I have never been to the What Hi-Fi show and doubt I ever would as I have found the Heathrow show deals mainly with the more specialist manufacturers, which is more to my liking.
I just found it a big disappointment, my 4th visit in 5/6 years.
Two visits have been great and two have been poor.
I am surprised at your remark of the accessories. Apart from vinyl there was a tiny amount of CD's. Yes Merlin were there, Townsend with their isolation platforms. But apart from that nothing else. Other years have had whole large rooms crammed with stuff.
Maybe its the 'credit crunch' (how I hate that phrase!)
A guy I spoke from one of the larger dealers there said that the top high end kit was selling ok, but the rest of the 'lower' high end were struggling a bit.
Just a comment and obviously no proof to it.
I think also the fact that there was very little of anything new there.
The last time I went was when HD-DVD & Blu-Ray were there battling it out.
Lots of demos on SIM2 projectors. Again nothing, not actual AV what so ever.
I have to say I was generally a bit shocked by the lack of dealers there.
Oh well maybe a couple of years time it will get back to being a proper hi-fi show...
