In your experience what is the time reqd to get this one going...
Well it looks as if you need just 2 HDMI cables. I have experience with three brands and I liked all of them.
1. 'Oppo' HDMI cable that came with the DVD Player. This is obviously out for you.
2. DAC HDMI cables from Designer Audio. These are very good.
3. Cables from a German company called Eagle. These come at Rs.2100 for a 1 meter length and also very good.
Time to get a HT system going? Believe me it is a perpetual tweak for me. But I do that because I like tweaking. Jokes aside, you should get the system up and running within 3 to 4 days. I have found the video setting and sub woofer setting to be the most challenging. In video setting everything is easy excepting Hue and Tint. If you get those right, it is easy afterwards.
When working on the subwoofer, see if you can play a note one the sub and on another speaker (say Front Right) alternatively to compare. If you reach a setting where the two sounds merge and the sub does not overwhelm the other speaker, you have set the sub properly. It is important the low frequency sound from the other speaker should not stop. In other words, the speaker should start the note, go low, and the sub should take over below a certain frequency. This is difficult to 'hear' but repeated attempts will get your ears twitching, and you can set the sub properly.
There are lots of guides available in RealTraps - Home. In addition they have a special tone from subs that can be downloaded from RealTraps - Test Tone CD. Cut that into a CD, and you are all set to get your sub working well.
Cheers
