The idea with the power supply is that i do not use a plus-minus supply but only one voltage. Still this stage is mostly DC coupled.
I have not tried it but it could work on the Paradise.
To try that you have to cut the earth trace from Frans Shunt PSU.
I found that the sound improved when there is no earth connection from the PSU.
It is then floating.
I also have another good news. Hesener will make a small PCB for the Calvin buffer that goes into the Paradise. So step by step we are improving the Paradise.

Ricardo, when you cut that trace it is at your own risk. As i said, i did not try this on the Paradise.

Good news indeed JG.

All 🙂, when you cut that trace it is at your own risk. As i said, i did not try this on the Paradise.

And I will not give any guaranties on the usages of the two shunt PSU's (plus and minus) in series with no ground connection.

 

[Joachim Gerhard]

No, it will not.
Actually in the commercial stage i use a different PSU structure.
OK, guys, do not do this.

 

[Joachim Gerhard]

Calvins buffer is an improvement though.

Here are some pictures of the presentation at Bauer Audio.
You see Stig Björge, Jonathan Carr, Martina Schöner, Willibald Bauer and me.
The speakers are prototypes.
Pictures of the Etna soon.

 

[FdW]

Joachim, you are so dynamic in that last picture, you are almost a blur 🙂

 

[brianco]

The room is much too tidy😉

 

[jackinnj]

You see Stig Björge,

"Top Gear" fans will want to know if that's the "real" Stig 😀

 

[jacco vermeulen]

Original Top Gear fans only wish to know the funeral date of the unsavory redhead.

 

[Joachim Gerhard]

Yes, that is Stig from Lyra.
Sure, i am moving fast.

 

[Joachim Gerhard]

The Etna, xover of the prototype, Stig, Jonathan and Willi.

 

[Joachim Gerhard]

some closeups....

 

[Joachim Gerhard]

something different :

[AVWERK]

So this new Etna is a budget version of the Atlas for the rest of us right?😀

 

[Joachim Gerhard]

well, not exactly budget. It will eventually substitute the Titan i .
