Fiio E9 - any benefit from a better power supply ?

post #1 of 5
Thread Starter 

Hi Everyone biggrin.gif
I have just powered on my new FiiO E9

I have some questions for people knowing it

1)  does it need a long break-in ? confused.gif

2)  could it benefit from a better power supply ? It comes with a switching PS ... I do not hear any particular noise actually, but I also know that linear  PS are usually quieter than switching PS rolleyes.gif

 

Presently I am using it with a sennheiser hd 201 at my parents' home, but next Sunday I will connect it to my also new Beyerdynamic dt990 pro (250 ohm)

Ok .... it is really too early.

But my very intention is to keep the dt990 pro for quite a long time (my first impression has been very positive ... it's my first high impedance HP) and so I would like to find a very good way to drive them properly.

So just out curiosity what could be a surely better amp and at which cost ?

Thank you very much for any kind suggestion

 

Kind regards,

gino

Only if your power supply is defective.

Thank you so much for your kind and valuable reply.

No no ... it is fine, and even with the volume knob at maximum with the input open (no cable connected) the noise is zero.

Do you think that a step-up would be very expensive ?

I would like an expansive sound that could contribute to give a nice sense of ambience (i.e. less of that "sound in the head" sensation).

But I do not know if this very fascinating quality is more related to the headphones or to the amp used to drive them (may be both ?).

As I said I am going to use it to drive the dt990 250 ohm in the end

Kind regards,

gino

The lack of noise is just what you want. Obviously.

 

I don't know the E9 or the prices of A/C-D/C adapters. However, the jack pictured in the photos on Fiio's website say "15V DC." Try looking around to see what they might cost.

 

For questions about how headphone and amp pairings may affect sound, I agree with lorriman's posts in the "O2 AMP + ODAC" thread here at Head-Fi. In particular, Post #39 -- sorry, I don't know how to create a direct hyperlink to it -- talks about your concerns. I recommend, if you have the time, to read the first 3 to 5 pages, or more, of the thread. In addition, nwavguy's web site has similar technical articles. NOTE: Their position (and mine) is "objectivist". Not everyone subscribes to that approach. I also believe that listening tests are critical.

 

I have the (32 Ohm) DT 990 Premium. I received a Fiio E5 yesterday, but I haven't brought the Beyers home for listening test ... yet.

Thank you very much again

You are right. 15 V is the supply voltage.  But the standard PS is indeed quite silent.  I will wait for a complete break-in.

I go directly to the thread you mention.  I understand that it is not an easy task to get a nice diffuse out of head sound.

Thank you very much again

Kind regards,
