Review: ZERO 24 BIT/192KHz DAC/Headphone Amp/Pre-Amp - Page 601

Yes the Compass is a big upgrade over the Zero by a considerable margin.

Peete.

the voltmeter is, IMO, the best way to know if they are counterfeit
the 3 opamps in the Zero are DIP8 chips, they are designed to be easily switched

This is what mine came as. Sorry i don't have a better camera (recently broke, being repaired).

In very feint lettering it says:

BBOP A
627 AU
0003

Has anyone here tried the capacitor snipping suggestion? Is it safe to do and how much improvement do you actually hear?

I'm considering getting the moon for the DAC section but need more feedback about it first.

thanks

When trying to order opamp LT1469, there are a ton of them on the website with slightly different numbers and letter configurations. Which one is the correct one?

LT1469CN8

Peete.

@mplee79 and damsonlee:

So can I assume that you checked the OPA627 using a voltmeter? I am just being wary of all the fake OPA627 chips. :P

I personally haven't. I don't have a voltmeter. I'm worried that i received a fake one as well. If you scroll up, you'll see a pic of the 627. Bottom line though is if you are worried, order one as the base unit, and upgrade an opamp yourself. I'm switching out the 627 anyway so...

It all really comes down to the music...correct? So far i'm enjoying mine, so whether it is fake or not doesn't really matter.

Also, i don't have a base of comparison. You can get free samples from a couple places.

I personally only care about the longevity of the unit.

No, I didn't check it using a voltmeter. My ZERO had some very loud cracking noise when the preamp was turned on and it was found that the problem is from the OPA627.

I think so but I'm not 100% sure without getting a hold of 09 version for myself.

I have the PIO caps for a few kits but the rest of the parts you'll have to source on your own (for those that are interested).

Peete.

Mispost

i just wanted to know if you guys know the current seller of these zero dac's. I found some on ebay from an ebay store 'tam's audio'

ZERO (Tianyun) 24/192 DAC + Headphone Amp (OPA2604+USB) - eBay (item 350226989216 end time Aug-14-09 18:52:01 PDT)

this is the same thing right?

IE8?

Hello Guys,
i´ve got Sennheiser IE8 and Zero , do you think i can drive them through Zero´s phone out without any damage?I am worried because of their low impendance ...Does anyone use IE8 with Zero?
Thanks for answers.

You might want to pick up an impedance adapter. The Zero's headphone out is VERY powerful. Without one, once accidental turn on the knob, you'll be blowing both your ears and IE8s out.

Question... can I connect the Zero DAC-out to powered speakers similar to Compass in Super mode?

Does anyone do this? Does it hiss??
