I need some help or perhaps just some common sense. I am in the process of upgrading my A/V system. Have ordered the Panasonic VT-50, and have received an Oppo BDP 93 universal player. I am seriously considering the SC-61, but perhaps I should get the more expensive ($500.) SC-65. Most of the use of my system is TV or DVD watching or streaming video. I listen to music but usually just as background. The important difference between the two (for me) is the ability to pass 4k. Is this worth $500 at this point in time?
