hi, try hiway hifi.com,theyve got a nad c315 amp at £180,and wharefedale diamond 9.0 at £80, i bought my jbl es90 speakers from them last year,and they delivered in 24hours!
also try superfi.co.uk,they sometimes sell opened box products,i got a nad c445 dab tuner for £249,saving £100!!and its absolutely mint condition!also ive bought a nad c660 cd recorder off ebay from a private seller,which is mint condition,so second hand is worth a look.richer sounds do have some bargains,so id definately look there also,good luck!
