@ellajeanelle Your complaint about noisy EQ is justifiable by your comment that you’ve tried many 31-band and graphic EQs. Graphic EQs are the worst! They were designed for live sound where you need to get quick control of a room, but all those bands of narrow EQ each add noise, and phase issues.
What you want for fidelity is a studio EQ with a few bands of wide-Q for minimal phase shift. If possible, you also want ganged controls, so that you only adjust one knob for both channels. Adjusting L & R channels separately is not only a drag, but difficult to keep balanced. @tlcocks is a big fan of the Charter Oak PEQ and I’ve had great luck with the Skyline M3D. There are others, but with studio EQs, you will not get the noise that you get with 15+ band graphic EQs.
@tlcocks Til now, I didn’t know about the Hendyamps Michelangelo, but it sure looks compelling! And the same price as the new McIntosh. With 8 bands, the Mac gives you far more control of the low end, but I’d bet the highs are sweeter with the tube EQ & air band control. There's a Sound On Sound review that says this EQ has a bit of "character" which is desirable in the studio when mixing. Maybe not the best choice for a playback system however.
