instead of the links can you write down which examples you originally added? I'm intrigued 🙂quadpatch said:The E11 is better than the E7 as an amp (because that's all the E11 is) but if you use the E7 as a DAC as well it will trump the E11 on SQ.
Come on WHF, can you post all the stuff I wrote out here? I put down loads of useful info and links!!
the USB connection is not needed as I will be using an iPhone 4 thanks for the input though 🙂diy hubs said:I use the Firestone Audio FIREYE 1 sounds great with my Grado SR 80 i headphones. It is charged via usb. I bought it from Russ Andrews website and comes in at your price bracket. Cant comment on any of the Fiio range as I havnt heard them.Hope this helps.

Just realised what I posted there. Sorry DIY hubs you were saying it charges via USB which is fine! I'll have a look at it, thank you!gbhsi1 said:the USB connection is not needed as I will be using an iPhone 4 thanks for the input though 🙂diy hubs said:I use the Firestone Audio FIREYE 1 sounds great with my Grado SR 80 i headphones.

I avoided this recommendation because the OP was only looking for an amp and the E7's amp is not brilliant (E17 is much better). As far as quality from an iPhone goes since the DAC cannot be used the sound quality cannot be improved (only boosted in volume). Only connection to a computer will improve the sound.johnnydepp said:DAC/ Amplifier combo, it increases sound quality. E7 also appears to be better built.
Mine does this too, very annoying.ESP2009 said:...................Snip.................
and mine at least loses its battery charge relatively quickly if left unused for a period. Even when attached to computer via USB, it won't function until the charge has built up to a certain level.

Really, why can't it be improved ?quadpatch said:.................snip................

As I understand it the external amp will only be amplifying the signal from another amplifier. If your volume is already fine from the original amplifier what is the point in amplifying it to the same volume with something else. Even if the signal is processed 100% perfectly (which it wont be) it won't 'improve' the sound. If it changes the sound then it's colouring it or cleaning it up artificially which is a bad thing. Without access to a clean source (the DAC) the unit can't do anything positive accept to making the sound louder than the original amp can manage. That's as I understand it but please correct me if I am missing something.eggontoast said:Really, why can't it be improved ?quadpatch said:.................snip................

It's sort of correct. Not all amplifiers are equal, the headphone output of the iPhone is quite limited and only really works best with lower impedance headphones. Even then it's mediocre. An external amplifier, if designed well, will have enough oomf to drive any load to ear bleeding levels. Your point above would sort of be correct if you were feeding the external amplifier from the headphone output of the iPhone, but one would usually feed it from an LOD. This is a line level output which would be driven from an op-amp straight from the DAC, hence it is missing out the inferior headphone and other associated circuits of the iPhone. Think of it as changing the amplifier in you Hi-Fi.quadpatch said:As I understand it the external amp will only be amplifying the signal from another amplifier.

😉quadpatch said:I see what you mean, I stand corrected. It would be similar to changing the amp connected to a CD player.
OK it may have been a bit harsh.......lets say they are better than they used to be 🙂MajorFubar said:I don't think the headphone output on an iPhone so bad to call it mediocre.
