Krell KAV 300i, How reliable is this amplifier?

I bought one brand new and used it for three years before selling to go back to separates with only one problem -- the shielding on the RCA plug ins on the back panel came off on two of the connectors -- Krell fixed it under warranty.

I bought one in 1997, plugged it in, turned it on, shutting it off only for vacations. Used it for just over 5 years and sold it last year. Bought another 300i used later in the year and ran it for 6 months. Never had a problem. Only a change in loudspeakers rusulting in an incompatibility has caused me to move on.

I owned mine for about three years. Bought it new and never had any problem. Because of its fine performance I stayed with Krell when I moved up the food chain to an FPB.
