"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."
