So you revitalized this thread ---

I have news too. I tried the LME49710 (the single version of the 4652) and it is indeed very, very good. Practically, you get the fastness and bandwith as with say the AD797, combined with the robustness and non-pickyness of say the op27. Makes it a good choice for voltage regs as well.
Subjectivly it is a winner, it sounds so great. This in a eq-stage of a phonopre.

I happen to have build calvin's circuit yesterday night. First listening test confirms it is very, very good. Differences with two different discrete fet input circuits are subtle, and that means (according to me *cough, cough* ), that the ina103, being the first stage, is a great chip, and the overall circuit is very well designed.

Hi Mooly!

I found this thread and was interested in this comment. Could you please be more specific as to the connections of the cap(s)?
