Review: ZERO 24 BIT/192KHz DAC/Headphone Amp/Pre-Amp

I got mine from Lawrence since he will upgrade your opams.

Anyways that is pretty quick and good job on the repair. What phones are you using right now and what music are you listening to right now. I want hear your description to see if they sound similar to what I am hearing.

I assume you were asking me -- using my HD600s almost exclusively these days (except when I need closed phones). I'm not great at these descriptions of what I hear, but I'd say it just sounds more - lively. More dynamic. There's more punch to the lows, more conrol in the mids and hi's - seems like the slight sibilance I was getting in vocals is gone, too. I don't use the amp very much at all (go to my LD MKIII) so I can't speak to that yet, but as a DAC the Sun is easily better than the OPA627.

Thought I should add that when I told Kingwa I was able to fix it, he said that was great news, apologized for the poor quality of the leads, and offered a discount on future purchases. Very nice gesture, I thought. Greeeaatt.... just what I need, an excuse to buy more stuff!

Ha! Well I did it. Honestly the hardest part was stripping that dang tiny little wire. I practiced about 25 times on ll different wires and STILL snipped the end the first time! The thing is super thin and TOUGH - much tougher than other cables I tried.

Anyway, worked out in the end - Sun is in there and working, sound fantastic - just what I was missing (I think so far... time for burn-in!). Attaching to the unit itself was MUCH easier than attaching to the adapter (or plug or whatever). Oh I did this with no helping hand tool, just APs advice for taping.

Thanks to everyone for the input and advice. Soldering is ridiculously easy and much less expensive than I thought. Oh and no pictures because A - I'm NOT taking this thing out anytime soon, and B - I don't feel like being scrutinized today!

Ok, I have taken some time to listen to both the OPA-SUN and OPA-EARTH and here are my early impressions. Notice that all impression were done with HD580's and neither the Sun nor the Earth were properly burned in.

The Earth has a slightly more bright presentation with a lager soundstage. In fact the soundstage is so spacious on the earth you sometimes second guess the fact that you are actually listening to headphones and not speakers. I have also noticed the earth's sound is slightly more textured.

The Sun is a slightly more dark intament presentation. The soundstage is still really good but is not as wide. The bottom end on the Sun is slighly more pronounced which can be desired on certain music.

Overall I have decided that I enjoy the Earth better then the Sun in the DAC section of my Zero. Although the Sun does have some pretty cool green lights.

Oh yea I also installed the units using cardboard very similar to what AudioPhewl did one page back.

kejar31: That's interesting - I put the Sun in first and will have to have a go with the Earth soon. I agree about the bottom end with the Sun - the very low notes have a lot of power, whereas the midbass I feel is slightly less than it was with opamps.

It IS kinda fun... and I'm most definitely a geek

It's kind of empowering to know how many more things I can fix - and how EASY it is! Like in a twisted kinda way I don't have to be quite so gentle with things anymore. Or I should say, I no longer have to worry about my meat hands (which aren't capable of being gentle).

I too am with SUN and EARTH today. I have the new SUN sat in one ZERO and my previous burnt in HDAM (AKA EARTH) sat in another DAC. After listening to some ORB, AMY WINEHOUSE and BAHAUS I can't say that there is an awful lot between them at this point. I'll have to burn in the SUN unit for longer of course, but at this point I have to give the nod to HDAM-EARTH.

Keep it greasy, so ...

You know, although I haven't tried my Earth and probably won't for a while, when I first read the descriptions I thought I'd like the Earth more - sounded like it may be more neutral, and perhaps have more detail.

Then I read that most were going with the Earth first and a few early but glowing reviews of the Sun - so I figured I break the mold and go Sun first. I likey so far!

I'm been looking at using an acrylic cover on another project. An acrylic cover for the ZERO may work. Maybe even an entirely acrylic case

Good job kejar31....these things are difficult to describe and have it mean anything. You managed to give it real meaning...thanks

Peete.

You know I noticed something else when using the SUN. When using it in line out mode to my speaker rig for burn-in, I noticed I was still getting a small amount of the signal leaking into my headphones. I'm wondering if others have noticed as well? It does not happen with the Earth.

Most likely the gain difference between the two modules. My best guess so far since my modules haven't arrived yet.....
