1/4 jack is the problem, the biggest problem now is how i changed it?

Unfortunately, it isn't just a quick swap out of a switchcraft. You will need to desolder it carefully from the board, and replace it with the exact same type of input. Take it with you to the electronics store to be sure, most of those guys are pretty helpful (unless you go to Radio Shack, in which case don't listen to anything they say...).

it is probably just a simple 3 conductor TRS with a switching ground, but I haven't looked at it.
The good news is that the whole repair shouldn't cost more than about $3.50, assuming you have basic soldering tools.

I had a similar problem with my output jack. It actually had nothing to do with the solder connections. I would recommend trying some contact cleaner first before getting involved with swapping that thing. It has 8 tabs instead of pins and won't be much fun to replace. If it had a simple jack I would upgrade the thing but it's an annoying el cheapo.

I wasted about two hours thinking I screwed up my installation of a cheap attenuator because some oxidation on the jacks contacts were preventing right channel output. I even ordered the closest things I could find to replace the thing before I figured out the real problem. Luckily, they were only about $10 for 2 of them shipped.

The only problem im from Europe (Czech Republic), im thinking maybe LAWRENCE can send me a replacement part and i pay to him by paypal or something, ill try to send him a email.

Do you think i can find something similar online somewhere?

This is the part I ordered. PC mount 1/4" jack Stereo 9 pin Fender amp 88-99 H507-A - eBay (item 180373875682 end time Nov-23-09 02:31:53 PST) It was not easy to find a replacement for the stock jack. I never did put one in though, as the contact cleaner took care of the problem. Try some of this stuff if you can first.
deoxit, great deals on Electronics, Musical Instruments on eBay!

i did some opamp rolling. i had started with LT1364 (dac) - LT1469 (amp), but the sound was bright and the treble was too harsh for me. after some combos, i settled on LT1469 - LT1361. it just sounded more balanced and the imaging was better.

this unit is a great place for audiophiles to start

Hi,

I stopped using my Zero( on year or so old) for several months, and wanted to try it again with a Hiface 192kHz USB to SPDIF converter (excellent value for money by the way)

Very nasty result : 16/44.1 works perfectly, but anything above fails (enormous distorsion) : 24/96 or 24/192 namely.

The same occurs if the digital message goes first through my Tact 2150, redirected to the Zero through the amp digital out...

Using my CI Audio VDA2 and a Trends PA10 headphone amp in place of the Zero with the same connections works perfectly well at all frequencies.

Any idea to solve this issue ???

 

[oatmeal769]

By 'up-converting' the native stream outside the DAC, I think you are probably changing the code - i.e. the DAC can't read it. Solution would be not to use the adapter.

 

[sadhill]

In fact I am NOT upconverting the stream : I was speaking of reading 24/96kHz or 24/192 kHz FLACs unmodified...

 

[oatmeal769]

Hmmm... That's just weird. You'd think that if it was some kind of 'conversion' issue, it wouldn't do 16/44 either. I'm out of ideas.

 

[sadhill]

As the same setup works with the CIAudio DAC (at least for 24/96, as it is not capable of 24/192), I would rather fear a hardware issue with the Zero...

I did try something else : send some 16/44.1 in the Tact RCS Preamp and output it upsampled 24/192 (the default output for the RCS) to the Zero: doesn't work either.

 

[Kitarist]

So guys is it still worth it?

 

[Mangemongen]

I'm looking for a USB/DAC/Amp that can play 24/96. This isn't the one?

Edit: Without a loss of quality, considering I have access to all my favorite songs in 24/96 lossless vinyl rips. Almost.
