[quote:089474a7dd="superwhite"]Hi WINDWSS,

Since so much problem to match with this n that, try to Mod the Power side first loh, more easy, no need to headache, that 1 wait until LAST to MOD loh, you still got so many thing to MOD, the biggest effect after MOD is POWER SUPPLY for the TUBE, especially the 100uF100V, 47uf 160V n the solen cap 1uf, i suggest GET THE BEST ONE, like AUDIONOTE, MUNDORF Silver/Gold, JENSEN Silver, REL-CAP or Cardas Cap for the 1uf value. the rest of the E-cap use the BG N series, will give you SURPRISE! :shock:  :shock:  :shock: (especially on SOUND n also PRICE)hehehe... :  :  : .[/quote]

I do a testing lastnight, change the elna silmic 100uF/50v to sparague 10uF/50v, so bass slightly soft&slow but detail improve, vocal more stand out and generally more musical... thus i guess if i change to BG N series 10uF or 22uF will have more improvement....

Hi viewer,

hehehe :  :  : , cheap specker, AE 109 floor standing.

Hi superwhite,

If changed to Jensen caps can help the bass.
what speaker are you used ???????????

Thanks.

Hi viewer,

Look like price not cheap, will compare whether change or MOD my existing speaker. can i change all the cross over cap to jensen copper oil, will this help? to improve the clarity n bass?

Hi Viewer,

Thanks, but i have try the sonus faber, floor standing, 2 way speaker, no bass n not up to my expectation, only good is name n expansive. PROAC n monitor audio not bad. will try out.

windwss,

ok la.......


thanks.

For solen PB-MKP-FC is it ok to be use in speaker cross-over since it is quite cheap.... since my AE use 3 cap -->5.5uF, 6.0uF & 8.8uF

maybe i just passby them with UCC SPP 0.1uF, shld be ok right?

windwss

solen scr +0.1wima black box is better.


thanks.

VIEWER,

u misunderstand i actulally asking which combination is better?
1) solen scr +0.1wima black box
2) solen scr +0.1 ucc spp

since both wima & ucc is sharp which 1 is best to match SCR?

Hi windwss,

Wima black box 0.1uf/400v costs HK$20 each.
I think wima box is not suitable with ucc spp cap, because ucc spp cap's sound is same as wima black box, if parallel with it the sound will very bright.
it better parallel with scr solen.

PB-MKP-FC  this is the old type of solen not good
The SCR is film & foil. normally the coloue of the side should be red in HK.
But also have black, gery coloue upon the dealer request. But the main body must be black colour, expect the high grade tin foil cap is white colour with black colour words for main body.

Thanks.

viewer,

by the way is teh PB-MKP-FC is sam as SCR? But i understand that the SCR should be film &foil right? what model of SCR i should buy for my opa coupling? i worry later my friend buy wrongly.... the new SCR should be whole black include the side is also black right?

VIEWER,

Forget to ask you how much in HK for the wima black box 0.1uF?

If do bypass/parellel, with SCR, wima black box or UCC SPP will give better effect?

superwhite,

so fast you change the panasonic cap. there is DNM interconnect for sale at 300 with bullet jack.

superwhite,

Thank you brother.....

after use the ZL on the power side, bass improve.... so quite satisfy at the moment...

for the tube i more frequent use eclipse pioneer, 2nd is tungsol, 3rd is WE since i seldom listen to pure vocal..... will return the we to u when collect the FC.....

Hi WINDWSS,

I have order Panasonic FC for 4700uf 25V 3pcs for you, will call you to collect when arrived. get your ZA series cap? Got any new progress? hope can hear any good news from you.

How about the tube testing, which 1 is your favourite? can state some or only one? :wink:

Thanks for sharing.

Hi viewer,

Just order the Panasonic FC cap, but only can get the 4700uf 16V, the 25V have to wait for 4days . but it o.k atleast got stock :wink: . plug only 2 cap at the power supply side, look like the bass is louder, i guest, have to run for few hour n see the changes. :wink:

Hi superwhite,
psnasonic FC e-cap is good for audio must better Robyon stardard style.
I think when you replace it, your cdp's sound will be muscial than now much.

I am wait for your modification.

Thanks.

Hi Abhader08,

True also bro, but i still have alot of thing to buy, like power cord, speaker cable, hope you can understand,  :  i know BG is the best, but my pocket not the best(eat also got problem) :  :  :

8000S is more than enough lah, only drive a chicken speaker. Thank you so much..... :

you want cambridge audio amp? are you sure?

hi superwhite,

r u sure u 12 try the panasonic fc e-cap, y don't u save that fund for a better cap, if the improvement is not much compare with the origanial cap then forget about it. if u 12 mod must go for the best cap.

Cambridge audio int amp for sale at only 590.00. what u think is that good value for money? how about naim 90.3 power amp for 1,500.00? audiolabs 8000P for 1,200.00? interested?

:  :  :  :  :  :  :

Hi viewer,

Thanks, your info help alot, we can't find nichicon muse n elna audio e-cap over here. the only i can find is panasonic FC. so no choice. :  :  Will try n see any different. :wink:

Hi superwhite,

Panasonic FC e-cap is quit good (musical) sound. which is for audio use.
other ELan for audio, Nichicon muse, EOR, Rifa is ok.
remark Rifa e-cap is high cost but lower than black gate e-cap.
Nichicon muse 90% same as Black gate stardard type.
Eor is very sweet and warm sound.
Rifa for high notes, very clear sound.
I also put psnasonic FC e-cap in my poocket headphone amp, it provide sweet and musial sound. it is 70% same to black gate. I think is situbale your cd 33. or Nichicon muse.
because you used M-cap it can make it soft.
black gate stardard e-cap provided powful than it.
black gate N type for outup.
Black gate FK and Stardard for power supply.
FK is high costs.
Just my view.

Thanks for sharing.

Hi viewer,

Thanks for super FAST response,

maybe will let it run another week to see any problem, if the problem getting worst, will exchange with new unit. :wink:

look like the BG price worst, until now cant change all to BG, any alternative? 4,700uF 16V  n 4,700uF 25V. Planning change to Panasonic FC, what do you think about the sound of Panasonic?

Thanks.

Hi superwhite,

I have try cdr in cd33, no problem.

but I suggect don't read cdr too much, because read cdr, the leaser light must be high, although the leaser head had auto detect. since then the leaser head's life will short.


Thank for sharing.

Hi viewer,

ask you some question, you have any problem on reading CDR? my one since o.k, but Abhader08 have problem on reading some CDR. is this bcoz of sony len problem? or the mechanism problem? pls help..... :cry:

Thanks.

Hi viewer,

Thanks for sharing, yes, over here have DAC, but not much choice, most of people here not knowing the DAC, so not so many shop import the DAC, but we have DAC Kit over here, but dont know the sound quallity :?

not going to try the DAC as no reference over here. will continue to MOD until sound suit my taste(cup of my tea).  :wink:

Hi superwhite,

My lite dac-ah was buy from 2nd hand market in HK at $480.00 only, brand new is HK$780.00  and mofidication cost used around HK$1,500.00.
althought cost is high, but its sound is better than some oversea dac price around $8,000.00 because i do have compare with my friends DAC.
They also buy it and do modifity.

It compare with MHZS CD33 after modified, the result is very very close
Is it can buy in your country ???????

Thanks for sharing.

Hi superwhite and windwss,

It is the original Lite DAC-AH reference photo (red pcb) for sharing:

Thanks.


Windwss,

spp cap is shap than scr solen. but scr solen is musical than it a little bit.

I use spp cap is base on TDA1543 is warm and slow sound, so i use it to let the sound clear.
If use in you CDP i think you can try spp cap will be make the sound clear.
up to your taste.

Thanks.

Hi superwhite,

I only like to coxial outup to DAC. because its sond become solid and 3D and
detail than optical output.

It is the fact of difference between coxial and optical outup.
You may try it. just fun.

I also changed the curists of opa from - input to + input, because china dac like to copy other DAC. so sometime has a problem. when correct that point, the sound is become real and 3D much than original. although the DAC is use Philip TDA 1543  eight pieces in parallel.

thanks.

Viewer,
your DAC很有型！If want me to mod like you i will 手软 :?
so i better just 乖乖do some mod on my cdp enough...
Since u had use UCC spp i would like your opinion.
Is ucc spp sound better than their tin foil cap? but the tin foil cap is more expensive oh!
compare UCC SPP to SCR fast cap(tin foil) any difference? i saw the price similar...


ahharder,
Don't scare buy superwhite... if u want the biedix 2C51 then much cheaper, the eclipse-pioneer (bendix old version) not bad, it is ~USD7only not include delivery cost yet... if u 12 try tell me lah... unless u like vocal very very much then keep WE396enough....

[quote:1b9fbc5b1a="WINDWSS"]viewer,

u now using CD33 with the lite DAC or using CD33 without using DAC?[/quote]

Hi WINDWSS,

Aiyoh....... ops:  ofcause if you use Standalone DAC you got to use the optical output lah(the digital signal before converted by DAC) ops:  ops:  ops:

[quote:e2254ebd96="Abhader08"]
Hi Superwhite,

How is my quotation?
Have you work out for me how much shouid i invest over all?
Where else you want to bring me for good Hifi shop?[/quote]

Hi Abhader08,

the quo with me pls come n collect, n the price :  :  :

As you know, over here how many shop we have, i think you have visit all the GOOD GOOD shop already, so...... :?  you still keep on asking? Go to HONG KONG hifi shop loh :shock:

you want Bendix? can, About USD160, are you o.k with this price?

Hi WINDWSS,

HAHAHA....... As i told you that DAC no doubt is good, but if you need BETTER sound you still need to MOD it, but i can assure that the MOD cost will cost you a BOOM also, you dont belive, ask viewer :wink:

both CDP DAC n standalone DAC have their own sound, so if you think that you want to use standalone DAC, choose the BEST one, if not you still need to MOD, if not buy the Standalone DAC, just MOD the CDP DAC loh, still the need to MOD what. if you need YOUR sound, right. you cant use 2 DAC at the same time.

Hi viewer,

Nice n Clean Job, well done, i assume the sound is sweet on your DAC?  :wink:

Thanks for sharing. enjoy the MOD process too.......

Hi windwss,

My LIte DAC-AH's photo which duty heavy modifiacetion.

add clock,
add changed e-cap with flim caps in power supply,
changed all box cap to UCC spp caps.
changed outup caps to ERO MKT 10uf/ with MKP 0.1uf/

Thanks.

hi windwss,

sometime listen CD33, sometime listen CD33 with DAC-AH, very enjoy both.

I also have other system:

CD Transport (Audio Alechemly DDR pro)
Diyeden 01 Plus DAC moidified.


Thanks.

viewer,

u now using CD33 with the lite DAC or using CD33 without using DAC?

Abharder,

Try to listen to your ear on your system, it might be different from you thought.....if u 12 try just let me know lah....i got 2tungsol....

Hi WINDWSS,

From what I know tungsol is not a good tube for CDP may be it suitable more for OCTAVE's amp. I still like thw WE's sound or else i will try others if i found Bandit.  :  

Hi Superwhite,

How is my quotation?
Have you work out for me how much shouid i invest over all?
Where else you want to bring me for good Hifi shop?

he..he we still do some modification, especially on power side... as u said modification is fun...n i also enjoy it....

what i worry is that when i keep put in n remove the cap at the same place...the board will damage fast....my board material not very good leh... if the component on the circuit board can plug &play then will be easier : )

so far had change the power coupling cap, a few resistor, the 47uF/160v ecap (last month). last week just change the opa5532 to 2604 and some cap...but found not that nice then cahnge backthe cap n remain 2604.

my problem is that i feel that my sound is more musical n confortable before change to 2604... even though 2604 is much clear n detail...

so no choice i still need to do more modification to obtain the sound i want : )

Anyway must thanks viewer &superwhite who help me a lot in this....

Hi windwss,

I suggect you to use at lease 40% more volts  of e-cap  is better which measured voltage is 115V.  

You  measure the voltage across my 47uF/160V e-cap & found that the measured voltage is 115V, in this case, use 47uf/160v is save.

have you modified it or consider a DAC??????

thanks for sharing.

Ha..ha... yaloh..everyone have his own taste : )
some doubt need u all's advice....

i had measure the voltage across my 47uF/160V e-cap & found that the measured voltage is 115V, in this case do u think a blackgate 47uF/100V e-cap can sustain/work with 115V?

Hi windwss,

I think anyone who have his taste, I will not gave comment on which tube is the best, I only belive my ear.

I think superwhite's  modified cdp is situable his taste.


Just for sharing.

Hi WINDWSS,

:  :  :  :  :  :  :  :  :

Abharder,

If u wish to try the tungsol tube i can lend it to u....don't always WE396A only...ha..ha.. if not later your modification will be same as superwhite...

Don't tell me your taste is exactly same as superwhite....
