Hey ClieOS, 

 

Sorry if these are stupid questions. Will wall chargers that plug into a USB work for non computer charging? Either way, will I be able to charge the E12 if I plug it into my laptop? Or do I need a separate "step up circuit" (not sure what that is) to charge from my laptop? 

 

Thanks!

That first moment the amp turns on, the pop is like a SS amp on high gain with the volume turned very high going POP! for a moment. Bad for your hearing, and as the other have said, could "pop" out your headphones too. Though SS amps generally are more predictable, that moment where everything becomes active at once when you turn it on is still dangerous.

Many people don't know that, so the delay Feiao mentioned that was built-in to the E12 is a nice safety feature that should help 99% of the time... but still it's better to be safe than sorry, and just plug in your headphones after turning your amp on.

ClieOS' avatar is pretty cool, I like the choice for it's symbolism: the machine with a soul. You can imagine how that relates to audio gear and music wink.gif
I personally thought the TV show was "Ghost in the Shell: Lite" compared to the first movie. The little blue guys don't appear in the movie, but the concepts are more mature and characters IMO more interesting. I didn't like the second movie too much though, I thought there were too many disjointed and overly complex scenes, as if the director was grasping to express a challenging idea but didn't know how to express it clearly. The first Ghost in the Shell, Akira, Neon Genesis Evangalion, Princess Mononoke, Spirited Away, and a few others were/are my favorite Animes before I moved on to other hobbies.

Boweii, under what conditions do you hear those whine noises? I'll see if I can reproduce them with my gear, but I suspect you are just hearing amplified background noise from other components before the Mont Blanc. To be honest I haven't even needed to try high gain yet biggrin.gif

Apothecary,
I could not detect a difference between bass boost on or off, unless a really low bass note hit, and then the effect was just a bit more presence for that bass note. And I think that's perfect, I feel like the boost is "safe" to leave on with almost any song. It doesn't change vocals or acoustic guitar, and even with bass-heavy dubstep and trip-hop tracks the bass doesn't clip levels and distort. I would like to watch the movie Inception with the bass boost on, that'll be fun smily_headphones1.gif

And Clieos explained it. I had tested with nothing connected with E12 except headphone and charger, and then with various things plugged in.

I think he said that he choose tachikoma because he just liked it?

Yes, the add says it will charge from both 1A/h and 2 A/h chargers.  It should charge from all laptops, car and wall chargers.

Actually non-PC / USB adapter is recommended for recharging E12 - in fact, you should get a high power rating USB adapter since E12 is a bit power hunger when it comes to recharging. As fiiO has suggested in the manual, 2A output (which is what USB 2.0 can output in max) works the best. Most USB port on PC only go from 500mA to 1A. Some even go only up to 250mA, which will take a longer time for you to fully recharge the E12. Many laptop actually only supply 500mA max, or have different rating on different USB port. You can still use them, but it will take longer. Even a 2A charger will need 2+ hours to fully charge a E12.

 

In short, any USB port (PC or USB adapter) can charge E12, but it will be faster if it is on higher output USB port.

Slow charge= healthier battery in long run

fast charge=not as health.

Correct Panda Battery Procedure:

When the device is in use, do not use USB charge. Turn it off. When the E17/E07K is on it's final bar of battery, turn USB charge(or the USB cable) on and charge it to full. And then unplug or turn off USB charge and use until you are on your last bar of battery left. When you see the bars reduce to one, it would be best to start charging(sometimes you are out, and you can't, that's understandable, a few times won't hurt). Li-ion batteries like the one's found the in the FiiO E17 Alpen's don't react well to a full cycle of charge and FULLY de charge until the battery is dead. This has been proven to be actually bad to the life of li-ioin batteries. HOWEVER., you should do a full cycle where you fully charge up the device and use it all the way until the device automatically turns off ONCE every month or two as that has been shown to actually be good for the battery WHETHER you use it constantly or not. Do not fear my friend, even if USB charge is turned off when the device "dies" it will still charge after it runs out of power naturally as the E17/E07K's firmware will reset!

 

Li-ION batteris on general will last effectively 1000 complete charges before battery drops below about ~70% of the original storage. This is still acceptable by most consumers standards.

 

20 hours full battery life * 1000 effective uses =20,000 hours / 24 hours a day = 833 days theoretically before the E07K under theoretical conditions will decrease to 70% of its original storage life and this is with a full depletion and then charge cycle. And that is 24 hour usage as well.

 

FiiO currently reports that they will send replacement parts for a very low price. The battery is not that hard to user replace(but not under warranty). 

 

Partial charges for Li-ION's are better but of course constantly doing partial ones has also been reported to have an effect on the device as well which is why I recommend to charge before all power is gone and to charge till full.

 

The last point to make is that you can't use a device if you keep on babying it. Using a device and enjoying it is part of that batteries intent and life cycle. Honeslty, ANYTHING you do to it will have an effect on battery life. The majority of the time, it is a minute effect to something like an audio device. (This advice does not hold for Power Wheels, those buggers need proper battery handling). Enjoy the device, theoretically it will hold up well for many years.

Disclaimer: I am not an expert on batteries. I am self taught. Please correct me if something is wrong. But use sources and not just something your papa or person told you to always do.

 

 

 

But hey. Do you buy a car and keep it in a garage for the rest of its life? 

 

No. You use that thing. Whatever suits your life style  I use the instructions as it's not that hard to do but some just don't remember. And that's fine.

Yes. As a member of the anime thread on head-fi. I must know the reasons. Especially because Tachikoma is my favorite supporting character/character in general of Ghost in the Shell.

No. I said that. I just added more info.

 

I'm not an expert. But I have done much reading on li-ion batteries. And it said that generally a slow charge will lead to an overal healthier battery than a fast charge for li-ions. However my rebuttal is that if you always use a product and keep it safe, you won't be able to enjoy it. tongue.gif

 

Correct me if I'm wrong. This is just what I have got from reading around on sources and etc.

Very well! Sound quality is much improved, and the power is definitely there for my HD650's (so I don't have to crank the volume up all the way). With the amp on max output, I can get a volume about equivalent to 25 unamped at just 15 with the amp. That's pretty loud, though, comparable to about 18 unamped for my Grado SR-80i's (should be about the similar to your Alessandros). For more comfortable and extended listening, you don't even have to turn it up that high.

Haha I was wondering if anyone would notice. I can use them to change the crossfeed and gain, right?

Who cares about the battery. By the time it goes there will be the E13 out biggrin.gif

The links didn't work for me, I have read on XDA developers (useful forum, bad layout) that you must charge your batteries (lithium) as many times as you can. I don't know for sure, but I'm about to take a Chemestry course on my Tech Institute (studying EE), so maybe latter I can make a better statement.

Great, thanks that's very useful, gonna wait for that Fiio E19, if not then the E12 it is. Nice Montblanc pens joke tongue.gif

Ask your prof :)

That's some very expensive switch you're using.

It increases soundstage tenfold!

post #720 of 2975

What's the point of crossfeed?  Doesn't that just decrease the soundstage?  Crosstalk is something that's tried to be minimized as much as possible and now here is this function which is intentional.  I don't get it...
