FiiO E17 "ALPEN" - First Impression + Final Thought - Page 314

If so, I will also be able to bypass the phone's DAC and take advantage of the E17's DAC.

What I am wondering...  I have a set of amplified computer speakers hooked up to the computer's sound card.  When I connect the E17 via USB, does this mean that that sound card will no longer output audio to these speakers?  Or is there a way to connect these speakers to the E17 permanently and still be able to plug in my headphones occasionally, as well as connect it to the phone's dock? 

Thanks

Just a thought......check out the mighty FiiO E09K.
It may be what you are looking for.

So is the E09K and E17 a good combination?  Currently I am using a Audioengine D1 with my MacBook Pro (so it meets my portable needs), but I was looking to get another one so that I don't have to pull the D1 out of my bag to use at home with my Mac Pro.  I am using with Sennheiser HD600 & HD650.

I've never heard the E09K, it just sounds like a good solution to your dilemma!
line out for your speakers, headphone jack, plus you can still use the E17 as a portable DAC/amp.

Just wondering, what will happen if you plug a headphone straight to the L7's line out? Or any line-out of any device? I would be guessing that's a pretty powerful signal and can blast your headphones off? Is it dangerous that you should really be careful not doing it in case you're drunk playing with the audio gears you have? Forgive my ignorance. Thanks!

Line out isn't that loud. It's just a 6dB gain. You an get USB, Aux, and Opt to have the same loudness by adjusting the gain to 6dB in the menu.

Just got my E17 and Q701. Ive only listened to the combo for about 15 minutes so far, but so far i like it. The E17 is plenty powerful, with the 12db gain using my iPhone 4 LOD out, im only listening at the 24-30 mark on the volume control. Im using a 2db bass boost, which is nice to have. I could stand the Q701 with no eq at all, but the 2db boost adds a nice touch of warmth to the sound.

 

One question, did everybodys E17 arrive with a completely dead battery? Mine was completely dead which has me worried. Lithium batteries should never be stored completely discharged, optimaly you want to store lithium batteries at about 70%.

If I recall correctly, FiiO ships out their units charged or at least mostly charged. The E17 has been out for almost a year. On the back of your E17 does it say "E17" or "Alpen"? If it says E17, it is most likely form a shipment that came in almost a year ago. If it says ALPEN, well it could be around the same time frame up to today. The first two months the E17 had the E17 sign on the back, with the Third and Fourth batches as Micca Store called them I BELIEVE (its been a while), the name on the back was silkscreened and changed to "ALPEN". So yeah.

 

My E17 battery guide does say that you shouldn't discharge it. However, battery experts do say that people that use their E17 frequently should discharge it fully and recharge it about once a month and those in storage should do it once every half year. This has been shown to actually be good for a Li-ion battery. But yes, full discharge of li-ion frequently is not recommended at all.

It does say ALPEN on the back. I really dont like the fact that it came dead. Maybe i should contact Fiio or the seller about it.

Because now there is a possibly defective unit that has a battery reduction that isn't possible to calculate or ever be able to tell as the initial battery and its life was not on hand?

 

Unless your unit is acting up in any way shape or form in that it will not take a charge, or turns off and on, wont turn on easy, or the sound has some problems, I do not believe there is any problem to contact FiiO or the seller about. If it is only just your chagrin at the E17 unit comming to you with no charge on it, as in, that being the only problem you have with it, I can't say that you will be able to get a return or what not.

Yea, but like i said, a lithium battery sitting with absolutely zero charge is not good. Ill at least try it for a while, but if my battery seems to drain extremely fast then i will be contacting somebody. I would just hate to have a unit with a bad battery.

I see your point. The majority of cases, it should not be a problem, but if the unit does exhibit problems, well then let us know.

Another question, How long should it take to charge a completely drained E17 with a 1000ma charger?

That is about what most iPhone or phone chargers output. Charge time should be about 5 hours if you are not using it. Charging with USB directly on most laptops can be as much as 8-9 hours with periodic turn ons and offs.

post #4709 of 6578

Im charging it with an iPhone charger, but i have been using it for about half the time its been charging. Its been charging for almost 5 hours, ive used it for probably about 2 hours of that. Good to know, it should be done soon i guess. 

 

This setup sounds real good. Seems like a great little amp. Anybody that says it cant drive a Q701 properly is crazy.

the charge time should be about 3 hours, we are upgrading our website, and I ask our term to release more specification on our website, includes the frequency response and THD test result by AP. the new specification will add some useful information includes

 

1, output impedance,

 

2, battery volume, charge time, battery life 

 

3, maximum input votage

 

4, bass/treble boost value.

 

5, crosstalk

 

6, Gain

 

of course, some spec is just for reference like the battery life because it depend on the source, loader.
