Ibasso D10 Cobra
need updates on it!!!
oh yeah...beck to Audiophile...stopped for a while to avoid more poison when the battle of W3 and IE8 was hot...

no need ler i in kl rite now
wan me to poison u somemore with my iqube? somemore super caps now i got.....

LMAO...no need la...got Cobra?

I think he's more interested in the DAC than the amp

ahahaa...you still remember huh...yeah...my main interest is because of the DAC...was amazed by the modded ibasso D1 dac...

did yuheng called you up?? That time you asked him to find a iBasso D1 for you right?? Well iBasso no longer produce it. And since the original buyer of my D1 bailed out. You can have mine instead

wanna test Cobra 1st lol...how much are you letting go the D1?

Where to buy iBasso D10 in Malaysia?
If I order it online, is there import duty impossed?

well any review bahathir?

Don't spam lah paca.

Tis isnt /k/

Ok..
but we need a review from a fellow forumer

First thing first.
I do need a decent DAC/AMP, because my Thinkpad T61 soundcard is not quite good to drive my PFEs. I need more power and SQ too. So I decided to by the D10, based on reviews from head-fi gurus. The price is quite reasonable and the main feature which I like is the 'SPDIF optical/coax' Digital input, where I can use it with my cheap DVD player and my desktop PC's optical out.

The sound.
1) Generally, this amp is a WARM amp, where you may find it's bass and treble are boosted a little.
2) I read somewhere, that iBasso create the amp based on ER4 as a reference. I might be wrong.
3) This warm sound do match very well with PFEs
4) With PFEs, it sound more fuller and cleaner
5) The detail or resolution is superb, magnificent. No DAP can challenge this yet
6) The high, is sparkling and detailed
7) Due to the warm sound signature, you may find it, much BIGGER soundstage. Or, you may find it you are listening a bit back from the front row. With UM3X, it is definitely an awesome 3D imaging. Very good for classical and jazz.
8) The main thing is the POWER to drive PFEs. I found it, the sound signature changes accordingly with the volume level. Even with the high volume level, it is still very nice and easy to your ears, compared to the 'LOUD' sound from full volume of the Touch 2G. But,please don't do this often

Cons .
1) It picks up GSM noise excellently .
2) With UM3X, you can hear hissing (when connected with USB) or hum when I touch the volume knob. Wow, UM3X is very sensitive.

Overall it is a very good performance DAC/AMP.

BTW, I never tried the analog line line (amp mode) yet. So no comment.

Thank you

so im guessing that u use straight from a 3.5" jack?

I expect nothing less than the headphoneaddict student himself
+1 point for ypu..

great sound stage for classical and jazz?

too bad its sensitive with the UM3X how does it goes with W3 i wonder...

Yup, directly from D10's headphone jack. Also I am not rich to get Predator, Pico, P51, SR-71a ... just to amp the other amp

Ehem, yup. I think Headphoneaddict (HPA) listening taste is similar to mine, might be because of age

Yup, the UM3X is very sensitive, but once the music flows.... no noise can stop it he heh he he. The classical, do sound more realistic with UM3X. BTW, you can op-amp rolling the D10 to get different sound signature... which I don't have time yet to try out.

get a optical/toslink glass cable like my older bro..
he said people like you guys are analytical listeners..dont let the interconnect became yours weakest link


d10 and yet way too humble..

Yes, I know that ... FYI, I started listening via full digital link since 20 years ago ... But, I really lwant to enjoy my listening without being to fussy or too demanding So, a little noise ... not 'hal' lah... For accurate listening, PFEs is the best to my ears .

W3 Sensitivity: 107 dB SPL Frequency response: 20 Hz -18 kHz Impedance: 30 ohms

Um3x Sensitivity: 124dB/mW. Frequency response: 20 Hz -18 kHz. Impedance: 56 ohms

i thought higher impedance lesser hiss?

Ala ... don't be so formal lah.... Just treat me, as your close friend. I am still learning ...
I registered on headwize.com BEFORE head-fi.org

But, even with higher impedance, the sensitivity is still 124 dB/mW@1kHz. So,refer dB/mW the sensitivity, not the impedance.

Ye la... W3's sensitvity is 107dB/mW@1kHx.. similar to PFEs... but, PFEs sound 'thin' without amp, but W3 are much more fuller, because of 3 drivers.

really?
then why people use a 75 ohm resistor to kill the hiss?

Pardon me. i don't mean to intrude but i'm rather curious.

I see there are threads about D2 and D10. But there's seem no serious talks about T4.

I guess it is really not that popular huh?

T4 i think is way overpriced
but the d10 however comes with optical..

is optical is the same as spdif?

SPDIF = Sony Phillips Digital Interface, is a digital Protocol. Optical / coax is a MEDIUM. Both are diferent things, because with optical medium, you can carry different type of protocol such as, Ethernet, Fiber channel,... . If we said optical in audio, it is referes to SPDIF data format with TOSLINK connection using fiber optic medium . SPDIF also can be carried using cable which normally we called COAX.

Reference
http://en.wikipedia.org/wiki/TOSLINK

ok heres the probs come in..
when at my uni..
im using acer 5920g laptop..
it said that it support spdif..
do i need a spdif converter or what??
or i should buy one and try to connect it.
if cant then i go buy the usb adapter?

No problem with it.. It support SPDIF data format... but which type of medium? cable or optical? If the optical use the standard TOSLINK, than no converter needed. If it use the standard RCA, than normal audio RCA cable is enough. D10 has both type of SPDIF interface type.

TQ.

you?
you in usm also?+a female
in audio
i not lonely anymore
lol..
i jus received email that my headphone is SPDIF supported..so buy a toslink cable then changed it to 3.5mm..

Why? you think female cannot be an audiophile kah ? he heh he he...

Care to tell us, what headphone is that?

senn hd600..
i need a cable+amp..
the headput jack not enuff juice

can ngorat also

Wow, your taste is very high . Congratulation.... I only tried my friend's Senn 595, and if you likes the Senn sound signature, than you may like PFE too

Errr... actually I knew her . AND... I mistakenly/accidentally posted the message with her ID hhe heh he he .. sorry for the confusion... he heh he he... But, you may still have chance to 'ngorat' her, ... but .....

ok ok ok .. Back to topic ... Wait.. what amp are you using ?


The cable is just simple 3.5 mm mini jack to standard RCA. You can DIY it for less than RM10.

what a small world
lawa x?wakakak~
i alreadi had a gf and i love her with all my heart

me DIY?
me damn low skill.very low..
bahathir..
you work in this type of field rite..
can do a cable for me?

im looking for glass toslink but 1 end must be made 3.5mm jack..can?
do this 1 for me n 1 for u also

paca...
to use the spdif port on ur laptop...
u need a mini-toslink adapter...
it looks like a 3.5 jack but for optical signal...
and that little piece of crap is damn hard to find!

good luck finding for mini-toslink to toslink cable man...

you know about this??????
help me pls

mini to jack toslink adaptor...those i think u need to search around maybe in Giant, Tesco or audio electric shop may have.....
i think u better ask pcwork to diy u a cable for hd600 since he got some cardas connectors which is very good for senheisser...rhodium plated plugs...
makes senheiiser more faster, detail and less veilly....


Attached thumbnail(s)

cardas connector?
but it is still a mini-toslink rite?
or not?

Make it simple.
Your laptop has SPDIF in mini jack format. Your amp has spdif RCA or TOSLINK (optical) ?
If your amp only has TOSLINK interface so ... use the minijack -> TOSLINK interface la,,

at the moment using zero..
but if go back i cant bring the amp cuz its not mine..
how?
buy d10?

nope ler cardas connector is for senheisser cable ler if u r planning to recable yur hd600...
the pic up there is wat u need to get ... the mini jack to toslink...

recabling?
how much it going to ketok me?

ask pcwork to quote u the price hehe

sep,,can give the the green light on this product?
or i should go for philips/monster?

1 noob question here: what's DAC? what does DAC do? usually headphone line out no need DAC right?

1.DAC stands for digital analog converter..
2.it coverts digital data to analog
3.no because h/out is from internal SQ not directly from source

Here is a simple explanation about DAC.

Source -> (Digital Data) -> DAC -> (Analog Signal)-> AMP -> Headphones

1) All digital players MUST have DAC.
2) DAC performance varies due to cost saving and size.

So, a separate DAC/AMP do sound better due to better power supply, better electronic design (less noise, high dynamic range) and better components quality. Sometime you can hear hiss noise, distorted or underpowered sound with standard mp3 player or laptop. But with external DAC and AMP, you may get a better sound detail (resolution), more bass umph!!, and deeper bass and more extended treble. You will notice all these with a good ear/headphones.

TQ

bahathir..
ur daughter what school?
in usm

I think you got the wrong person, because, she just received the offer letter from USM

Back to topic.
Currently "In Nirvana", listening Diana Krall's album "From This Moment On" with UM3X and D10.. Wow... after 2 weeks, my brain already burn-in with it's sound signature. Now I can appreciate how good are this combinations.

Bass: Wonderful. Secukup rasa. Just nice
Mids/Vocal : No need to say more... Lush... also 'Secukup Rasa'. No exaggeration.
Treble: Eventhough much less sparkle than PFEs, but, it's sound natural. No problem, my brain can adjust it

Overall : Beautiful and well balanced sound.

Hi guys,
It seems dat this thread has been abandoned quite long...

I juz got my unit last saturday and i got a question. Here's the story:

After using it 4 a few days with my laptop as Dac/Amp combo and my DAP as an amp. I noticed dat as Dac/Amp i will set the volume knob around
9-11 o'clock 2 get my preferable listening volume but when i use it as an amp for my DAP i need 2 turn the volume knob around 1-3 o'clock, the volume on the DAP was set on 20 ( when listening with my DAP without amp the volume r usually set around 17-25 )

Is this normal? or my unit r faulty? hope somebody can clarify on this...

sorry if my english was bad... Thank you

It is normal...
This is because the DAC in ur DAP is no as power as the DAC in the Dac/Amp combo..
**the voltage/current output smaller than the DAC in the combo...

9-11 oclock @ DAC mode is normal. Eventhough D10 is the headphones amp, but, it is not as powerful as desktop amp, or the silver amp (as jkleekc mentoned). Yes, everything is about voltage and current. You can try few opamps/buffer combinatons to get more output power.

thx 4 the replies there guyz... really helped 2 clarify this...
i haven't opened the unit yet coz still busy will try the other opamps provided this coming holiday... yeah i've read that different opamps got slight variations in terms of power besides the sound sig...

how to ground myself while rolling the opamps?
afraid that i will fry the chips

sorry for bringing up an old thread
