Stereo EQ in the hifi world ...?

Note that the 20Hz and 8kHz knobs have a +/-12 db range and the 400hz and 2kHz middle knobs have a +/-6 db range...I think the 8kHz sweep covers the treble edginess issue just fine (each eq range is centered but gets fairly wide as you increase or decrease it), and the sort of tapered response of "more first and less later" is interesting and really does the job.

Thanks wolf, very nice explanation. I'm not sure what the freq. range of the objectionable mid-high to high of these digital pressings are. Perhaps in the 5kHz to 8k?  I wonder if there has ever been testing done.

It's sad so many classical recordings were ruined for eternity by record labels and engineers during that time period.
 

I'm also curious to see how an external EQ can improve brand new CDs that tend to be loud and have compressed DR. I find that it is the mid-high and high frequencies in these as well that bother me. For $129 it might be worth it just to find out.

An example of Loki usefulness is illustrated by one of my fave albums from the 70s, Little Feat's "The Last Record Album." Lacks sparkle for some reason, but boosting via the Loki 8kHz frequencies just makes it shine...

@wolf_garcia , can I assume you are using cables of equal quality into and out of the Loki?
