Agree that the NAD C521BEE for 169.99 is a good buy.
That leaves around £250 for an amp. Lots of options there. Can pick up a MF X-80 for that or less if you look around.

The NAD C370 can be picked up second-hand within budget and is a great amp. Rotel are worth looking at too:

- would allow more to spend on the CD player.
