Sorry for this long rant but I feel a rebuttal is necessary.

1. Back in the 90's you had 480 I video and 16/44 or dolby 2.1 analog audio. Then the sound was crap as was the video so you could get away with a crappy setup. Now we have 1080P video and 24/96 5.1 audio to reproduce. Thus, one can  obtain significantly better sound and picture if one has the proper system.

2. I don't know about others, but when I go to a concert I do not wear blinders or have Sonex behind my ears to block out the visual and hall reflections which make up anywhere from 20 to possibly 80% of the sound you are perceiving in a great concert venue. I try to sit as centered as possible in the front third of the hall where the sonics are the best and I can view the way the artists are performing, not just hear them.

3. Thus I try to reproduce that concert hall experience as closely as possible. Using a small television set with large 2 channel speakers would be the equivalent of seeing the orchestra from the back of the second balcony with the sound equivalent of being in an open area with the natural hall reverberance mixed into the front soundstage. 

4. With the 5.1 channel 24/96 1080P well engineered concert discs now on BluRay coming out of Europe, at least one gets a sense aurally of whast it is like to be in the concert hall. While I* agree that most of the visuals annoyingly flit from player to player rather than keeping the visual feel that one is sitting in one seat, at least the audio on the best gives me the sound that the conductor is hearing, possiblyb the best seat in the house.

5. We all hear and perceive sound differently depending on our audio upbringing and genetics. I have a friend who finds stereo annoying as he has difficulty integrating a solid image from stereo. Thus he prefers listening to his stereo system from another room. I can just remember the arguments back in the 50's over mono vs. stereo and how stereo would forever muck up the sound. 
   Most of us came up in the mono to stereo era and became accustomed to the inherent imaging distortion of having the hall sound mixed in with the two front channels. I prefer to have it placed where it belongs; around me through the use of surround channels. Others will prefer to keep it in front changing the sound emanating directly from ther musicians.

6. When I  go to see a movie at a theater, I want the best image and sound possible without overloading my senses. Thus I sit as close to the center of the hall as possible with the screen filling my visual field. Unhappily, 90% of the time  either some yahoo is talking on his cellphone or the projector bulb is at its life expectancy and the image is darker than night. With my home theater 10 foot diagonal 16x9 screen with an analog 3 tube projector with 7 horn loudspeakers sitting 10 feet away, I can be immersed in either the movie or concert experience as well or popssibly better than being at the original venue. You can't do that with a 30 inch television and 2 speakers.

7. I have been to Romy's and find his audio system to produce the best two channel sound I've ever heard. I just wish he would now go forward and use his expertise to produce a video-surround audio experience to equal it rather than settling for a 1990's setup. 

I do admit that the 5 channels in the way how they were made in 90s, when I did multichannel for video was very bad, there is no argument in here. In fact the multichannel were artificially encoded and extracted from 2 channels. Do you think it is being done different now? Do you think that recording 5 channels on BlueRay nowadays they record with 5 microphones on 5 independent channels? I do not think so. I very much think that they extract 5 channels from the same 2 channels. Why would they go for expense and complexity to do multichannel recording if 1) no one would distinct it from artificially made multichannel and then up-converted to 24/96? Nowaday they release the WWII recording in SACD and claim that they “sound better”. What else might be said?

I am not against to try multichannel but I do not feel a NEED for multichannel Sound and for the whole notion of surround channels. Sure it might be implemented and it might add some special illusions but I honestly do not feel that this illusion is truly essential or even beneficial. Perhaps I did not hear the properly made multichannel. In your room when you played multichannel sound was good but I did not find it good because of it multichannel, in fact I did not exactly understood when it was multichannel. Perhaps I need to visit you and you need to play to me the very same fragment in multichannel and in 2ch PCM. I think this would be an interesting experiment.

Again, we do not know what they do with 3 left over channels if they did record in multichannel. It is highly possible that they mix 2ch with the left over from another channels in order intentionally compromise 2ch and sell more multichannel. They do the same with CD layer of SACD format, so I have very little of any expectation to the industry crooks. I know that they would fuck up whatever they are able to fuck up….
