"All-in-one box system" that is High End

I am looking for a system to turn on every day when I come home from work, but does not require long warm-up. My main system is preamp with separate power supply, my amps are tube mono blocks. When I play I sit in one position,don't move and concentrate. This should be the walk-around system. I am looking for something that sounds 90 % of my high-end system. I have seen a lot of postive reviews on Linn Classik. Can I live with the basic (inexpensive system) or should I forget about all in one package?
