I had a demo at lakozy. I did not compare it with the other system there, as it was in another league with very large pair of subs etc. There was no comparable htib there to compare either.
I watched Dark Knight blue ray (oppo 93 was the player) for about 30 mins and I did not miss any dialog. It was quite clear. The sub punch was decent, of course it was not throwing me off my seat like the other setup did. The other setup, I was bracing myself whenever a bass heavy scene came up.
At least it merits a demo. Listen and decide. It is great on the convenience and ugly speaker wiring fronts.
Regarding screw type bulb holders, IMHO, existing bulb holders should not be too expensive or too complex to replace. This opinion is NOT based on actually trying to do it, but Ashish can give reference of places in delhi where to buy it. Maybe he can arrange them too. I have seen screw type cfls also being sold in the market, so a holders should not be too difficult to find.
