Is there consensus as to which price steps represent the biggest audible changes ? The question is to do with hearing things in a 'whole new way' rather than the incremental/upgrade 'that sounds a bit better' approach. I am happy with my current speakers at £500 ish but have started looking for something for a bigger room. There is plenty in the sub £1k bracket but things seem to get more interesting after £1500, then presumably another jump after that. Given the number of mortgage worthy systems amongst members just wanted to get a view on what the stopping off points are along the way. Not just a question of speakers, turntables seem to get serious at about £700, is there a benchmark for each component in it's price bracket ?
