The current mode approach, maybe i am to stupid to explain that a transimpedance RIAA just does that.

I certainly do not have a problem to judge a design by listening alone and i have a panel of famous and experienced people that i trust.
Take the Calvin Buffer for example. It measures better and it sounds better.
What you also have to consider is that in the Paradise and Masterpiece we use CONSTANT CURRENT to supply the RIAA. That way dielectric absorption and ESR really do not play a big role. The impedance of the mirrors is so high that impedance changes in the caps are swapped. I call that a big advantage. What i think is audible is the mechanical design of the cap and V-Caps may have an advantage there or not.
I also said before that a GOOD sounding amplifier that measures not optimum may simply hide flaws in the recording. You only know better when you have heard true transparency.
Don't want to continue this subject on this 3d as I don't want to spam it more with useless crap...maybe one day we can open up a dedicated 3d and do a shoot out of cap or wires or other foolish audiophiles fetish and maybe you can have fun finding a justification for the different sounds!

If you don't like my post you have no rights to attack me!!
So one more time chill out!!!
Hi Stefano,
you know i know everything you did to promote those caps.
I believe you have no financial interest in this case.
I did not attack you.
On the other hand,
until now the response of those who bought theese little creeps
are not as enthusiastic as expected.
The only thing i've asked for was;
allmost everybody on any paradise-thread had to read constantly
about theese thigies, boring.
I do not think they fit to everybodys taste in every circuit.

I know this is going to expose once more how little I understand but I need to ask anyways - whats the input impedance of the paradise without resistors in parallel?

Reason for my question is I am going to implement a rotary switch for input resisors and I'm trying to figure out how high values work. E.g. there are Grados that work best around 47k. At this point the input impedance of the circuit probably becomes a factor?

Thanks
Sven

It is about 10kOhm. Paradise is really made for MCs. In my opinion, you should not run it without input resistors, and my estimate fo the highest input resistor you should put is probably around 3...4k. But I hope Joachim can shed a little bit more light on this subject....

Alfred, this is correct.
A BJT input like in the Paradise does not have a very high input impedance as is possible with Fets.

What response have you seen that I didn't?
Please link them as the only feedback I got so far was only this one and seemed to be fairly positive.

My Paradise Boards are here!! They look amazing and I want to give a special thanx to Hesener for doing all the work, to give us such a wonderfull product!!
Now we have a look how to implement the Calvin Buffers onto the Board :-)
