My hi-fi system currently comprises Sysstemdek IIX turntable, Cyrus 2 amplifier, KEF Celeste Mk 2 speakers, & a new Pioneer BDP450 blueray video/CD player. The over 25yrs old Cyrus amplifier needs repairing or replacing. My knowledge of modern Hi-Fi is very limited. I want to update the sytem to give me the best budget priced performance I can get, and I want to get into audio & possibly video streaming. For downloading & streaming I have a modern PC with home Wi-Fi and a budget android tablet. I am somewhat bewildered by the amount of modern kit available, and am at a loss to know precisely what kit I need, without considering which manufacturer. Can anyone tell me what pieces of kit I need to buy & what of my present sytem can be retained ? Suggestion for particular high performing budget range items compatable with what I can keep of my present system would be helpful, although I can probably find them from the magazines best buy tables once I know what I am looking for.
