whats the best addition u have bought for system

The best addition I have made to my system was buying a Pair of SP Technology speakers.

Evaluate your listening enviorment and begin educating yourself about room treatments. I recently moved into a dedicated listening room and the addition of GIK room treatments and Echobusters in the ceiling corners make BY FAR a bigger difference than any single piece of gear. Go to their websites and that will get you started. The untreated room is reflective with a confused soundstage and is harsh to the point of being unlistenable. The treated enviornment has brought the musicians into the room for a listening experience I find difficult to pull myself away from. The frequency range is balanced, soundstage wide and deep, yet precise. NO harshness just natural sounding music that I can enjoy for hours. The importance of room treatments cannot be overstated, only after that you will be able to truly appreciate any equipment upgrades you make. Good luck and remember to have fun.

Start smart with a good foundation and install some dedicated lines.

Boom box sounds like a better description of an untreated room than the one I gave you in the above response. Do yourself a favor and contact gikacoustics.com. Tame the room reflections or any money you spend will be wasted.
