I usually have the zune @ lvl 18 volume with Zo2 @ 15 and control via zune.  I was testing it out for users who will be using their Line Out connection who have no choice but max volume from their source. =)  I'm using it with my headphones and it's loud for that.  I can only imagine for IEM users x_X;

Yea looks like ZO's already getting a bit too powerful for some IEMs, hence the growing need of a high/low gain switch. At this point I'm just glad I'm not an IEM guy so don't have to worry about hissing and too high volumes. The headphone I currently use is rated 64 ohms so should be fine.

The minor hiss issue is something that everyone should be willing to tolerate for a $100 amp.

 

The LOD volume scaling issue, not so much. The whole purpose of including a volume attenuator on the unit was so people could run the ZO2 through a LOD.

 

In the next batch, Digizoid should scale the volume back a bit since it seems that people with headphones and IEMs universally find it set too high (of course IEM users are suffering more).  It might lead to a slight delay at the factory, but it shouldn't be that hard to revise.

 

My 2cents.

I don't think price is even an issue. We shouldn't have to tolerate a hiss at all. I think it was a problem that flew under the radar regardless of the price point and should be fixed. 

 

Heck, they even advertised:

 

"Smooth, noiseless transisition into standby (bypass) mode New"

 

but now I think they changed it on their site to say:

 

 

"Faded transisition into standby (bypass) mode New"

 

So idk. It is a little disappointed I waited so long for a product that isn't perfect. Say what you want, but having to deal with hiss after shelling out $100 and waiting several months for an updated product is slightly disappointing.

Agreed, the most important thing would be to get the volume levels appropriate for LOD use at this point. A gain switch is something that would require a bit bigger change in the layout and would be best to wait for future versions (ZO3) but if this volume control is tweakable then I'd say go for it for the next ZO2 batches even if it might delay production slightly.

I would even be happy with mod instructions (do at your own risk, warranty void, etc) if it turns out that I can't use this with my IEMs.  I'm moving away from full sized cans so good IEM performance and volume control is essential.

I think what's frustrating is that Digizoid had built up such a solid fan base that all of us would have been willing to wait another month or two without too many people grumbling. Instead, even with the delay, the product they released feels rushed and incomplete.

post #84 of 1126

Seems so. They must know about the hiss, otherwise they wouldn't have changed the advertising on their site. I wonder what they have to say about that.

Damn. Not happy to read that. The hiss of the ZO1 was its worst flaw IMO, next to the loud on/off click.

Guys you're jumping the gun. The hissing problem you're all complaining about is annoying but it's quite an easy fix and it's not even overly expensive to fix. All you need is an impedance adapter you can find them for cheap in plug form HERE on eBay. You can even get one in cord form if you so choose. Yes it sucks in that it's one more thing you have to remember to take with you but it fixes the problem.

You cannot use impedance adapters with multi-armature IEMs with crossovers, it changes the sound very audibly to the worse. And those are the phones that are most hiss-prone, usually. Not to mention one really shouldn't have to add another cumbersome piece to a portable setup as a hackish fix for a flaw like that.

Have you tried it? I've run across enough people on here who have and they seem happy enough. If it's a no go for you and the hiss is intolerable maybe it's time to think about returning the ZO for a refund.

Yes, I have tried it with dozens of armature IEMs and various impedance adapters. You can check my signature for my reviews - I always mention when things don't work well together, regarding impedance matching issues, hiss, etc. I also gave the ZO1 a glowing review despite its flaws, since I was looking forward to the ZO2 fixing at least the most serious issues.

Crap sorry to hear it there's got to be some way of getting rid of that hiss? Oh by the way I've read some of your reviews and it's nice to finally meet you. Love the site don't change a thing.
