I have an extensive DVD collection. I also have had to remove the HDCP copyright protection from them, as it is incompatible with my LCD Projector, and makes the DVD's drop to 480P from 1080i. I have a DVD player that was sold illegally in this country. By flashing the unit's firm ware, I was able to convert it (it said Zenith on the outside) to L.G. on the Logo, and pass the high definition signal through the YPrB RCA jacks. Since this DVD player has a built in upscaling,(to 1080i), I am able to watch movies at 200" inches diagonally, the picture is rear excellent picture. I make my own speakers. I designed a pair of tapered 1/4 wave tubes for the front left and right main speakers, with an Fs of 29 Hz. These are 6.5' feet tall, 14 inches wide, twelve inches deep at the base, with a 3" port at the bottom, 14 inches long for the base rear wave to come out in phase with the front wave. They do not vibrate as they are an open baffle design. I used a Piezo electric tweeter as they produce a capacitance feedback, which precludes the need for a cross over network. The have a very Holographic sound. Two Infinity speakers for the side, and two vintage Genesis II speakers bring up the rear. I have a Miller Kreisel sub-woofer, it goes down to 10 Hz.
For audio, a way different approach. i have a LL Scot LC290 Laboratory Tube AMP, circa 1960, (12AX7's)with matching tube pre-amplifiifier, and tube FM Tuner. Musical Sound with Vocals, to me is a very different experience than sound effects. My Onkoyo 7.2 receiver works fine, but just does not compare to the tube amp with simple stereo, and vintage vinyl.
