My old faithful amp Revox lamps and transistors eventually let me go after 35 years of loyal service. Maybe he found a real repairer electronics as there are over a lot ... Meanwhile I chose the HK 3490 because I could not put nearly 1,000 euros for an equivalent amp Revox. I am very satisfied with this HK. Easy installation, good sound surprising my ancient bafles Elipson inherited an editing studio at ORTF. I later adjoindrai them another pair of speakers to gain low or out in 5 points with a serious caison. My chain serves both to listen to CDs and vinyls and with my home theater projector. For tuner, I need to find an antenna system: géographyque my situation does not settle for the small supplied antenna. Maybe he exite a system that would allow me to use the cable reaching to the roof TV antenna I am using more. But overall, nothing else to say "bravo!" this amp whose price is reasonable for a more than respectable musical.
