Hello,

I would appreciate some design ideas from the brave diyers out there.

I was thinking of using the BB INA103 and or BB INA217 for this design. (may also throw in some OPA627 or OPA2132)

I need the following 5 filters for the design

here are the time constants for the filters :

* 7960 us ( for RIAA / IEC )
* 3180 us
* 318 us
* 75 us
* 3.2 us ( to recover high freq harmonics)

Any ideas and comments are appreciated.
