EQ for hifi stereo


Is there a product that can be use with a stereo system: amp Moon W5 LE/ preamp  LS 26/ CD Player Moon Supernova/ and turntable use as room correction and also EQ ?  Will it harm the music presentation as definition: stamp of instrument, holographique music scene presentation ?  Have you try some of these components ?

I just ranted about the Loki on another thread (right next to this one), and it's a serious little "do no harm" EQ that may be all you need. I really like the thing. I put mine between the preamp and power amp.

N80, most eqs I am familiar with have bypass capability. Refer to the thread indicated by lak.  Enjoy ! MrD.
