FiiO E9 Review - Page 31

Well for what it's worth, a working unit does not need any wiggling to work correctly.

My replacement unit is very sturdy and durable.

Out of curiosity; where was yours purchased from? As far as I know Micca (or Amazon through Micca) is the only authorized seller in the US (if you are in the US of course) and the defect of your E9 could be a result of mishandling by third party sellers.

All I'm saying is don't jump to blame FiiO when there are several hands that your purchase passes through before it reaches you.

If possible I would recommend returning your unit for a full refund and ordering from Micca. Jack will take good care of you. :)

I am in the UK so although bought from the seller 'Fiio uk' from Amazon, I cannot confirm that they have just used the name 'Fiio uk' or they are a recommended supplier. I am not trying to slam Fiio, as you would read from either this or another forum post, I was already in 2 minds over the Fiio and valve option, the fact that my unit is faulty only strengthens my want, to trying tubes, though I would not be surprised if I get another faulty amp from elsewhere!! I will still jump on the Fiio band wagon when the E11 comes out but I think I will wait till bugs are 'ironed out' till I splash out. It is the same with everything new, things have teething problems and it sometimes takes customers to point out or find out these bugs, for the builders to fix. As I say, I MAY accept a replacement but will need some convincing. You see, the jack crackles a bit of my E7, I initially thought it was my cans but same on my IEM's. Only slightly when moved but still apparent. I have lived with it but now getting a faulty E9 for Xmas is a burden too far ;-)

From FiiO's website; the only official seller that carries the E9 in the UK is mp3amplifier.com.

I'm not saying don't go for tubes; by all means go for what you want!

Just know when it comes to solid state, the E9 has been able to power many flagship headphones such as:

- Beyerdynamic T1

- Sennheiser HD 800

- AKG K1000

This is UNHEARD of for the E9's price tag.

Yeah, I will have to have a think really coz I've had a chance to listen to the little dot mk3 over Xmas and do like the sound of the tubes. I am just not convinced the E7/E9 is for me. I am not really happy with products that need 'wiggling' or messing with to get working. The fact that the E7 isn't a great fit as well as the jack problem just doesn't bestow me with the confidence I want when paying out my hard earned (or the Mrs hard earned). I am still to receive a response from the supplier so will see what they have to say first.

Thanks for your support!

Please contact our agent first! if they can't , we will help you solve the problem! not matter what make it happen! but please give us more detail describe so we can check out what happen before you send it back!

There are some misunderstanding in the past, once our agent return us 15 E5, but he finally realize it is not a defect, but just because people had not removed the file which to protect E7's screen during shipping!

Also I should admit that there do have some defecitve prducts because we sold out so many amp per month! but we will try to improve our QC constantly and solve the problem if it happen!

About the noise happen it potentionmeter when adjusting, that is the main reason we use digital volume in cheaper amp like E1, E5, E7, becuase it is hard to prevent unbalance and the a little noise!

Maybe we should reconsider use digital volume control in the future!

Soon our newest website will launch, so now it is not accurate about our agents,

Our official agent in UK includes UAS ( discdiscount is their reseller), AVshop, The advancedMp3player, Mp3amplifier, also Maplin is selling our E5 in retail chain stores!

I guess you can image that we do selling quantity products in UK ( Maplin maybe is the biggest retail chain stores in UK),

Perfect timing James!

@yomomma1,

As you can see FiiO really cares about their products and your satisfaction; even if you did not buy it from one of their agents! If this alone is not enough convincing for you, I don't know what is!

FiiO UK = MP3Amplifier

Hello James,

I am very happy with the analog pot even though there is slight static during adjustments, I think there is no need to reconsider using digital adjustment, at least in the desktop amp line. I'm not sure if this is the general opinion, but I would suspect so.

I too prefer the Analog volume adjustment. It's SOOOOO much better than Digital volume control, IMHO. The static while adjusting is in no way a dealbreaker. How much in the E9's life are you going to actualy be adjusting the volume? For me, it's maybe 5 seconds a day of 5 hours of use. Seriously, to anyone that would consider the volujme adjustment static a real issue...I am baffled. It in now way affects the SQ once you stop adjusting the volume.

Thanks for the opinion! 

I would however like to know what is causing the interference. I'm not tech savvy when it comes to the guts of my electronics, but if there was a fix to the volume adjustment noise, I'd be more than happy to try it.

The potentionmeter using a rotable metal shrapnel , rotate on the carbon film,  and the carbon on the film, will abrade during rotating, So there will have some very tiny carbon dust between the shrapnel and the carbon film.

As Jack had said, if you rotating it several times, the carbon dust may be cleared! also there are some kind of cleaning agent which can clear the carbon. for example , you can use absolute alcohol. or something like below。

BTW, it is a little hard for me to explain it in english! I guess here must have some electronics engineer who can help me explain the reason more clear!

Based on my experience with guitar tube amps, a "scratchy pot" is due to imperfections or dirt on the surface of the resistive tracks. As the pot wiper (usually copper) glides across the surface, the imperfections or dirt causes the wiper to produce the scratchy noise sound. There are cleaners made specifically for cleaning pots just for this reason, but I don't think the E9's pot can be cleaned in this way. I am just guessing, though.

Yes, that is what I try to said, LOL! I guess few can understand what I want to describe!

Like right now, I can't get the noise static no matter what I do... it's so sporadic and random...
