Hi Ralf

Your pictures express very good systematic arrangement.
I suppose the sound must be great too.
In addition, your speaker cable attracts me. DIY? What kind?

JH

thank you,

the speaker cable is also diy and extremely good, but it takes very much time -and blisters to make. i found hardly a cable which was better.

you get informations at http://www.venhaus1.com/diycatfivecables.html


regards,
Ralf

Hi NP, jh6you, Henrik, ralf and all



Thanks for all the sharing. I have learn alot from you guys. 🙂


I intend to build jh6you version of XBSOZ and have a few questions. I am not electrically trained, please forgive me if my questions are too ignorant.

1. Is it ok if I use 2 number of 2x18v, 60va instead of 2x30v?

2. If I would like to increase the regulated voltage to 40v, would I need to change any of the value in the circuits?

Thanks in advance

Cheers

1. ..should work

2...i think you need one zener more to get about 40 V



but why do you want to go to 40V?

Caps experience

..as i told you that in my new X the sound does not come exactly in the middle...

i reversed the two caps ,which were build-in other way round and the soundstage is homogenious and singers are exactly placed in teh center - if the source tells that.

if i didnt make this experience i would`nt believe.
I never will reverse caps in signal path and elsewhere...unbelievable.... :bigeyes:
but true.

regards,
Ralf
 
Didn't I tell you?:spin:

Now, Henrik, it seems like you are really into it too. I checked again my caps and it appears that both of my paralleled caps have the outer foil facing the load (amp's input). When I mixed inner with outer on both caps it didn't sound good, also both outer foils facing the preamp didn't sound well. On Aleph X the cap connecting negative input with the ground also affects the sonics the same way as the other cap.

Michel Percy also recommends to orient the caps with outer foil towards the load.
 
Ralf and Peter:
The caps move the position of singers to the center...?!?!

CH2:
One more 9.1V zener is necessary as Ralf commented. The increased regulated 40V
will help for less distortion in sound as Mr Nelsen Pass indicated.

jh6you ,

since my english is not the best i can hardly explain that.
as you see in the pics of my XBosoz, the 33uF are realized with paralleling 5 6,8Uf MKP`s.
While i solderd them i did`nt recognize that i soldered two of them other way round, but i thought it woulnt matter.

In my listening tests i went with the chair to the left, because somehow the sound was moved to the richt channel, which i solded correct.

First i thought i should regulate down the richt channel input with a pot, but then i tried to correct the two Capacitors.

So i soldered the out turned them and listened again:
All is perfect now, the chair is in the center.

DONT ask me why, thats a strange experience for me, too.

220uF capacitors in X Soz

Hi, this weekend i tested different MKP`s adding to the 220uF electrolytics.

although, Henrik told it wouldn`t matter, about the quality of this cap, because it is in the loop, i can tell, that there is a hearable difference, even they are soldered in other way round. The result is smoother without loosing details.

I also connected my Hiraga Le Monstre this weekend, and can say, that XSOZ with XBsoz now beats the hiarags in better 3 dimensional sound stage and resolution.

the same thing in the coupling capacitors of Xbsoz!

Problem is the price of high quality caps in the XSOZ and XBsoz loop.

How is the stadium of your`s , Hendrik?

Hi Ralf

What I ment was, that even if the 220uF cap is crappy, the X sounds way better without the buffer made with high quality cap.
http://www.diyaudio.com/forums/showthread.php?s=&threadid=3949&pagenumber=17

At the moment I am rebuilding my XBOSOZ with:
Audionote 1W Tanalresistors
Holco MP930 powerresistors
47uF Blackgate BG-N

Also, I have bought some 220uF BG-N for my XSOZ.

I think I will finish XBSOZ and XSOZ in late december, I hope.
Meanwhile I will send some pictures.

Nice knowing we have beaten "le mostre"
 
Hi guys

I have a plan to make a new attenuator volume for my unbalanced-balanced converter pre, BOSOZ. In this area where I live, however, I hardly find audiophile-grade of rotary switches of 2x11 or 2x24. Even if I find them, the prices are not a joke. Meanwhile, I can easily get reliable quality of cheap rotary switches of 2x6. Therefore, I am thinking to use two sets of 2x6 rotary switches to make my new attenuator volume.

The following drawing and diagram are self-explanatory. By the way, if you foresee any problem or have any better idea, could I share it? Thanks.

jh6you,

the pot(24 stage) in my pics of xbsoz above costed 50$, and they are really good quality, but i dont know if they are availlable outside germany.
i bought it by www.steinmusic.de (english translation ist o.k)
I think he sells overseas.


But Question: (Henrik)

since i have XBSOZ and put my pot in the output of XBSOZ, there is a kracking by turning the knob, which wasn`t with my Bosoz.

Can anyone explain, why?

Ralf
 
Ralf

My pot is at the input, and that is for a reason.
Vol. pot at the output of the XBSOZ is not a very god idear because it will affect the outimpedance of the XBSOS when it is turned down and thus lover the highend rolloff at the XSOZ. The XSOZ is very sensitive to changes in impedance. You shoud try it at the input.
If You usese one at the output, then it shoud have a very low value, say 200 Ohm or so, it´s a guess since I haven´t calculated it.

The noice from Your attenuater could be some DC level, and it may also be solved if it´s at the input.
