Who does make excellent EQUALIZERS???

I'm using a Rane ME60 in one of my systems, and I'm happy with it. It has 30 sliders per channel for 1/3-octave control. I hear no sound quality degradation, although I know all equalizers will theoretically have adverse effects. It has better build quality than an Audio Control 10-III I used in the past, although that was a much less expensive product. The ME60 was reviewed favorably in The Sensible Sound late in 2000. At the time I bought it, I also considered the Cello Palette, introduced in 1985 by Mark Levinson. While the Palette is a true high end product, it had fewer bands than the Rane (which comes across as more of a professional/industrial item). By the way, Mark's current brand, Red Rose Music, currently offers an equalizer that operates in the digital domain. It doesn't seem to accept analog signals and is intended to fit between a digital transport and DAC. See it on www.redrosemusic.com. Good luck!

I am using the Accuphase DG-28 equalizer. It works in the digital domain - no signal degradation.Control is 1/6 octave.Can be adjusted manually, or using their algorhythms.
You can measure your room reponse with a supplied microphone.
It puts out a signal through your speakers that is then measured and corrected. It really works, especially in the bass.

Hi Herv,
it largely depends from the level of your front-end; a good choice was the old Technics, parametric, slim line series SH 9010 or similar...
If you have a good front end, the only one is CELLO Audio Palette; but is it strictly neccessary?

Z-Systems RDQ-1 or RDP-1.

Other than above Accuphase made a two channel EQ awhile back with 31 bands per channel - it had a great look - I think there is one for sale on Ebay.
