This heresy business is a case of the emperor having no clothes. Of course you may need tone adjustment. Recordings vary widely in how much *they* were equalized (either naturally or artificially). Good recordings tend to sound better on more systems, but even good recordings may not sound right on a given system without some adjustment of the tone. The only problem with equalizers is if they distort or pollute the noise, not the fact of EQ per se. Furthermore, even if you wish to pump up the bass or treble more than the recording engineer intended, that is not necessarily wrong. It's a matter of taste, though many surely overdo it. The fact that so many "audiophiles" evidently shy away from EQ shows how subjective and susceptible to fashion this audiophile business is.
I know this is heresy, but...
I am interested in adding some sort of equalization within my system....tone controls for lack of a better analogy. I know that years ago Audio Control used to make a band equalizer. Anyone out there making that sort of device today? Basically I am looking to add a little more bottom to my system without adding a subwoofer or adding a lot of noise to the sound. Thoughts?
