Can we assume your budget is up to about £200?
Both Pioneer and Yamaha make amps in your price range, or pressing the high end of it.
Pioneer -
Pioneer A109R, 20w/ch, £119 -
PIONEER A109 AMPLIFIER - available from Superfi UK
Pioneer A209R, 35w/ch, £139 -
PIONEER A209R AMPLIFIER - available from Superfi UK
Pioneer A307R, 45w/ch, £179 -
PIONEER A307R AMPLIFIER - available from Superfi UK
Personally, I wouldn't consider the Topaz or the A109R, but the A209R should have sufficient power to get the job done. However, the Cambridge Topaz AM10 with 35w/ch might be worth a look at about £169 -
Cambridge Audio TOPAZ AM10 Black | Stereo Amplifier | Richer Sounds
Yamaha AS300, 60w/ch, £206 -
YAMAHA AS300 AMPLIFIER - available from Superfi UK
Pushing your budget, but a little more power, and this is the latest and greatest version of the Yamaha amps.
Right at £200, would be the Marantz PM5004, 40w/ch -
Marantz PM5004 Black | Stereo Amplifier | Richer Sounds
I would help if you would give a clear statement of your budget. The Cambridge 350A is about £229. If you can go that high, then also consider the -
NAD C316, 40w/ch, £215-
NAD C316BEE AMPLIFIER - available from Superfi UK
Nothing wrong with the Cambridge 350A though, that should be a fine amp for the price.
If you can push up to near £250, then I can suggest some other amps.
That should give you something to think about.
