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 ?

You can put the LOKI either in-between your source and preamp or between your preamp and power amp so it can be used with all sources.
While implied, it works great ahead of any integrated, analog input.
