Chua, thanks! Yes, the Neutrik RCA socket at farnell is really cheap at RM6.50 each. I wonder what's available at Octave so I don't have to wait for shipping. I was told they moved to a bungalow house near Amcorp Mall, is that correct?

GL, yes, I agree Silver would place a bit more emphasis on treble. I prefer to have something more neutral like copper. The Neotech cable looks good actually! Take Five Audio also have Cardas Female RCA connectors for CAN$10.95 per pair. Vampire Cryo treated RCA is CAN$16.95. Quite a bit more than Neutrik but I wonder if it's worth it since gonna DIY once and then use for years... Or maybe can check if can bulk from Audio-GD if they're cheaper?

Abel, how does it sound now after burn in? I'm actually arranging to buy the IeGO cable coz they're Cryo treated and have very good review comparable with US$300 cable. But I still need 1 cable for my conditioner... unless I change my wall plate to US-type also...

Hi RAV4,

Octave have Switchcraft RCA which is very good for CD, AMP or DAC, if is not misstaken is RM35 - RM40 per pic, Is you looking for better one you ask the Boss (Mr.Yap) to order the ETI RCA for you the RCA cause RM180 per pair.
Switchcraft RCA is much Natural & warm.
ETI RCA is more to Clearn, Dynamic, and fast signal pass to.

It is depend what is lack out from your system, that is nothing is better and better, event you can use back your original RCA and change the signal cable to sliver or pure copper cable. that will give you alot improvement already.

Thanks

Which Switchcraft RCA model are u refering to? Seems abit too overprice ... with than kind of money, can try the revolutionary Eichmann Bullet Plugs, i think Octave does carry these too, last time they quote me RM32 each ... after some extensive review by user around the globe, they really do HEAR some improvement over conventional rca plug ...

Eddy, if possible please do try this, worth a gamble! biggrin.gif

HI GodLuvSxS,

Echimen is ETI, i think you mention the one cost RM32 is switchcraft RCA (octave only have one Model) and normally we call Short head.
No more try cause i have been tried too many, i got furutech, WBT, AudioNote, Cardas, switchcraft & ETI. smile.gif

For me i still prefer Point to Point, no RCA socket no RCA plug is the best. tongue.gif

Hi Chua,

Friend dun put me on top of the “GOD Table” I am not an expert or Master in TDA5141, I Just like the character of BlackGate Cap & TDA1541.

From my experience those transparency & soundstage is given by the pure silver cable, but would you feel that after installed the sliver cable you can hear a lot of ssss from female vocal.

FYI, the Sliver cable need 500 hours for run in, then only it will get more neutral.

If you want to try copper I have some 0.26mm/0.1mm Oyaide 4N pure copper, I believe the one that you bought from octave is 0.3mm sliver cable.

Dun depend on the outlook to judge the thing whether good or not, you must try it and feel it. Hehe..

ermm i audit chua DAC is really give alot different the silver wire i wanna go octave to get some for my CDP.

hi eddy now black gate really out of stock due stop production ..... i not yet try on BG due costly i just use Elna Silmic or Silmic II
now i also plan to change opamp for my CDP dunno which one to use wana try for AD8066
*
Dun wasting time to try other OPAMP ask Chua to get the OPA Sun from Audio_gd and change the OPA powering caps to blackgate. It will give you a big impression on that.

Blackgate are expensive but the improvement is unbelievable.

ok thanks eddy but i cant use OPA sun due the original opamp is surface mount type and is located bottom of the PCB board.

Able to take photo of your CDP? i would like to see how they solder the OPA on your CDP.

We are talking about ZERO and the costs performance ratio it can provide. We are happy about it and it is not our interests to show other unit more superior.

Friend, nothing is the best, and if i not misstaken you was planing to change your DAC before.
Just wan to share with you that in the market still have a lot low price DAC and sounded very good DAC.
Normally how we improve our DAC is listen to other DAC then inprove from your DAC.


If you think that is the best then that is the best loh..........

Woh... the chip is solder under the borad... that will be abit hard cause need to take out the chip and drill 8 hole on the board and solder the cable on top of it....

i need to have a look on the board then only know whether can put in the OP-AMP or not.

Thanks for the prompt reply. How does the Zero compared to the rest of them?

I am not sure cause i have no change to try on teh ZERO DAC, but i believe the ZERO DAC still can improve a lot by changing the some of the caps.

one thing i dun like about the ZERO DAC is because of the ZERO DAC it using a single unit OPA output. If it can make it 2 OPA output that is much better. This is all my opinion.

Hi RAV4

Yes, Old Klang road (Sri sentosa) smile.gif 0.1 is not suitable to internal wiring, but if you want to try the different betwwen the 0.1 & 0.3 i have some used one.
i dun know how much cost for it, free to charge lah.. cause the thing not cost a lot and i guess 10cm is more then enought for you.

Oh, I'm not scared of the soldering. That's a simple enuf job. But to try and listen, then remove n resolder to compare .1 and .3 is quite cumbersome so having 2 units is useful for comparison. I believe that's also why Chua bought 2? ;-)


Added on September 30, 2008, 11:17 pmEddy, you mentioned about Black Gate caps so I did a search and found that they're indeed very costly and also scarce. Some are like Euro 10 each! So where do you get your stock from? Actually just curious but I think modding BG for Zero is rather extreme? Might end up to cost as much as the unit itself...
*
All my stock is from Japan, but now i can't get any more from japan already. I think you still can get from other place like
http://www.acoustic-dimension.com/blackgate/bgmain.htm

Yeah, Blackgate is very expensive compare other caps, but if you have listened Blackgate i am sure you wouldn't want to take it out from your player or DAC. I would said you can't found that kind of clean tonality from other brand.

"Actually just curious but I think modding BG for Zero is rather extreme?"
It is depend on you, if you are looking better improvement on your DAC or player Blackgate is the better choice.

QUOTE(GodLuvSxS @ Sep 30 2008, 11:53 PM)
BG might be abit overkill for ZERO, best one would those Elna or Nichicon, quite bang for the bucks biggrin.gif If possible i think both the input and ouput rca female should be replace with better one, again garbage in garbage in, nice in nice out biggrin.gif
*
(this is my opinion) Elna, Nichicon, Muse, Oscon and some other NOS caps are good but it still can't give those kind of clean tonality.

That is another matter to connect the OPA. you need to find out the 8 pin connected to which resistors and Caps, then you connect the OPA extend cable to the resistor and caps.
Attached Image

+12v should be connected to one of the Elna caps and another 6 pin is connected toresistor another 1 is GND

Hi,

My advise better get a good soldering station & de-soldering gun, if not will easly spoil the PCB board.

If you affordable get Hackor Sucker (de-soldering tools) is around RM60, Waller soldering station RM240.

Yes, you did good choice. reading on Burson webpage If you palning to install the HDMA put in Elna/Blackgatge for the OPA powering caps that can kill up those current noise from the +12v.
