FiiO Mont Blanc/E12 portable headphone amp, 880mW, slim design, full metal case. Bass boost and Cross feed! - Page 157

post #2341 of 3695

With the M100 I found that the E12 was good, but what worked better was an amp that was cleaner .... I LOVED the way the ALO national sounded with my M100 but that same amp was no where near powerful enough to make my Mad Dogs sound good

I understand its just a signal strength thing but is distortion only introduced when the drivers in the headphone are too loud? (maybe I'm answeringmy own question but wanted to check if thats the case lol)?

 

There are two common possibilities of distortion when you max out volume on the source during double amping. First, it could be that the source's internal amp section is clipping at max volume. Second, it could be that the source signal is too strong and causes the amp to clip. To avoid the first issue, generally setting the volume to 90% should work. However, given D1's spec lists 2Vrms as it maximum output, which basically equal to line-out strength and (the RCA jacks are) designed to feed into monitor speaker, I'll assume Audioengine know their stuff and create a decent amp section on the D1 that should not clip itself. For the second issue, or should I say a non-issue, as E12 is designed to take in a line-level signal. So the chance that D1 will clip E12 is zero. If you even find any distortion on E12, just lower the D1 volume a tiny bit until you hear no distortion at all. However, my guess is they should pair fairly well together.

It's still pretty loud for me at the library just past the channel imbalance.

 

Music barely audible [channel imbalance]

 

Music playing at a volume level that's more comfortable for me [channel imbalance]

 

Music playing too loud for me [no channel imbalance]

Why not lower the source volume by say, 10%? I mean, if it's that loud... then certainly the E12 is too much amp. I mean, I don't understand why people are getting such a powerful amp for such a sensitive headphone.

I can't lower the source volume with a line-out dock connector on my iPhone. XD

What was the setting of the gain switch? If it was on 16 dB then you should flip it to 0 dB which is lower gain and that may be what you're looking for.

Ah, yeah. I forget that option.

Surely, you overreached with the E12, when it's been known since the beginning to rival desktop power.

I second this comment.  Fiio E12 with gain switch at 0dB with an iPhone (4) LOD driving M100s plays nice at the volume settings you show.   Not too loud for me. 

 

And interesting discussion -- did not notice the channel imbalance issue before.  Now I can hear it at very soft volumes.

I knew about the Scouter's power level [it's over 9000!!!!!!!!!!!], but at the time I didn't know what power did, nor did I think the channel imbalance region/volume level would be an issue. I guess you can say *puts on sunglasses* I bought into the hype, yeah....

 

Being a portable amp, I was thinking it would be fine for portable headphones and the power was a bonus. That plus the omnipresent cloud of having MOAR POWAHHH to sound better!!!

 

I do tend to listen to music at a low volume level though. There's no need to blow my eardrums at a [relatively] young age. Many a years to come for Head-Fi gear! :D

I think the main draw with the E12 was that it was powerful enough to power typically non-portable headphones.

For that, I would consider the E12 to be a 'transportable' amp for transportable headphones. Something like the Mad Dogs, which scale up with more power, but sound great with an entry desktop amp (i.e. E9K). The E12 would suit this type of headphone.
post #2351 of 3695

I don't understand the concept of "scale up" still. I used the FiiO HS2 to compare the O2 to the JDS Labs C5, and the C5 to the E12. The observations between the amps with the M-100 [a pretty efficient headphone] were really similar to what I experienced with the Mad Dog 3.2 [a pretty inefficient headphone].

post #2352 of 3695
I, for the most part don't experience much differences from SS amp to SS amp. I, however, hear better depth and energy out of some headphones with better gear. The AKG 70x is probably the headphones that scaled up noticeably from minimal amping, to better amping. The MD 3.2 also had at LEAST a better depth and larger air space with my better amps, though the sound signature remained the same. It sounded congested and boxed in with less power.

I won't even get started on the HE-4, which shouldn't be plugged into anything but the strongest of amps. That scales up basically because it NEEDS so much power to even get going.

Same here, at the lowest settings of the volume pot. It doesn't really affect me.When I use my HD600 I'm on the 16 dB switch and still turn well past that point. My other cans and IEMs that I use with the 0dB switch also go well past that point on the volume pot.

Miceblue never answered the question about the switch, If the switch was the problem, it may not be a real problem if he flipped it to 0 DB.

post #2354 of 3695

Oh that question was directed at me? I thought it was the other person. But yes, I never switch the gain since it's too much effort for me to get a sharp-ish object and slide it. That and even with the Mad Dog, I never had to go past 12 o'clock on the potentiometer, so having the higher gain seems pretty useless for me.

 

Crossfade off, gain on "0 dB," bass boost off, running on battery.

Your M100 is 103dB/mW, my FAD Heaven VI is 112dB/mW - and E12 isn't too loud for it.

ATH-ES700 at 104dB/mW also sounds great.

May be your M100 or E12 is not functioning properly?
