I took a chance on the EQ20 (spotted on eBay in what appeared to be excellent condition). This unit is circa 37 year’s old after all so for me to part with £99 could have ended in tears. Fortunately ‘Lady Luck’ was on my side, as apart from the power switch light not illuminating, sonically this Equaliser performs superbly. It also looks stunning and there are no crackles when adjusting the sliders while the low level hum coming from the unit (turned out to be the transformer) was fixed by placing silicone pads under each of the Equaliser’s four feet which eliminated the vibration that was amplifying the noise. The best thing about the Marantz EQ20 is it’s ability to make CD’s sound so much better. This is achieved by lowering the midrange sliders in order to give each CD much more body. In fact, the overpowering midrange of many CD’s is kept in check by the EQ20 allowing a deep, rich sound. I will sort out the power light in the near future and will maybe replace all of the capacitors. If, like me, you prefer vintage hi fi equipment without all the flashing lights, then why not take a closer look at the EQ20?

re: EQ-20

I received this EQ on my 16th b’day in 1984, and it is still going strong all these years later!! The led’s flicker a little when adjusting the sliders but otherwise works perfectly and continues to balance out my music, I wouldn’t be without it!!

re: EQ-20

Edit: l would like to add that l use the Marantz EQ20 in my Cyrus Pre/power amp set up and since there are no tone controls (i.e. bass/treble) l do find this EQ essential as (like many others) l do not have a listening room with ‘perfect’ acoustics or the ‘perfect’ loudspeakers.
