I am about to purchase a new Panasonic 42" plasma with an AV Amplifier/Speakers (not sure which yet). My question concerns the need for a tuner. I currently have a SKY receiver which I am about to upgrade to SKY+ which I thought I could use to receive the digital TV channels, thus not needing the Plasma Tuner. All the dealers I visit say that I need the tuner to enhance the picture quality for the Plasma screen. Some have said that I could avoid the need for the tuner if I buy a high spec amplifier that will improve the picture to the Plasma. I am now totally confused - any advice ?
