I buy on Amazon, based on reviews here and there. I'm disabled so going out is a problem. But when I was going out, Best Buy. But right now I'm looking for an inexpensive portable amp shielded from my new GSM phone. Any ideas?

Hi slick1ru2,
Thx for your advice, that really help us. 
Before  I decided purchase sth online, I would also read reviews, which seems to be a habit to me. And even if I don't buy it, I read the reviews for knowing others' experiences.
As for the amp, pls kindly tell me your phone type(Android?iPhone? or which brand GSM phone you use?)   So may be I can recommend you one)
Nice day.

Hi  slick1ru2 
 
We actually have not tested any amp for Moto G4, since it is the newest cellphone( good choice)
If convenient, you may try A3, E12,  E12A,and that depends on the headphone of yours.
Best.
 
p.s. all these amps are for reference, since listening experience is subjective~

Well, it's the only one of my 4 past phones to do it. It's the first with 4G LTE so models that shield that well should work. I was told the A3 still has interference with GSM.

Oops, I was told the A1. I'm going to try the A6. Thanks for your help!

  Hey guys,
 
Gonna ask u several questions. Usually where do you buy the headphone/player/amp/dac, online or in physical shop? Which physical shop you prefer? Best Buy ？Frys？Riaoshack ?
 
And is FiiO in your city, if not, would you be troubled without listening practice? Maybe you can recommend a certain physical shop in your city. LOL

I usually fetch my audio gear from amazon... and for a physical store I go to Guitar Center. BUT, Best Buy I'd heartily recommend because they have such a large number of stores, and to get the FIIO name out of the exclusive knowledge of Audio Junkies, I'd start at Best Buy.

Thanks for your support,which helps us a lot.
We will have a try.
Nice day,

I'm reading a lot of reviews on amazon claiming fake A1's are being sold. Is there a trustworthy seller on amazon or eBay for the A1? Or, can we buy direct from Fiio?

Hi, danmlr
If the sellers in Amazon are listed in our authorized sellers' listhttp://fiio.net/en/stores), you can purchase without worrying about the authenticity. It is recommended to buy the product from local seller in order to have more convenient after-sale service. But you can also buy product from our Aliexpress ( https://www.aliexpress.com/store/product/FiiO-A1-Headphone-Amplifier/1473108_32683540739.html )if there are no sellers in your country. Thank you for your support to FiiO and our product.

Why does Fiio A1 sound alot better when plugged in usb power? Im using battery 5v power, and there is still some noise present from powering it this way. High frequencies sound cleaner & thick and sound image has more depth. Amplifier sounds unstable and a bit weak on battery power only.

So I have a question. I'm thinking of getting this to connect to the RCA line outputs from an amp, so I would have an additional headphone out, plus me or others being able to listen to headphones loud while the rest are listening to the same sound through speakers on moderate to low volumes. (didn't know how handy that can be before I tried)
 
I know, you're thinking I'm gonna ask about the cable. Sorry, already have the cable I would need.
 
My question actually concerns connecting something like this portable headphone amp's mini jack, meant to connect to another mini jack on a smartphone and the like, to the RCA line outputs meant to connect to, well, RCA line inputs. I noticed already while using a computer speaker for such purpose that the RCA line output is quite a bit louder than the one from my Macbook set at full output volume. Is there a possibility of that negatively affecting sound quality, or being damaging to the unit?
 
Cause this little thing looks really nice, and I particularly like that the input and output ports are at opposite sides, as well as the price compared to the quality I hear about. There's also not much in the way of desktop pure analog amps that I find attractive, and they're all intended for high impedance headphones which I don't plan to buy.
 
If it matters the headphones I will be using are Koss PortaPro and Senn PX 100-II.
 
Thanks for reading, and for answering if you so please.

When the input voltage is beyond what the amp can handle, it can cause distortion on the amp's output, otherwise known as clipping. It however usually won't damage the amp itself. According to FiiO, A1 can handle up to 1.35Vrms ( = 3.81Vpp) - if your RCA's output is over that, then A1 won't work.

Thanks, that explained a lot. Checked out on the Fiio page, the spec seems to be called either Max input level or Overload level. (I guess those are the same?) It's alright for the Fiio A1 then, but I think I will be going for the A3 after I calculated the shipping charges on Amazon. (A1 only a 1/3 cheaper when shipping is included, since there's a seller with a low shipping rate for the A3 to my location). It's for a HiFi setup use after all.
 
A3 clips at a whooping 8 Vrms.
 
Merry Christmas.

Product Review Of FiiO Products---From James

Chapter Six: A1

We have finished all the products in 2015. Today we are going to embark on a new journey. Let's move to the product story in 2016.

The A1 is a mini portable headphone amplifier. When it comes to the ancestors of it, we could not miss FiiO's first headphone amplifier, E3. In fact, it should be traced back to the time sequence of E3-E5-E6-A1. The reason why we did not continue the name with the first letter as E is because it caused name puzzles when more and more products of the E series were born.

Like the E3, E5 and E6, the A1 is a headphone amplifier excluding the decoding function. It is compact, with EQ and a removable transparent back clip. It seems that the E3, E5, E6 and A1 are very simple products, but they all well meet the needs of foreign users who use mobile phones and MP3 with some high-impedance yet low-sensitivity headphones. They can effectively increase the driven capacity, and also help to improve the sound quality. Therefore, in overseas markets such as Europe, America, Japan, they are very popular with users including audiophiles. It is roughly estimated that the global sales of these several models were in a total of millions.

However, the Chinese market is different. Those ordinary users were not interested in such products, while audiophiles prefer better and more expensive products. This is actually an interesting phenomenon.

So in china its in sort of a dead zone. Not worth it for the normal user, not good enough for the enthusiast.
