AD1852, OPA2604, basically Zhaolu AD, but Zhaolu has better approach at selecting components. Plus, the circuit is almost identical to the basic DAC circuit that is even apllied to Zhaolu, cept the dac buffer/pre-amp stage consist of only one opamp rather than two, meaning signal is non-balanced (zhaolu 2.5 and higher model do not haf balanced output but aminot mod would enable balanced).

Headphone out is also a simple buffered class-b output, almost similar..but then agian, everything is very similar in the audio electronic world.

The cache factor would be the price..but i bought a Zhaolu D2.5A (keep in mind, ac in-line filter, better regulation and board design, all capacitors are branded boutique capacitors, implementation is much better) at..- EDIT : I din know a bulk is on, so I wont bother -
*
Yup. basically it's a Zhaolu AD but coming with fuller and warmer sound, that's what the designer told me, before this he did working in designing the Zhaolu and now he decided to establish his own company. IMHO the ZERO is kinda a dac with lots of upgrade possibility as the Zhaolu, but since the Zhaolu 3.0 coming out, the company decided to discontinue the Zhaolu 2.x series, so people who did consider getting the Zhaolu 2.x and i wish that they may consider giving chance to this potential unit. Thanks smile.gif

Below is the comment from head-fi.org. This clears the doubt of what the noob like me keep asking the same question all over the net.

" basically DAC performs in analogy to a good player dac circuit like that in marantz CD 6000. In turn, u can couple the DAC with dvd player having optical out/with computer optical. In this way, u dont have to buy a quality cd player and dvd player. " dunno if my assumption is correct.

--------------------------------------------------

As a DAC itself, comparing the Zero DAC with the internal DAC of the Marantz CD6000 OSE, I see they have different personalities. The Marantz is more crispy and more "in front" sound, while the Zero DAC is more relaxed and "analogic", but without losing much in details. After few months, I must admit I prefer the Zero DAC, more relax and charm, expecially with classical music and jazz!
With the pre-amp stage on, I see the sound is not impacted, I mean either in bad or in good. As headphone, it provides power, control and soundstage to my Sessheiser without any hint of noise, but I cannot make any significant review here (I don't have any dedicated headamp to compare with).

http://www.head-fi.org/forums/f5/review-ze...58/index71.html

IMHO, I always think that it's good to opt for external DAC instead of soundcard, it provides more flexibility from time to time, no matter you are integrating the DAC into HTPC or doing proper hifi setup smile.gif

the Zero looks very nice Maddude esp. for the very low cost. looks like a great value to me. me thinks Empire Dudes rite in that it can do with some mods. all these products stand a very good chance of improvements even with simple mods like caps changes.

i'd mite be interested in a meet up (if our schedules coincide) with the Zero vs DAH1 as i can also bring my super mod iBasso D1. i did a whole buncha parts replacement + a power supply upgrade the other day and its a pretty stonking change....& i havent even done any opamp changes yet!

think about it - Zero vs DAH1 vs D1!

we'll see which is the ZERO & which is the HERO!!! lol....

ps:for the guyz thats been looking at DAC chip specs, let me reiterate that the "HERO" WONT be down to the superior DAC chip specs but the IMPLEMENTATION of said chip and the entire DAC unit. theres plenty of old NOS philips TD1541s and TI PCM1704 R2R based DACs that kicks asss. witness the much admired & venerated Wavelength DAC series all of which utilize old DAC chipsets.

back to the old adage guys - IT AINT WHAT U GOT - ITS HOW U USE IT nod.gif  laugh.gif icon_rolleyes.gif
*
Wow, ZERO vs DAH1 VS D1 ... If the Zero could achieve up to 80% of the DAH1, I would be so glad tongue.gif

You can arrange some meet probably during your MC, although it's abit annoying for cant speaking comfortably, anyway it's a audiophile meeting what, listening do likely more in action!

For those who are bothering about no SPDIF connection available from you computer, I may help you guys getting USB to SPDIF signal converter like below, so it works like getting signal from your USB port and through that device, after that the signal will be convert into SPDIF signal and send to the ZERO dac. TATTa ~~~ There your ZERO dac would start singing! And this useful little device would only cost you guys RM20.

Nope, it connects your USB cable to this device and then convert the USB signal into SPDIF. So this is for those got DAC which accepts SPDIF digital input but unfortunately the computer got no SPDIF output.

if u can manage to get this device, pls collecte order at bulk, if im not mistaken, i can point out at least 3 person who are looking for this tongue.gif

need a better source now but the size of this thing is drawing me back sad.gif
should i go for it?

Hi there, personally i don't think that the size is kinda big, 240mm(length)220mm(width)55mm(height), it's roughly the size of A4 paper, heck the A4 paper when place horizontal, the paper's width is even greater the DAC width.

One thing for sure, the sound quality certainly hard to beat at this price, mADman has been giving rave review about this unit! and one thing good is, if you wanna put your name into the list, we could straight kick start the bulk! Waiting is kinda killing for audiophile, I know, know it very much cool2.gif

I just found out my dvd player has got both optical digital and analog out. so should be able to support the DAC, but I am not sure if the DAC will match to my tube amp soundstage 1.5 se?

If you read the head-fi thread, you will keep finding good review about zero DAC, catching up with the iBasso head amp.
*
hi there, if you found those two white and red socket behind your tube amp, that's means it's 100% suitable. Those two we call them as RCA smile.gif

Just browsed through the thread in headfi (only around half of the 1xx pages) about this zero and it seems like there's only the same few person giving opinion on how good it is in all the pages and the comparison that made also limited to the few thing the few person owned. Anyway looks forward for more reviews from the buyers here.
*
Hi there, I have seen headfier comparing this to Yulong's DAH1 which cost 3x than this DAC, althought the DAH1 is better but the ZERO's cost/performance ratio is certainly better smile.gif Anyway, guys here got Yulong DAH1, iBasso and Musiland MD10, perhaps we should do a real head-to-head review soon tongue.gif
