digiZoid ZO2.3 Impression & Discussion Thread - Page 43

post #631 of 1009

Kenman, thank you for the answer; of course I have sent an e mail to Digizoid, but in the meanwhile I would see if here someone has found a solution.

 

I tried biamping (I also have a PA2V2) but I think that the SQ is much lower than the ZO2-HIGHGAIN solo. I have tried both mode: IPHONE/LOD/ZO2-LOWGAIN/MINIPLUG/PA2V2/HP and IPHONE/LOD/PA2V2/MINIPLUG/ZO2-HIGHGAIN/HP.

and it's also too bulky

Hmm...all this talk of low volume is starting to worry me because I have all of my music files adjusted to a loudness of ~80db using mp3gain. I'm planning to use it with fairly sensitive/low impedance IEM's so hopefully this is all going to balance out nicely.

PierPaolo: Not sure if it will be worth it to you, but I had the same issue and Digizoid offered to adjust the gain for me. I decided not to bother since I loved how my IEMs sounded with it, and I've since found that my Beyerdynamic DT1350s also work great with it. I prefer to use the LOD, like you, but if you adjust things properly using the headphone out and the high gain setting on the ZO is a perfectly viable option...that's how most people use it anyway, from what I understand.

They BA based? If so, I'd hit up digiZoid with the sensitvity and ask if you can send in your ZO2 and get it tweaked to pair better. I've noticed some hiss or static like noise with no music playing when I pair the ZO2 with BA-based IEMs. Otherwise, IEM's are not an issue. In fact, I loved the combination of my ZO2 with the NuForce NE-700X's a lot, and never noticed any hiss at all.

I haven't received the ZO2 yet. I currently have 4 IEM's, but I think I will be using the ES5 most often. They have an impedance of 20ohm and sensitivity of 120db SPL/mW. So far, I'm not experiencing any hiss with any of my stuff so I'll keep my fingers crossed.

If it hasn't shipped, ask them to tune it down for you, it will save you some time. I've talked with digiZoid and they've remarked that the tweaks performed will have relatively little to no effect on it's abilities to perform it's job as it would without the tweak, just better with BA based IEM's than it's non-tweaked bretheren

@Zeitfleisst:  I've got a set of es5s that I've used with the zo2, and the impedance isn't really a problem.  There's some minor hiss that's present during silent passages, but once music's playing its nonexistent.  Can you share your impressions of the zo2 with your es5s when you get it?  To me, the zo2 makes the es5's sound feel fuller, thicker, and even more musical, with the loss of some transparency, micro details, and slight roll off at the top.  It's great, but I have to be in the mood for it.

Be curious to read what you hear. etysmile.gif

Ah I see. As long as the hiss is not a major problem, then it's good. I'll let you and everybody know how I like the zo2 with the ES5 for sure. I think I'll love it since I'm somewhat of a basshead bigsmile_face.gif

I saw someone post that the Fiio L3 cable does not work with the ZO2, and I just tried it and I think he might have been right. I'm getting no sound at all from my ipod using the L3 cable. I made sure that I was in low gain, and adjusted volume until it was purple and also even made sure I got the input and output right, but no sound. Does anyone know if an L9 cable will work?

 

***EDIT: Ah, never mind! I didn't get the plugs in deep enough, as I thought it was normal for it to stick out a little.

 

 

BUT there's another problem. The hiss is worse than I thought. It's pretty noticeable even at the lowest volume, and I've tried the headphone out as well giving the same results. Also, the sound is too loud even at the lowest volume in low gain. This is contrary to what someone has been saying above. I'm using the ES5.

Man, the hiss and the volume problem really sucks because I REALLY liked the sound coming out of the ZO2.3 even with the headphone out. frown.gif

 

Also, I almost blew my drivers out when I tried connecting to the Fiio E10. This thing is pretty dangerous...

That's really strange- I honestly get a little static in the background using my es5s + zo2.3 + iphone4, but nothing to complain of and I definitely can comfortably use the combo in low gain without it getting too loud until I click the volume bar a bit past mid-blue... I wish I had an answer to you as to why mine works and yours doesn't confused.gif.  Maybe ask Anaxilus- he's got a zo and es5s too.

Yeah, maybe we have different sensitivities to hiss, but it really does bother me. It's like a silent whisper going "pssssss....". And I know I listen at low volumes, but the lowest volume on the ZO2 was pretty loud when paired with the ipod classic, even for the average joe I'm sure. Also, when I slightly tap my ZO2 on a hard surface, the sound gets conducted through the wire to my ES5. Pretty strange. I've already sent a message to digizoid, and hopefully I can get an answer soon, otherwise I'll have to let it go and maybe wait for the next version.

First, make sure no wireless devices are near the ZO2. RF signals can mess with the amp and cause hiss. This could explain why others have not reported the same thing with the same setup. Also, the quality of your files may matter quite a lot.

If those things dont help, contact digizoid about getting it adjusted and let the bliss continue

I'm sure that it's not an interference problem as I've tried moving around the house and the hiss remains constant. Also, I've converted all of my files from FLAC->320kbps, so it's also not a file quality problem. The only thing I've done to them is use mp3gain to bring the volume down to 80db. And the sound being conducted through the wire as I've described above is just ridiculous. If I were to carry it around, I can imagine it would get annoying pretty quickly.
