I went along yesterday and this was my first time at such a show, so i don't have a comparison point. Here are my quick ups and downs, but bear in mind that i'm an amatuer in this
Blown Away
SIM2 projector demo. I hadnt really ever seen a good projector before as until yesterday, i always thought of rubbish ones in pubs. Awesome ! the step to show anamorphic and the "grand prix" hddvd was my favourite moment of the show, followed by the final demo showing "hot fuzz".
Highly impressed
The Pioneer kuro screens, especially the main demo - together with the Dolby true HD sound clips.
The cyrus demo, using war of the worlds on stage. Sounded lovely.
Epson Projector demo using Pirates.
The top of the range shure earphones, although not THAT much better than my E4c's.
Quite Liked
The what hifi demo, although i thought it was too long to spend on one film.
The plasma in a fireplace idea.
People playing guitar hero on the giant panny.
Dissapointed
Dolby 5.1 headphones
The denon room. Being a fan i went there, but couldnt actaully see any of the main av range in action, so that was no better than looking in a shop window. And no sign of that blu-ray player yet
Absence of Toshiba and onkyo (unless i missed them).
No real 'freebies' to speak of.
Didn't bump into the AVforums guys and have 60 seconds of fame on the next podcast
Although i can't comment on the comparison with other shows, i found it a reasonable way to spend an afternoon and 15 quid, although i would rather attend a show that's bigger and pay a bit more if needed.
Cheers
