of files and go by that alphabetical order? I think by default it reads the root file names and sort order by that in the browse menu. Other than that, it pretty much follows normal audio player convention and sort/search by album, artist, and genre. Don't think you will find too many people would want things to play at that kind of sorting order. I think most of us using the X3 sort our files with album folders. I have 1 card with my absolute favourites but that was done so that I am going to leave it on shuffle.


I'm really not used to shuffle. It may only be because I am used to my old player. I used to use the iAudio X5L and when that got to the end of one album, you could set it to automaticly move onto the next one (just as I said, in alphabetical order). When it gets through all of one artists albums, it just moves on to the next artist without me having to do anything. With the X3, it just stops at the end of an album. Maybe it isn't a normal thing for a media player to have but it's just not what I am used to. I think I will try and do something similar to what you said sometime.
