EQ before Preamp?

The best place for an EQ would be after the digital out from a CD tranport. I think the Behringer 2496 EQ has a onboard DAC?. I know some people who use that kind of gear together with a mic. to apply some room correction. The correct way of doing this is.
1) have a someone messure the acoustic properties of you room.
2) adjust accordingly with bass traps etc.
3) measure agian
4) make minor adjustments to the trap etc.
5) use your EQ with mic and some pink/white etc noice to mesure your room
6) use your EQ to smooth out the last bits.

If possible don't boost frequencies only dampen freqensies.

Don't use cheap pro gear like Behringer pro gear or if you do modify it.

Pre amps like tact aleardy ahve some of those features build in.

@Eldartford

That is not entirely true I think. Most pro gear is even more expensive then some audiophile brands up to a certain point. A lot of pro gear has to sound good and be able to take a beating. That is why you almost never see real pro's use Beheringer, the build quality is not that good and the sound qulity isn't that good to.

[quite]I agree that capacitors in the signal path can affect sound quality.[/quote]

I am no engineer but wouldn't it be best if there are no capacitors in the signal path. At least my 'cheap' Rotel pre amp doesn't have have any.
