Should Equalizers make a comeback?

I owned amps years ago which, indeed, had balance and tone controls but these were single button controllers which allow only for adjustment of both channels together. For control of the kind that one needs for accommodating room acoustics or, in cases like mine, hearing deficiencies, more latitude is needed especially for adjustment of relatively specific frequencies for each channel independently. I'm writing, btw, in reference to the use of graphic equalizers in two channel applications as this is the only experience I have.

I'm currently using (digital parametric) EQ in an active, tri-amped setup. While no EQ has zero negative influence on the sound, I usually find that the sonic advantages very often outweigh the sonic disadvantages...and below roughly a 100hz or so those sonic disadvantages seem to evaporate.

I enjoyed ths lights...lol.But I did like using it to play around with ,and toy with the sound.

I just picked up the RME adi-2 DAC and it has a great 5 band PEQ, tone controls, and loudness.    I usually run it no EQ and it sounds great but at lower volume and non critical listening the Loudness contour is  awesome. It is adjustable too with respect to dB level for bass and treble and the point on the volume scale that it tapers off.   

This DAC is incredible for the money 

Maybe it's the quality of tone controls or EQ.  Every studio uses EQ during the recording, mix and mastering.
