Go get out your pitchforks, I’ve done a sacrilegious thing. . .

I guess I don't get it, equalizing system vs equalizing the recording. I don't need to equalize my system as it's voiced to my preference, the recordings another issue entirely.

I can't understand having this tool and then not using it for the greatest variable in one's system, the recording. As with some previous posters, it would drive me crazy having this tool to adjust for every recording, and not using it in this manner would make it worthless to me.

I don't know about others, but there is no way I'd go down the path of changing settings for different recordings. Who'd even give it thought?

Like some here have suggested you should have done several things before you tried the eq. First off, I would suggest demolishing one end of your house, then rebuild a room with soundproof double walls for a dedicated audio room with top notch wiring and electrical outlets, don't forget power conditioning. Then self flog for buying a house that didn't have the acoustically perfect room. The next step is to plaster all the rooms in your house, including your bathroom with sound absorption  panels. After this, self flog again. Now if no perfect sound from your audio rig, add hearing aids. Another self flog. The last step is the EQ.

Hey, if you’ve voiced your system and there is zero room for improving it or the room then I guess you’re lucky and will never need to upgrade. However, I’ve never been able to achieve perfection, but I got a whole lot closer with one component - go figure! And it only took 5 min.

also for those talking about adjusting for ever song, do you change out cables or equipment for every song?  You know you can just adjust it for best overall sound and forget it. Very easy!

My 2 cents on readjusting the EQ for different recordings - I've had little luck with that. I consider that a good thing. When I get the system response correct pretty much everything sounds better.
