Review: ZERO 24 BIT/192KHz DAC/Headphone Amp/Pre-Amp - Page 625

post #9361 of 9370

ZERO 24 /192 DAC is better than Asus STX?

ZERO 24 /192 DAC is better than Yulong U100?

This is probably a bit of a noob question, but here goes.  I have the Zero hooked up to an Oppo BDP 103 and a Squeezebox Touch.  I can control the volume with the Touch remote, but not with the Oppo remote, which works fine when listening through my speakers.  Anyone know why the Oppo remote won't let me control the volume through the Zero?

Hi guys!

 

Does Zero accept 24 bits/192 khz via USB input?

My headphone amp has gone bad. Does anyone know where I can buy a replacement? I have to adjust how I insert the headphone jack and changing volumes creates loud-hiss.

My Zero DAC stopped working a while ago and now I'm looking to fix it. It is the non-USB version.

It just stopped working out of the blue. It powers on and the lights work, just no sound at all from either analog line out or headphone socket. I tried numerous combinations of optical, coaxial, RCAs, two different CD-players..

 

At first I thought that my crappy solder job had failed (I had two OPA627s on an adapter) but switching back to the stock opamp didn't do anything. How should I go about troubleshooting it?

 

Like I said, it just stopped working. One day it worked fine, the next day no sound. I didn't touch it in between.

Maybe some basic troubleshooting will help:

Hello!

My start setup was Yamaha CD-N500 as network receiver (gets flacs from NAS), Yamaha R-S700 as stereo receiver and Dali Lektor 2. I was really dissapointed sound after DAC in CD-N500 - pretty harsh, I could not  listen more the 10-15 minutes, so I bought small, not expensive but with good reviews dac SMSL 1955 (1st version with AD1955). After that  sound (instrumental, jazz, vocal, blues, some rock) became better. But I'm still looking for comfort, soft, velvet, enveloping sound.  Can Zero Dac help to find it or at least will be closer to it in comparing with SMSL?

I realize this thread is a bit old but just curious if anybody is still around. Worthwhile with HD600? I'm really not interested in totally modding it, maybe swapping opamps but not replacing the entire head amp. 

 

Alternatives would be Micca Origen/Schiit Stack/Aune X1S(way more expensive and less power).

My original Zero DAC headphone amp also just stopped working out of the clear blue recently.  Does anyone have a schematic for it?  I suspect it is the DAC board and not the power amp board because I can hear the hum from each channel through the headphones as I touch and probe the audio IC chip pins on the amp board. I can hear scratchy sound as I turn the volume knob so the amp portion is probably okay. It's the big main DAC board where the problem is.  I suspect it is most likely bad capacitors due to aging but have no idea which ones to start checking logically first.  A schematic diagram would really help. Anyone been down this path?

bad caps are easily spotted they will have leaks and or be swollen
