I suggest looking into the Pioneer SG-90 as an EQ upgrade. (10 band EQ units are a poor design approach) The SG-90 is all discrete transistor in its EQ section, and is extremely quiet and natural sounding. So there is not as much harmonic distortion multiplied as we have in a 10 band, whose iso centers are in octaves and multiply harmonic distortion. It is a 17 band EQ, all centers are not octave multiples. The finest graphic EQ for home hi fi use I have ever heard is the Pioneer SG-90. But, in almost all cases, the bad just does not justify the good.Ī parametric EQ is beneficial for dialing out resonances, such as a bright vowel sound (ie: a high pitched "i" or "e") The graphic EQ can not correct this. even if we feel (temporarily) we've struck gold in an EQ setting. You'll get phase coloration, and increased harmonic distortion, added harshness. Unfortunately, most hifi for home use EQ units are not very good. probably the most hated consequence of dialing in too much EQ. In fact, the EQ unit itself introduces phase coloration. Speaker crossovers, (not well engineered) can introduce massive phase coloration. Sometimes a dissatisfied listener may try to EQ out something that's annoying. Again, to EQ a mixed finished product can be an effort of frustration. The vocal is affected by instrument timbre and level. A vocal may not mix well, or "recede" with guitars too bright, or muddy up with a heavy bass line, etc. A great sounding vocal may sound fantastic by itself, but has to mix well with instruments. Can you imagine how tough is is to EQ a mix? It's tough enough when you have separate tracks to work with.

This is more art than science, IMO, but does require acquired knowledge and a trained ear. In the studio, the sound engineer may have a tough time to get the individual tracks to merge, yet also remain discrete and identifiable.

So when adjusting a guitar for more bite, or a snare with a nice crisp attack, we can then cause the cymbal to sound glaring and harsh, or maybe vocals become too sibilant and edgy. Even the casual listener may prefer percussion and bass, and respond to that, or maybe melody or harmony! It's actually the exception a person listens to a song as a whole. The human experience in listening to music largely focuses on one instrument, guitars, drumming, maybe the shimmer of a cymbal or maybe the lead vocal, especially when listening more critically. since additional EQ can mess up something else we are not listening to. I have found from experience, and going through the same frustrations, that a mediocre recording mostly sounds better as is.

EQ can help a not so great recording, but this is more the exception than the rule. Click to expand.Voice is challenging! When EQ adjustment does not seem to lock in to a magical sound, then something else is wrong.
