The Opamp wasn't backwards, but I'm certain it wasn't completely seated properly prior my readjustment. Is my best option to order a new opamp then?

Has anyone seen this? CD DAC Lampucera lampizator It looks really interesting.

Hiya Trans, if the op-amp is damaged, I would be tempted (highly!) to forget about it and go straight for an OPA Earth HDAM, it doesn't really get any better than that in there. Just order one from audio-gd and you'll have a cracking good DAC! I don't think you will find much argument about that anywhere in this thread.

By all means though, find another op-amp, the OPA627AU (they come soldered onto an adapter) or OPA627BP's on a Brown Dog adapter are regarded pretty much as tops in that position and they just plug straight in to the op-amp socket. There's loads of info in this thread about them. The OPA627's are single devices and you will need two of them to replace the dual 2604 that would have come with your DAC.
However, the Earth HDAM will take you right to the top. They are available from here: http://www.audio-gd.com/En%20audio-gd.htm or you can go straight to Kingwa and order from him, he's the big cheese there.

I was busy with the shigaclone cd player and then the usb to spdif converter.

I spend the sunday night trying to upsample, secret rabbit code, pphs.etc. until I gave up. Reason is I used the wrong USB/spdif converter. This converter results in 500ps jitter. omg.

http://www.ha-info.com/spdif102.htm

Now I am back with this potential USB/spdif converter hopefully soon from kingwa. the audiophile grade spdif with 20 ps jitter only.

Any more information about that kingwa spdif converter? Where to buy, what does it cost etc ...

Hi, just several words from my burn-in period with HDAMs.

My Earth has 60+ hours, Moon 50+ and Sun v2 only 6+

Today I found next good synergy candidate: Zero with Sun v2 in DAC > MAC AgQ IC > LD MKV > AKG K701

I didnt expect the AKG K701 to match with the Sun HDAM, but it is perfect. What impressed me most is the soundstage. I really start to love my AKG more and more. After several years with Senns (580 and 650) I really start to convert to AKG K701. With Earth and Sun v2 in Zero and LD MKV as HA, the AKG sounds so clean with impressive sounstage, dynamics and details never heard with any Sennheiser, very unexpected way from Senn-darkness. The Sun v2 with K701 is a great surprise for me

How would the headphone section of the zero compare with somthing like a Creek OBH-11. Thanks

for anyone looking to try some good resamplers for foobar.. check out SSRC
foobar2000用 SSRCプラグイン - ãŠãŸã¡ã‚ƒã‚“ã®MIDI/Audioソフト

or try SRC but I was having issues with it getting 192000 kHz using FLAC files

I am also curious about this..

 

[ccschua]

This will take time, it uses DSP for reprogramming. the difficulty is to achieve breakthrough in USB->spdif conversion. Current technology offers are quite limited.

 

[Deftoned]

I e-mailed them to ask at HA. But right after I did that I saw that the converter is now available through audiophilechina. 40$, about the same cost as a USB-TOSlink shipped separately. Is there any reason to prefer Coax over TOSlink?

Does this mean that it is better to go with optical? Thank you for sharing your findings.

Its been stated here that Zero owners prefer the sound of COAX to optical.

As a DAC alone is the upgrade version any better than the regular one? Sorry if this has been asked already.

 

[viscosity]

^^^ id say get the stock version and just get one of the hdams from audio-gd if your just using it as a DAC. simple opamp swap and you'll get some sweet sounds for minimal cash

Hi, everyone! I have just ordered an 'upgraded' Zero, my first amp. It's coming with a dual-OPA627 for the DAC, but I have no idea what opamps will drive the preamp/headphone section. Any ideas? The link is:

ZERO 24/192 DAC DA CONVERTOR, HEAD AMP(Upgrade Version) - eBay (item 110287182130 end time Nov-15-08 13:00:00 PST)

Also, I'm considering getting an HDAM as well, but can't seem to narrow it down based on research. If I were to choose one of either the Moon or the Earth, which should I order first and why? (I'll be using this with either a DT880 or HD600, or both.)
