I'm with Fatparrot, in believing in a doubling of cost to get a definite audible improvement. That rapidly becomes literally ruinous. So in general, I believe if you are not doubling, you are pretty much moving sideways.
BUT, that does'nt mean that value for money is'nt very variable. There are some real bargains to be had out there, often from small companies, without massive marketing budgets, retailers distributors. I am sure the way to go for me, is direct selling from the manufacturer. Many cable manufacturers go that way and some selling boxes, speakers too. That's were I look for value, especially if they do sale or return.
