Unbalaced to balanced input transformer

[Mallard]

Hi there,

this is my first thread here in this forum. It seems to me that this
forum will be quite an excellent source of informations for my
future SOZ project (more about it in another thread). And here is
my first question:
The origin SOZ design has a balanced input, but my CD-Player
unfortunately has only an unbalanced source. I found a good
answer to this question on the Jensen-Transforer page. They
recommend to use an input transformer, this would be the best
solution for that. Is this true? Has anyone made experiences with
that?
It would be great if someone can give me a hint!


Thanks in advance!

Easy.

Just ground the "cold" (negative) signal on the input and connect your CD to "hot" (positive) input and ground.

The SOZ isn´t that happy with unbalanced input, I have tried it.
You did visit Jensen-Transformers homepage, and that´s why I remembered this nice and informative discussion here:
Balanced line

So, what is the problem for you using the unbalanced input?

I've tried it, works fine.

You could build a BOSOZ pre amp, or something like it. Then you'll have balanced output. Simple and pretty cheap.

Shure it works, but you will get more distortion (not so perfect diffrential match), less gain and you also get some lower max. voltage swing at the output. SOZ does not have a Constant Current Source at the tail, if it had it woud be a better converter.
I agree that the BOSOZ would take care of thet and reasonable prised too.

Sorry I dont wanted to raise up such a big thread as you linked to. My Question is quite simple, I don't want to hear physical definitions and theorys.
Btw I don't know how much of it reflects only superstition.
Basically I only want to know what's the best choise for me in regard to how it sounds at the end! Thats all!

Thanks and Regards,
