As a newbi, I need some help. I have a Toshiba 32ZP38 with Pioneer 575A (component) and Sky + via QED scart. I am really pleased with my picture - but want to do something about the sound. Read the What Hi Fi awards magazine which features the Yamaha AV57 - a speaker / receiver package for around £200. Would this signifcantly improve the sound to replace the Toshiba's external speakers? Or should I save up some more and get the Denon DHT550 (about £500)?. Or save up even more and get separates like the Denon 1920 plus Denon AVR 1906 and KEF KHT1005 (about £1000)?. My front room is about 10 x 18 feet - so I think the Yamaha is not just the cheapest but best value for money as the others I think would be too much - help. Cheers.
