What single Upgrade will make the biggest difference to Sound Quality?

[TommoT]

I've got a fairly old Hi-Fi System, but I believe a good one, but I have some spare cash - up to £1,000 and I would love to know what peoples opinion is, as to what I can spend this money on to get the largest improvement on sound quality?

Amp - Denon AVC-A11SR
Speakers - PMC-FB1
Turntable - Rega Planar 3 (old RB200 arm) with Audio Technica VM540 Cartridge
Arcam CD93
WiiPro - Streamer

Amp - this is a powerhouse of a Tuner with a 'Pure Direct' mode for Stereo, but how does this compare to newer dedicated Stereo Amp's in the £1,000 bracket?
Speakers - Great speakers when I bought them, but are newer speakers THAT much better to warrant swapping?
Turntable - Old RB200 arm is an antique now, is it worth upgrading?
CD - I still have 1,000's of CD's and this is still used loads, but even if I did upgrade, what would I even upgrade too these days?

I'm really curious to hear your opinions.

Thanks you

I would keep the money in the bank or spend it on something else.
You´re right, you have a nice set and £1,000 will not buy you anything better than what you have already.
