roy, a naim nait isnt a bad one if its your first 'proper' amp. It should perform faultlessly for you, and being Naim you can sell it for what you bought it for in five years time.

theres a nait 3 at the emporium (www.emporiumhifi.co.uk) for £250. You might get a cheaper one from e-bay, I dont know.

to be honest, I think its at this kind of price point that Naim stuff really shines.

If you want to spend less than £250, I think Rotel is a good shout too. You can get a 'passable' second hand Rotel amp for less than £30 on the used market. I have one right next to me attached to the PC as we speak! Dont dismiss it on price, I'd put it up against anybodies new amp at £200.
