I think the cap bypass + franken is good to do. it will add more ommp to the output power/
*
actually those are not call bypass is call decoupling

Ceramic capacitors, which are often used for decoupling have the property that for higher capacitance, the ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) is also higher. To provide adequate decoupling for both low and high frequency components, a high value capacitor (with high ESL) is used to take care of the low frequency components for which the higher ESL is insignificant. Another lower capacitance capacitor is connected in parallel to take care of the high frequency componets for which a lower Xc is acceptable, but a low ESL is required.

Two capacitors of equal value in parallel, will, in general, have lower ESR and ESL values thatn a single capacitor with twice the capacitance as each of the lower value capacitors.

Yeah, the green sausages are connected in parallel so bypass is more a coin word but it's technically wrong.

Abel, so what you're saying is "decoupling" is an easier way to upgrade but it's still best to replace the cap?
*
if can replace cap and decouple with green sausage will reduce the noise ... if to big can buy lower volatage

Cant wait to get there LOL looking forward to see the real potential of DAC100, with chua's scary blue snake powercord, that would be fantastic! It's currently "forced" to pair with my Aego 2, which I believe it's limiting it's potential ...  tongue.gif

Zero new user report in!
I just get a zero with op627 get from jaben bundle package.
Damn impress for it performance!
May I know does op627 is single or pair in the so called zero+?
does the earth,moon & sun hdams is playing different role with the op627?
I'm using esw9 with my laptop, with this powerful dac n the laptop output,does it still need amp to drive it?
sorry,still very new in audiophile so the questions might a bit stupid.;p
*
i can say OPA sun out perform than opa627
opa627 is single channel that y it need 2 opa627.
OPA-SUN is call discrete opamp and OPA627 is IC opamp


Added on December 21, 2008, 1:26 amermm Audio-GD soon coming out DAC + Headphone amp come something like ZERO with Coax , optical and USB thats very good news
found the design not bad dunno wut the price range

for DAC i prefer those old school one like using TDA1541A DAC 16bit non-oversampling

bcoz i found alot of 24bit up-sampling DAC sound bright n thin 20bit not bad also like those BB PCM1702

I may start low first ... nearfield listening setup biggrin.gif Looking for something like those RM800ish speaker (Wharfedale Diamond, AE Neo, PSB B1 etc) + T-Amp(bang for the buck, details yet decent enough power for nearfield or small room enviroment), may spent more on IC and Speaker cable, targetting D102 MKIII and Royal Jade (got some lubang from my China friend brows.gif), musical is essential cos next level upgrade would be Audio-GD's higher end DAC which quite certain to be highly transparent + very little musically, thus VDH may accompany me till the end biggrin.gif
*
heheh VDH alot of fake one just beware .... if can try to find mordaunt short carnival 2 like my one sound are better than Whafedale .... easy to push 90db sensitivity

Still not yet join the CD63 gang, but looking forward to sell my DAC100. I think it's time upgrade to bookshelf setup, Aego 2 seriously lack the depth and musical of bookshelf setup, thus gotta sell my DAC100 to fund my bookshelf project. RM600 shipped brows.gif Interested? Seriously it's a step higher than stock ZERO + EARTH discrete opamp, as Abel and Chua mentioned, it's comes with very low distortion, very detailed yet it's clean and smooth, somemore it's quite sensitive to power cord too, we changed 2 power cords in the process, I can easily tells the difference between them, I'm a power cord believer now!!!
Van Tan Hoh is really good, natural, without any emphasis on any frequencies, no wonder it's selling like a piece of hot cakes for decades!

CD63 is quite good, almost perfect to me but IMHO with better soundstage, details and tigher bass, it's full marks! Something in between DAC100's transparency and CD63's musicality would be the best and most balanced!
*
but i can say stock CD63 the bass are very loose and no energy just emphasize more to midrange to high but not low ... smile.gif
that y need to upgrade the opamp and clock system ... if u want more tight bass than must go to put in some pintu-hitam (blackgate) hehehe

wut i found

DAC-100 (with OPA-Earth) = the sound are smooth , low distortion compare to Zero (with earth also) one words more refine but i prefer DAC-100 with OPA-SUN

but overall i still prefer my CD63 heheheh tongue.gif

CHUA, Franken Zero as in your unit with the Buffer Stage mod still lost out to DAC100? Hmmmm......

OK, what was the transport used for the Zero? CD63 or DVD player or Laptop via digital converter?

STEVE, thanks for your advice! I could have ended up with an Aego if you didn't tell me to stick with separates. Now I have to think of what amp to get.

ABEL, wah.... strong selling on CD63... 1 Penang fella just sold a KI at rm400.

THANKS for your feedback GUYS! Very informative! But a bit more headache for me...

i think is not KI just CD63 MkII if KI worth RM1k
