5 minutes versus 15 minutes needed per room, not so different here.
I've learned to start at the top and work my way down the stairs.
Small shows you can visit everything and have enough time, bigger shows you have to decide whether to give 5 minutes per room or concentrate on a pre-selected number of rooms. Pros and cons each way. 5 minutes isn't enough for a decent listen to stuff you're interested in, but concentrating on a few rooms means you missed stuff you didn't know would be there.
I know, even with a 15 minutes listening, how can you give an credible opinion.
Well, I did say in one of my first post, that I was not a good audio show reporter.
Next year, if I am still on planet Vietnam,
I will do more critical listening and less picture taking.
I might be wrong, but for me, if with the first few minutes you are not impressed,
then why continue ?
The two or three rooms that made me stay a little longer were
two home cinema set up and one fairly modest system.
In one of those rooms was a Samsung home cinema set up.
Looking at the components it was nothing to impress you.
A sound bar, aiming at the ceiling, two satellite speakers, probably two ways with 4 or 6'' woofer
and a separate subwoofer, maybe an 8'' and that's it.
But the sound was holographic, three D, I was really impressed,
which is rare on audio shows I go to.
The bass was different from the usual earth quake type,
more natural and I would say, less fatiguing.
The movie was The Transformer so a lot of crash, rumble, etc...
But it's the audio three D effect that caught me attention
and made me stay 15 minutes and during the whole demo session.
They had demo every 15 minutes to fill the room with people
and believe me the room was filled wall to wall.
