I can not live without "Room Correction"

I got  GAIA isolators today and it changed the tone of my system drastically with tightening bass , more transparent soundstage, better focus and details.

Room correction is one way to control tone of your system.

But other methods also can help.

shkong78, the IsoAcoustic GAIA isolators (and the Townshend Audio Seismic products) address only the speaker they are used with. Addressing the issue of room acoustics is a separate issue, including room dimension-created eigenmodes, reflections, etc. Both speaker enclosure and room related issues can be dealt with if one chooses to do so, but they are completely different issues, addressed by different measures and with different products.

This room is rough, so do what you can.  

You're centered toward the left it looks like?   You have first reflections coming from the glass on the left side of the photo far earlier than the right side glass for sure.
Using an EQ that has various artifacts, to optimize the area the size of a dime?    Our ears are a foot apart. We also might want to move around, or share the room with a friend.
Better to treat the room ... first trap bass, then kill first reflections, then get speakers that work with the volume you have and tune the system to the room. 

I've been a huge fan of Dirac Live since it was first released as computer software several years ago. Even if your room is acoustically perfect, it can address the speaker and electronics to some extent as well. If your room is not perfect, it will have an even bigger impact.

Some of the hardware products are relatively inexpensive, and you can try out the computer software for free.
