Also this was my first review on Head-Fi, so if something doesn't make sense or needs elaboration just tell me, 'kay?



Thanks for that. I laughed quite a lot. For a first review, your style is fantastic! Ditto on the jaron and explanations.

When an audiophile is faced with better sound or a slightly longer battery life, I think they will inevitably choose the former over the latter.

Since you're so adamant, I'll do some further high gain listening and get back to you, 'kay? redface.gif

 

Thanks for the feedback, all.



Sure. Just my opinion here so don't take it personal. Low voltage and hi gain. The low gain is more noticable worse in low power, for me, so that may have something to do with the power selection. I actually find low power better for my effecient IEMs so it's not about saving battery for me. Probably just runs the chip at a lower voltage. Should spec out the same except for max level available. AD does most of their measurements with 5v rails. Low power is 4.5. High is 6. The unit should swing almost 9v in low power and almost 12v in high. Audiophile? LOL, I can't find cartridges under $2k. More power doesn't get you anything other than more volume unless you have a load that needs it or it just happens to be better.

 here's a quick Ipod pick of the circuit side.

Changing gain is just changing a resistor value.

I really wish burn-in on solid-state kit WAS all in my head. I absolutely hate reading that people can expect to wait 1200+ hours for the RSA Predator to 'mature' and give its owner everything they paid for.

If so, likely in the feedback loop to effect loop gain via more feedback. Not a fixed volume control. I checked your profile and saw that you're a young man getting into electronics. Think about it. How does 1 resistor pull that off without affecting impedance or feed back. A simple series resistor does little on it's own without being a very large value. If you know how and where in circuit, I'd honestly like to know as I find it interesting in general. If others don't hear it, fine. I'm good and don't really care. I just posted as my results were different than the OPs and last I checked, this is a discussion board. I don't understand how someone can tell others what they can or can't hear. I do understand how 2 folks can hear the same things differently as there are many variables in kit, files and familiarity.

And what, pray tell, is the DIY amp you built for £120?

Not bashing the E11 for its price and form factor, just reminding everyone that it’s not the second coming of Fritz Sennheiser.

Oh lord, I enjoy building amps, not designing them. No real electronics background. I know how to build and debug stuff, but not enough to understand electronic circuits. I have a stack of electronics books on my shelf to remedy this, and I'm going to start reading this week, since I have free time.

A very interesting and informative review.

 

I don't like the RE-ZERO but love the RE-0 and can't wait for my E11 to arrive and try them out. With their higher impedance they should be a better match for the E11 and my ears.

It was a HiFiDIY.net Panda amp. They list the kit alone for $99 but you can get it for cheaper on eBay. I've had it for nearly six months now and I'm very happy with it.

Here's a 48-page thread on RG if you're really interested.

Just took a look. Nicely done. Glad you went with a toriod. Can't be done for that money but a bit more regulation and an active input stage would have been fab. Did you play with the bias or output resistor values. Low should be fine for everything unless you need to lossen up the bass a bit.

I upped the default gain by about 6dB and used 110R output resistors. The amp is already capable of ~2.5W into 32 ohms with no resistors, whereas with 110 you only get a paltry 570mW into 32 ohms (200mW into 300 ohms). That's easily enough for most normal cans, and since I took that picture I've added a low-resistance socket for orthos and for setting the voice coils of cans I don't like on fire.

Sounds like your enjoying the experience. Back to the E11. I'm certain about my impressions, for me. I was playing around last night when taking the photo, which anyone is free ti use, and apparently left it in the high voltage position. Loaded up for a dog walk and immediately heard it was thicker again. Flipping the power switch back down put it back to were I prefer.

Great review Joe, wish more people would write in your style.

 

As a supporter of the ' why the f*** are people using amps where there is absolutley no need with those iem's.' mentality it was refreshing for someone to spell it out. and hopefully save people  a lot of money.

 

I actually use an amp to gain line out functionality from my ipod in doing so iv been happy with the e7.. not so much with the nuforce icon (thin sound?) but at £40 i will probably pick up the e11 for the volume knob alone :)

 

good humoured and all around great review!

I suspect that you are preaching in the wrong pulpit here, Reverend !  rolleyes.gif

 

As far as 'saving people a lot of money', I think Fiio have tapped into something I encountered in another thread recently, and I have to admit that its not something I had considered as one of the 'Top 10 Reasons for Buying a Portable Amp'. 

 

In the middle of a debate about the form factor of a couple of amps I see as 'competitors', I got this:

 

I know I probably dont really need an amp, but they just look so damn cool !

 

I have yet to be approached by a woman who asks: 'Is that a portable amp in your pocket, or are you just glad to have an internet connection so you  can post photos of your portable rig ?'. If I were, I'd ask if she wanted to come back to my place and roll some op-amps.

 

Guys, 'cool' is a '68 Barracuda Notchback with a 340 and the pistol-grip shifter. Post a photo of your 'Cuda cruising Van Nuys and I'll erect a shrine to you in my kitchen, complete with fresh Lotus flowers every morning.

(Hey, the thread title is about 'Loud Things that come in small packages'. In '68, that car WAS a small package)

haha true that,

 

Every time i get a new bit of kit and show my girl she just laughs and says 100/200/300 for that? ...your a f***in idiot lol!

 

Yet for some reason when i bought my all black Supra she goes on about it!

 

 

pffffffffftttttttt whats she know id trade the car for my hje900 any day lol!

 

I agree because it looks cool should be dead last on anybodys reason for buying audio equipment............ although i still do it!
