what is the use of a Calvin Buffer? Sorry for my ignorance. I looked in the buffer's thread but I didn't get it

My 700+700 Bc ( plus the difference to 50 euros the minimum value for the order - a ERSA RSD 80) are on their way. To me. Are anyone using the Ersa RSD 80? I have been using some ERSA equipment and I'm content with it.

the calvin buffer can replace the onboard buffer, and has much stronger drive capabilities, sounds clearer and more detailed. The onboard buffer is very good, but this one is better especially when the line stage has low input impedance or long cables are used. It sounds clearer and more transparent, in my opinion.

does anybody know of a discrete output stage that at the same time does convert SE -> BAL? I would like balanced output since my amp is balanced input. Of course i could run it through a transformer, but that feels like the wrong way of doing it.

I think you can use a chip from That Corporation.
It sounds very good :

Thanks for the tip Joachim, but i would perfer any discrete solution, because i tend to think that IC's sound quite dull. Of course it would be possibly to try that IC, but then i could probably just use a transformer (which i already have).
I was just thinking if there was anybody sitting on a discrete se->bal driver stage design that could be used. Not for gain, but rather one less stage to add distortion.

Hi,

just add a differential stage ahead of two buffers, or..
add an inverter ahead of one of the two buffers.

Would you have a suggestion for a differential stage with a gain of 1? I kind of have the same issue.....
