We should all honor "what the artist intended" without exception. Its a rule. My experience has been that the artist intended for the public to purchase and listen to their music. Full stop. Never seen a single musician refund my money in outrage that that particular frequency must not be corrected.
As much as I hate to admit it, I have a Loki in a tape loop on one of my setups and I’ll be darned if it doesn’t always sound better when called upon than I want to let on. I may use it a couple of times each week but it is better than to not listen to something because it/my system/my room don’t play nice. It always bothers me though and knocks me a bit off balance that I have a couple of thousand dollars of interconnects going to and from this $150 tone control. Oh well, I’ve needed my head examined for some time now.
