EQ before Preamp?

Definately after the preamp & then into the trash. Why would you want an equalizer? It will rob your system of its best abilities: detail, transparency, sparation, etc. and inject more distortion and noise. You know if you can eventually pull it off I would suggest a fairly new Mcintosh preamp with tone controls. It is designed that when its tone controls are set at 0db they are truly out of the signal path for critical listening. Another pre that comes to mind that accomplishes the same thing but is less expensive is the Halo P3 preamp.

I prefer the sound of an EQ.

Thanks for the responses. In this system I will be using one source (Linn Kremlin Tuner).

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.

Mordante...A deep dark secret..."Pro gear" is made with the same circuitry and electronics parts as audiophile gear. It's "cheap" because it is produced in greater volume, and is sold to serious audio people who care more about the sound than a prestigious brand name.
