Hi WINDWSS,

i want better sound, that why i spent some money to buy good component, you dont want after you Built the pre-amp, sound is worse than your AUDIOLAB, then no point to DIY the Pre-amp, also i want to Mod this cd Player to the MAX then only MOD my AUDIOLAB amp........ :wink:

So when you want to MOD your 8000A ? :wink:

Thanks for the diagram, if Tube pre-amp i Prefer to built CV3

hi viewer,

Thank for your info, as i know the MKC is metallized polycarbonate cap, it seems it is more expensive material than polypropene and have good electronics characteristic but i'm not sure good for audio use or not as i since most people like to use polypropene cap. MKP or MKS is the replacement for MKC as MKC no longer manufactured.... but i'm just thinking some manufacturer sometimes stop production of some product is to reduce cost with reduce a bit the quality. So sometimes latest version may not be better.... so in audio u think poly propene or polycarbonate is better?

Superwhite,

Ha... i not so ambitius and willing to spend like you... thus i look for other alternative way to look for parts loh.... by the way u 12 DIY a tube preamp not i got a DIY diagram using 6n3 & 6N11.....

Ah forget to tell u that i got some info on modify audilab 8000A which is to seperate the pre & power of the 8000A.....

Hi Superwhite,

vishay or vishay BC Component for ecap are good (euro sound) warm and sweet.

Hi Windwss,

My Das is using a lot of RIFA PHE 428 caps, the high notes is clear (good).
I have no use Wima MKC4 before, so no comment on it.
But I used Wima MKP10 and Wima Black Box before. RIFA PHE 428 same of Wima MKP10.
Since Wima MKP10 is high grade than MKC4 so RIFA PHE 428 may be better than MKC4. I think.


Thanks for sharing.

How feeling of tube Western Electric W396A ???
Is it are using in you cd33 ???
have you used RCA 5670 before and the felling ????
because in other web site is on sale around HK$120.00 pair.


Thanks you very much.[/quote]

Hi viewer,

BUY IT! good deal!   WE396A is a musical tube, Fast, the bass is stronger, compare to 5670 tube. you won't regret. even if you DONT wan , is very easy to sell off :wink: .



WINDWSS is using GE5670, i also bring 1 unit WE396A to him for testing, he also notice the diferrent, i think if put on your Jensen copper sound will be much better. [/quote]

Hi Viewer & superwhite,

Intially when i change my 6N3J to GE jan5670w, feel that GE sound very sweet, warm & nice but a bit slow & not so detail --> good for vocal but bass less tight, musical instrument also less excited. Since i prefer intrument like drum and so on, thus i some time change back to 6N3J when listen to musical instrumnet then back to GE when vocal.... Generally i will say WE 396 is overall good, sweet with detail thus no need to always change tube while listen to different song/music. compare the GE, WE396 is less warm & sweet but more detail, faster. GE tube construct is a way that it reduce the detail in order to give very warm & sweet sound.....

Hi viewer and superwhite,

Actually there are another alternative instead of making a black paper disc use on the CD, if u have old disket, open it and take the black manegtic thin sheet inside. it will give similar effect and much more easier than make it, nowaday most of the disket is 3.5inch, if u can get the 5.25inch one will be bettre as the size similar as the CD. But becareful, must remove thorougly the glue if not it may stick on the player tray.

The main fuction to to reduce vibration so sound stage become clear, less noice. If u willing to spend then can just buy this type of damping mat but not cheap loh....

Viewer,
Need some advise from you, do you think evox-rifa cap is better or wima (MKC4)is better or RIFA PHE 428? If use for tube coupling cap...


superwhite,

I now so aggresive as u thus i now ask friend around to get me some un-use circuit board n try to retreat useful cap. A lot medical equipment is using cap such as rifa, wima, nichikon n so on. Anybody heard of ERO cap (KP 1836 E5)? good or not?

What is the difference between OPA627AM and OPA627bp?

My Shanling T80 has 3 OPA2604, I've recently replaced 1 OPA2604 with 2XOPA627AM + adaptor.  The player sounds warmer than before.

Just wonder whether changing the other 2 will give extra improvement, but quite expensive.

hi, superwhite,

FK's size is tall than FC is standard acuatlly as same.
Of cours, BG standard is better than panasonic cap FX and FC. but BG std also very expensive.

If you diy shop provide the  Pureism and X-Pro series Capacitor is made by Panasonic Electronic specially for Audio, that the sound quality same sd BG std, it is cheap than BG std.
up to you.

Thank you both of you for the advice and guidance.....i will try to do mare practise before start soldering on teh board....

Superwhite,

will ask your help when all teh tools ready.....

For your speaker, try seperate and twist your internal cable in speaker 1st, if possible replace the white sponge to the yelow fibre sponge which people use in exzos pipe..... with this 2 trick most speaker will have better detail,sound stage, less quantity but tightter bass and more transparent...

After u do the above trick, u may not get the best sound immediately, it will take several day for it to stable as the spong will need time to adjust it spacing.....

from my experience every time after i adjsut the amount of fibre spong n positing on sand bag in my AE AEGIS it will take several day to stable down... thus initially the sound may not good....  it is quite time consuming unless u enjoy testing....

for speaker cable u may look for 7n single crystal loh.... i'm not as ambitius as u, i'm satisfy with my own make CAT5 cable....except my interconnect....

In my point, if you change copper oil the speed will slow a little, but very match you cdp 33 Map cap outup supreme siliver oil (speed and clear)
copper oil will add a warm and more bass. It must be run 300 hours.

50v replace 25v is ok it will be better than 25v.
advantage can accept votage up to 50V and lower lost on singal.
disadvantage is the sound speed will be lower.
audionote caps is same as jensen cap, because jensen is oem for audionote.
but the price is lower than audionote.

You said replace siliver cableand inter connect, I think in you cpd will to fast, the sound will be to clear. This is my mind. copper is better.

Thank you for sharing.[/quote]


Hi Viewer,

Thanks for your info, it really help :wink:

not the interconnect, but speaker cable, i found it not suitable for my ear, too sharp, ofcause this cable have more DETAIL n CLEAR compare to my previous cable, is it need to run for long period? will try to get the 7N UPOCC cable n  try it :wink:
