Absolutely, agree with Stereo5 above. In fact, those improvements did occur when I placed a Shunyata Hydra 2 (and later a Hydra 8) in my system, including having the DVD player (now a Blu-ray player) and also the TV attached. The picture was more 3D/holographic and color saturation improved so much that I had to adjust the color saturation downward.
Sound will improve also.
