Give some consideration to the following pro audio oriented tubed EQs
D.W. Fearn VT-4 -- it's mono, you'll need two
SPL Qure
Tube Tech EQ-1 -- it's mono
Drawmer 1961
Millennia NSEQ -- has both tube and solid state EQ
Manley Massive Passive
All of the above are built to audiophile quality standards and will allow you tremendous flexibility in how you can shape your system's sound. Unfortunately, they only offer up to 4 bands of EQ and can't match my McIntosh 8 band. Mine will still be bigger than yours!
Seriously, I do find it a little strange that you want your digital source to match the frequency and dynamically limited performance of your FM. If that's really what you want to do, then you might want to reconsider how you put your system together. It could be that you're not a high powered solid state kind of guy?
