I'm sorry to answer in advance with a counter-question; is the sound with this amplifier so bad that you need an equaliser? In that case, I wouldn't buy it, because I'm looking for an integrated amplifier that doesn't need an EQ (they always change the sound). In principle, however, it is possible to connect the equaliser with the same cables.

What kind of source (CD player, radio, mobile phone) should the sound come from? In my opinion, it should be possible to hang the EQ between the output device and the amplifier?
