I use that kind of decoupling too. Usually 220uF and 22 Ohm. The 0.1uF straight over the supply pins i found first at Douglas Self.

Nice papers thanks..🙂

This is what we did to prevent oscillation in the high impedance mirrors of the paradise..

O.k. I posted this in the builder thread, I should have posted it here, sorry 🙂

And if you have some spare time, go-to Google.com (yes that one 🙂). In the search-bar type the name of your favorite component (BD140? or (as I did here) LME49710). Then select 'Images' and be amazed 🙂. Looking at these images you see odd items (or just interesting ones), select one and have a look.

BTW this is what I found in the LME49710 search results opamp??

 

[Joachim Gerhard]

I will look that up.

There is a ton of good information in the http://cds.linear.com/docs/Datasheet/lt1115fa.pdf datasheet.

Yes there is, but several local DIYers here have asked me for help for the reason that a phono preamp built according to the datasheet was oscillating. LT1115 may behave tricky, especially with additional buffer in the loop. So is AD797.

Are you refering to the paradise ?

If so what opamp do you suggest for the servo ?

No, I was referring to the datasheet that FDW has linked here, i.e.
http://cds.linear.com/docs/Datasheet/lt1115fa.pdf
There is a schematic of phono preamp with LT1115 and I was referring to that.

Regarding paradise, I have a feedback of one local DIYer here and yes, he says it is oscillating. But it is just one piece, no statistics available to me regarding paradise.

For servos, I use OP07, OP177 and OPA134.

Yes, the LT1115 can be a bit tricky.

Ohh... now room correction for headphones... I wonder if that will give you headache.
OK to bypass and fool human psychoacoustic capabilities must be a quite a challenge... honestly why bother... ??

I hear this smyth realizer in 2011 and I was really amazed. http://www.smyth-realiser.fr/
It could really emulate the sound of the speakers in the room throu the headphones... so it is possible
