Yes there is budget way and expensive way of doing things. I like the way zero dac is being implemented, the choice to opamp rolling. it is very fun rolling those opamp, if u have the time, try the LT 1057, LM 4562.

Lawrence says LM 4562 is suppose to challenge the OPA 627.

I notice AD are seldom used. if u look at AD 797, it was once so popular, that those marantz player sure have it.

so good to know the soundstage get upgraded.

Wow the mod that I have been waiting for. Please see for yourself how highly rank is ZERO DAC and the great potential in the Lampization mod.

please take a look at this.

http://www.lampizator.eu/LAMPIZATOR/REFERE...AC/ZERODAC.html

I hope someone can do this for me, our homebound Empire23.

If Empire23 willing to do it, I would start sourcing for components too biggrin.gif
ccschua
Yeah and I think the costs is not high. The improvement is basically coming from the removal of opamp, instead uses tube buffer, which is more desirable. It looks to me not somany component is involved, so it would be kind of easy.

so can call Zero tube.

Not easy to hide as the heat built-up if put the tube inside the housing smile.gif

I doubt it will be hot inside, since the tube is meant for buffer, the current out will probably in the mA range. some of the CDP and DAC also have the tube reside inside the casing, but with proper ventilation.

The tube being install outside helps in the rolling and changing of tube, and also to know if its working.
empire23
^ problem is never really with the tube most of the time. It's getting someone to cut a hole through that steel, deburr the edges and attaching the necessary mounting hardware tongue.gif. I used to be able to do casework, but when i moved house, my BD RTX-1 was lost, probably stolen by the movers, so case work would be shiate hard.

Over here i just swipe my card to enter the mech lab laugh.gif. Going to build mah biggest amp yet. Hopefully my folks will find the time to send over my soldering iron. I'm planning to get a DAC to play with as a sideline.

wow now Zero getting hotter here tongue.gif

I dont remember liao who is Uncle Liew.
I went there once for installing HU and 2nd time for wiring the amp.
I quit 6months later after the blardy immo salesman show me how to steal my wira (with anti theft mod) in less than a minute and also started the car. I was stun beyond belief.

46381 a bit hard to find liao. Lastime I forgot who I bought it from in the famous ICE forum. Now Im using 5100UP which is a bit cheaper. 14AWG copper wire cost around RM8/m from Jalan Pasar. Also bought Belden 8760 for RCA cable. I think 8760 is slightly better than Canare L4E6S. Canare cable make my speaker sound bright.

yeah i got few Canare rca cable sound bright also now i trying their new cable call GS-6

chua, i like zero dac with tube/buffer there.when we will start and i'm willing to give my dac for that experiment drool.gif

i'm going to amcorp mall to day to find new interconnect.will bring transparent 100 link as well and test them before i get the new one.
i guess i think a good interconnect cable for my after raya speaker.... .(epos 12.2). thumbup.gif

@GATEVALUE,

Do you get the diff if you use the switch at the bottom of Soundstage, forward or backward is better ?

Mind to share , 10Q.

wut i listen marantz CD-63 KI sound better than go thru Zero i plan to go for NOS DAC

Maybe add a switch to it, so can select , like the op amps .

Better can be used as line in [analogue ] to get buffer , warm tube sound before output {if there is a switch/choice}

Sometimes, too hot to change the tube.

I also wish to try AD797 too, it's mentioned to be quite natural and warm compare to the AD house sound, but too bad it's not stable in the DAC section sad.gif

If your computer got either SPDIF out or coaxial out, then you could connect the DAC through one of these connection.

NOTE: Red circled is Coaxial, Yellow circled is SPDIF


If your computer dont have these interface, then you could get a USB to SPDIF converter. Plug the USB cable from your com to this device then link the spdif cable with this device and DAC. Then it sings biggrin.gif

Hi,

How much a coaxial cable costs ? A value for money one. Where to buy ?

I saw someone trying to sell a used one for more than RM 600, costs more than zero dac.

Yes, this thread is very poisonous, You need to have the will power to overcome.

Zero Dac is just the beginning of the journey [ searching for a better sound ] , and not the end yet.

Later, the power cords, tubes, interconnects, speaker wires , tube amps, cdp, speakers, moldings. It goes round and round.

It is going to burn a big hole in your pocket, be ready for it.

I think CMY was selling the cheapest QED coax around 200+ at the AV show. Maybe you should go to Sungei Wang to check out the few audio stores there on what's available. Stay away from Monster tho. Most have shared that their product in general colours the sound.

my system falls into low to mid section

the weakest point is the cdp, so thinking of adding a nice dac to it, thts the 1st baby step i guess tongue.gif

others i dont dare to seelor...if really wana upgrade, each item will be few k... sweat.gif

RM600 for coaxial cable is kinda overkill to me. Last time I seen some seasoned audiophile recommend only to spend 10 - 15% max of your total budget on cables. Let say u wanna spent RM4000 on setup, so speaker cable + interconnect budget should be around RM400 - RM600 tops biggrin.gif

My interconnect and speaker cables combined , are exceeding the 10% limit.

Maybe I should get a Jalan Pasar one this time.


Anyway, thank you for your reply.

P/S : Why don't you sell multi products like Tong Lee or CMY, instead of zero dac standalone.

We really miss your unit. All we try was a new unit, which is my unit. The new unit sound a bit harsh, need burn in. Now my unit end up with SKY 1809. Hope all owner report in and madmen can update the owner list.

I have been talking to the designer of HDAM, and he is very helpful..

This is the final part of mystery (I dunno how to upload all picture)

bo ccschua, i dont ahave coaxial cable (just realize).
can please recommend me a coaxial? cheapo one affect the SQ?
Thanks.

p/s": nice to meet you all.

On the coaxial, they are some poisons. Some say the expensive can give u the warmth or the neutral type, price up to RM few hundred.

But if u want starters, can talk to Abel. He can make some good coaxials or even pcworks I think. have u tried the optical or not.

Quite busy with some paperworks tonight.

I intend to pair with my 2 very old cdps ( more than 10 years cost 1k n 3k ), I hope to add value to these cdps.

Do you use the pre amp button ? Sorry no time to read the whole thread. Still rushing the paperworks .

I like the volume control whereby the output could be controlled to cut down the brightness of sound. Signature does change from original cd player.

Still need time to run in. Seems to work well with silver interconnect.
ccschua
All I can after rolling the opamp, I still think the DY2000 gives the most forward vocal, and best of all, smooth. Hope to hear some DY2000 owners report.

Hi Chua,

Mind to share where to get the DY 2000, vocal is my liking.

Hope to get one before investing in good tubes .

So how does each of these differ? What type of sound signature would it provide?

Zero dac hmm smile.gif
I am interested in getting 1 but i wonder can it drive high impedance cans like dt 880 600ohm and sen 650?
Anyone try zero with these cans?
Mind giving some review how do they sound when pair with it?
Thanks

I own a pair of darth beyers (modified beyer 770s) and find that they are sufficient in driving the headphones.. you can also ask madman as he owns beyer DT990 250 ohms...

tried with Senn HD650 (300ohm) n yes can push no problem... my DT990 is 250ohm so no problem. 600ohm dunno.

synergy is ok with my DT990. but i listen to metal, so the stock headamp is a lil too laid back for me. i ended up using my battery cute ii amp connected to the zero.

and the zero does NOT come with RCA cables.
