iBasso DX100

[Black_Wolf]

Cyd07: c'est pas non plus le même Dac que le studio, hein, le DAC 9018 de chez Sabre implanté par Ibasso est un engin de guerre.

Sinon...moui, même placement produit que le Hifiman 801, quoi. Je ne doute pas du fait qu'il sonnera sûrement très bien...mais bon, trop court pour moi en autonomie. (outre le prix très conséquent)

7 heures ! Suis je entrain d'alluciner.

Sa vaut le coup de mettre un ecran plasma avec !

[Black_Wolf]

bah d'un autre côté, le Hifiman 801 fait pas tellement mieux. C'est plus ou moins kif kif...

[davidsylvian38]

Pour en rajouter une couche 2 jrs que je me balade avec Studio V + AMP911, et bien promis HM801 alone plus envie !
Mais une fois de plus pas d'emballement rappelons que l'on évoque des produits qui sont pour l'heure des prototypes, et ce n'est pas des membres de Headfi qui sont aux manettes de Ibasso...

Ouais en même temps tu dépasses le budget du 801 là aussi ! Et niveau autonomie le studio V c'est très bon, mais le 911 ?

Je suis en train de me dire qu'en fait on est sur le même problème que les smartphones. La technologie avance, et à ce qui se dit un Studio V ou 801 sont des tueries niveau son tout en étant portables (à peu près), par contre les technologies de batteries ne suivent pas. Sur les portables c'est pareil, des supers écrans des processeurs dignes de star Trek et...des batteries minables qui font qu'on tient un jour, et encore sans trop tirer sur l'appareil. Vivement qu'une technologie vraiment efficace et pas trop chère à intégrer arrive sur le marché pour tous ces gadgets !

Hé les gars mettre des piles à hydrogène ds les baladeurs c'est pas encore pour tout de suite, donc il faut se contenter de la techno actuelle ! Par contre un travail colossal est fait actuellement pour réduire la consommation des composants... Je travaille chez l'un des acteurs du sujet depuis 10 ans et on n'imagine pas la puissance des travaux !

@cyd : difficile de comparer le studio et le 801 autrement que sur la partie sonore => le Studio-V est plutôt réduit dans ses dimensions, et fait sensiblement la taille d'un paquet de 100 tic-tacs ; d'autre part il assure entre 50 et 80h d'autonomie facile ;)

C'est pas le firmware qui doit user la batterie
Purée, c'était trop facile

Bah je prefere des commande facon URSS qu'une autonomie de 7 heures.

Bon premier test de la bete.

Par contre le testeur ne m'a pas vraiment l'air objectif; mais bon ça vaut ce que ça vaut.

Because of the lengthy review, I'll be brief and only highlight the part I thought people will like to hear.

"Testing-Part I:



DX100 uses Android os version 2.3.1, internal version is 2.6.32.27....basic operation is smooth, opening web pages and changing sound tracks did not result in any hesitation. DX100 has its own music player, as such, using the Android's own volume control while playing music has no effect. Inside the Ibasso dedicated music player, one can upsampling or downsampling or choose specific sampling rate. One thing needs to remind everyone which is this particular version of os, according to Old Fellow, has unique or dedicated linkage or shakhand with the dedicated music player, so if anyone attempts to upgrade or downgrade from this version of OS may result in operation difficulty of the entire system. DX100's 6.3 and 3.5 headphone out has the same output. However, volume control is a little different. Volume control from 0 to 140 steps is finer, whereas between steps 140-220, the steps are equal, and from 220-255, the individual steps have more volume increase. Battery life was fully charged at 4:30 PM and has been in use until now which is 1:30 am with one bar remaining. I expect may be it can run for another hour.



Testing-Part II:



Turn on and turn off, and when volume is at max 255, there is some noise that can be heard clearly. ES3 normal volume setting is 155. When music is playing the screen will automatically turn off without any noice.



Floor noise or background noise: under low volume and not playing music condition, there is absent of any noise throughout the sound spectrum. At mid volume level and thoughout the sound spectrum, you barely can hear any noise. At high volume you can very slightly hear some noise. Due to the sensitivity of the ES3 at 126db, 16ohm, normally only low level of volume is needed and at this level there is no background noise noted.



Noise in changing track, and or during pausing: when changing sound tracks or pausing, there is a very slight "ka ta" sound. Starting Wifi while music is playing will have some sligh noise. Surfing web pages while playing music produces no noise. When playing music and surfing web pages, changing web pages and turning on and off the screen produces no noise at all. Later, changing to ED 10, C5, and D500 the lower sensitive phones did not produce any noise. Changing volume level while music is playing produces no noise whatsoever."



Part 3 is coming next

Continuing...



"Testing Part III:



Direct Driving; Headphone and Iems.

Testing Equipments: ED10, B&W C5, and ES3



Vocal:



Track I:(Ayaka) Why-PSP, Wave-Japanese version-Clap and Love

Track 2: Beautiful World-EVA, Trails APE



B&W C5: The uniqueness of the C5 is the relatively slow speed. I can only barely accept the low frequency feel. So the key is to increase the speed so the bass frequency doesn't sound sluggish or aggressive. Driving the C5 using the lowest volume range, the first impression is that the vocal portion appears rather smooth and full, and comparing to the instrumental portion also becomes rather natural. After several auditions, personally I rather prefer playing the C5 at the mid volume level. At this level the dynamics of the low frequency performs the best, with sufficient headroom. The feeling of details and layering are also more clear. The entire musical presentation is maintained in a relatively natural realm. Comparing to the IPC+Stepdance combo, the DX100 is much easier listening without fatigue. It also actuate and manifest the unique property of the C5. I like this sound.



ED10: One of the two tops headphones. It is the classic examples of easy to drive and difficult to drive well. Those prefer the sound of ED10 will love the sound and those hate it will hate it. Personally it is the most difficult to drive headphone in my present repertoire. Strong point: rich in details, the sound of the piano can cause people unable to quit listening. Sound is very transparent, high instrumental separation. Comparing to IPC+Stepdance, the mid range is very musical. Weaknesses: Treble is bright causing the entire sound presentation to be somewhat aggressive. I personally do not like the style of treatment of vocal by this phone.



ES3: The king of pop female vocal. My version of this ES3 comes with the Piccolino recable. The uniqueness of this cable rest with the rather smooth and rounded treble, mid range is particularly musical, but driving the bass range is more difficult. When the ES3/piccolino is being driven by the DX100, it maintains the typical rounded spherical sound stage. The sound is warm without the loss of clarity and transparency. Rich in details. Comparing to IPC+Stepdance combo, there is a perfect feel of bass range and sense of realism. The position of the mid range and the emotional feel has improved quite a bit. In terms of driving low frequency range, besides my desktop setup and the balance operation of my PB2, this is the most

satisfactory setup. Of particularly special is the fact that this is being driven single ended while maintaining its own uniqueness. In terms of direct driving the ES3, the DX100 is completely the best portable DAP that I have heard, bar none.



Instrumental:



Test Track 1: TACET (SACD), the Vacuum tube recording only violin.



ES3: after the brief audition earlier, I didn't change headphone. So listening to this tube only recording violin I was extremely surprised. The sound of the tube recordings is warm, soft, and rounded. All the musical expressions under this system reveals such transparency that it almost borderline realism, being there. The violin body and the vibration of the string and every minute expression are so finely described. The sound of the piano is soft, full and natural but not imposing. The part of the violin is lively with very strong sense of in vivo and being there. There is no part that I can be critical of. I feel there is no need to test any other headphones-but because my friends insisting my testing to continue, so I did. Having a sense of being wrap around by the ES3 and immersed in the warmth of the tube sound, and with the addition of the abundant expression of the violin can easily caused me to forget what phone I am listening to. So after being loss for half an hour I finally continue my testing.



C5: I became somewhat uncomfortable after switching to the C5. This is because the spherical sound stage suddenly was enlarged and I lost the familiar sense of being surrounded by the feeling of warmth. The soft and rounded mid range becomes a little dry. The residual effect of the ES3 has lasted till now. The treble of the C5 is not as smooth with a slight touch of brightness. The piano on the side has loss a little liveliness. May be personally I still haven't awaken from the trance produced by the sound of the ES3. Comparatively speaking, if I hadn't heard the ES3/piccolino combo, may be I can listen to the C5 comfortably but I won't have the feel that is bought on by the ES3.



ED10: Still remembering one time I used an HD800 desktop system to listen to the ED10--I almost throw away the ED10--it was too bright and aggressive. "It is like the sound of using a hand saw pulling on steel wire" Under this system, the DX100, that brightness has been managed. It is a big improvement at least I can listen to violin with the DX100 even though it is still bright."

Continuing the last part of Garyvictor first half of his review:



"Test sound track 2: Dvorak Symphony N0.9 in E Minor, Op95, From the new World-Allergo con fuoco, 24-192 Wav.



The real purpose of testing this sound track is to check the ability to decode 24/192 materials. The fact remain that teh DX100 did a very good job in supporting the 24/192 format. The only exception happens during very busy passages, there is some sign that the processing may become overwhelm a little bit. It is manifested by the music having a 0.2 second of gap. But I think this problem should be fixed in a later release. (Hahaha, congratulation to the early adoptors;-) However, Again, after burn-in, this problem may go away though. lets keep an eye on it).



ED10: The resolution ability is very good. On certain drum decaying almost matching the HD800. The entire presentation is still lacking that of the 800. The string scratching feel of the double bass is very good. Here the treble is not as bright as previously experienced. On the whole, the treble, mid range and bass range is more balanced. Finally the ED10 has the posturing of being tamed."



Well, that is it. I am sorry for the lack of proficiency in either languages. Hope every one can get the gist of it.

Le prix et l'autonomie cassent le rêve !

[Bigtonio]

Oui puis visiblement ils ont tellement mis une surcouche sur l'OS que tu peux dire by by aux upgrades sur cet android.
ça a l'air un produit vraiment curieux ce petit-gros machin.
On sent pas le testeur uber WWWWaaaaawww non plus.
