Stereo EQ in the hifi world ...?

Every now and then (more often than not) I feel like I want to boost/cut some EQ beyond the capabilities of my amp. I know most purist guys will shy away from EQ ....any suggestions on a great stereo EQ that does not generate too much hiss/noise?

Looking at Technics / SAE etc....
thanks
