Now if we could find one like that only socketed!

Well, I think I don't have enough hours on the AD797s yet. I'm going to swap back this evening and run 'em for a couple of days.

I just noticed I have some 744's and a 746. I don't have a Zero but I will have to try the 746 in the P2. It will give me any idea of the sound.

Happy New Year Ya'll.

My first post here from Canada =)

Just picked up the Zero from Lawrence. And is dead after several critical listening/comparison against with my Northstar M192 DAC and YBA Audio Refinement Alpha CDP. But at least it did a very good comparison with my Northstar, which is one of the best DAC out there (especially in reproducing lifelike instrutment music - violin sounds like violin...etc). i give it 80% sound to the Northstar and closer to 90% with the YBA. Is certain a killing upgrade for any mid priced player, in my case - Sony DVP3000 and Sony DVP7700.

Anyway, I used it as dac + preamp to drive my tube power amps for several times, and music suddenly it become silent slowly. (anyone know what is dieing?)

Meanwhile sending off to local tech, would like to also upgrades the opamp you guys been talking about. My taste would be realistic music reproduction. I can give up bass or absolute quiet noisefloor. Burrbrown has been described with a wall between the ears and music. So should i look at AD? as my beloved Northstars is using AD opamps. It sounded best anything i heard with BurrBrown except BB has more killing dynamics and speed over the Northstar, but Northstar still sounded more real.

Thanks in advance for any input... i really liked the Zero DAC, espcially Lawrence gave me a hint that after upgrade, it might sound even better than my class a Northstar DAC... which i wanted to find out

P.S absolutely stunning photos Jamato (san?)

Let me get this straight: How are you connecting what to where?
I believe that you connect your PC to the Zero with Optical and then connect the Coax to either TV or Xbox?
That can not work, as the Zero only has two Inputs but not a digital Output.

Or have I missed something here?

Digital Coaxle in > PC (my PC has both optical AND coaxle)
Digital Optical in > TV

No outs. You are correct.

Good news guys. The problem with the xbox was just a setting I needed to change in the dashboard. So as I suspected the delay issue was with the TV, not the zero. I can live with it, cause I mainly wanted to use the zero with my xbox and PC. Odd, I guess the optical section of the TV didnt get much thought.

 

[Henmyr]

Would this Zero be an upgrade in any way over modded Xfi + Headfive for MS2i/DT880/DT990?

I've read that AD8397 is a good opamp for alessandro headphones, so I might want to test that one. Which op-amp would pair best with it, and would it be best to have it in the dac or in the amp?

Yeah same here

...all there is since the 27th

Ordered an OPA627 module for the DAC and a pair of DY2000 (metal) for the Amp. Hopefully it will make the angels sing through my AKG's

JonM, Thats great! A side thought. If your TV is newer, some manufacturers have updates you can download and push to the TV. Could yours be one of them? Later..

Easy to listen to, easy to pick out every last detail and ever so natural. There was an ethereal quality to the sound that only ever heard on high quality loudspeaker based systems. It's hard to put what this op amp does into words but listening to the sound with it on board is as close to headphone heaven. Very analytical. So I've determined that LT1057 (DAC) + LT1361 (amp) will be my first upgrade attempt. If I feel completely satisfied I might just stop there.

Ow Beans!

Both of you guys will probably get a knock at the door before you have any real status! This is usually what happens here too.

 

[Penchum]

Well, Zero #2 is about 40 hours into burn-in, and already it is sounding better. I'm sticking to the default Opamps until I have 100hrs on it. Hopefully, my LT1364's will arrive before then. My original hope was to put AD797s on adapter in the DAC and LT1364s in the headphone amp. This still may work out. Gotta order another replacement knob!! This guitar amp one is driving me nuts!!

 

[smirnoff04]

Woot. The Zero arrived today. I can't wait to get this thing home. I'll try and post my early impressions of it, though I don't know how valuable they'd be since I've got so little to compare to.

Hey, thats great! I imagine (based on your handle) you might break out some drinkin stuff to have a good first listening session?

Let us know how it goes!!
