Default Equalize or Not Equilize when driving a tube amp ?

I got bit by the tube bug when I bought my first MiniWatt N3. The little amp has a permanent home in the bedroom driving a pair of Energy CB-20 speakers. I get to listen to it often. Now it's time to upgrade the sound system in the living room. I've got an old Kenwood KR 350. I've had it since I was in my early twenties. Now I'm upgrading with a Jolida 202s. I plan on using the pre out so I can connect the kenwood and still use the tuner and Techics turntable without buying a preamp right away. I'll directtly connect my Ipod to the Aux input, any equalization will be done on the ipod, that's what I do now. I've got an old 10 band Realistic Graphic Equalizer that has worked well with the Kenwood Amp. Have any of you fed the Main out from the equilizer to a line in of a tube amp ? Main Out = Line out but I was wondering if I was just better off with no EQ in the loop.
Eventually I'll just have the Ipod, Turntable (connected with a tube based phono preamp) , and eventually a HD Radio will take the Kenwoods place

I'm hooked on the soundstage and detail that you can easily hear with a tube based amp. Do you loose anything when you add an equalizer ?

I believe that if the audio levels and impedances are comparable between them, there mustnīt be any trouble. Looking into the amplifier from the input terminals, tube or not tube amplifiers are almost equal.

I'm a purist so I would say try it without and if the sound is really not to your liking then add the EQ.. Note also that you have probably become used to the way it sounds Eq'd so it might take some fiddling with speaker placement and time for you to like the unequalized sound.
