What is the best tube integrated amp?

I love tube amp since I started to get involved this hobby. I have also listened to many tube stereo amp, monoblocks and integrated (not too many?)amps. But right now I have tried to look for a tube SET or PP integrated amp for my office I still not find for my taste especially vocals, classicals and instrumentals. Therefore, I need some help from someone who has had more experience than me about the tube integrated amp for a small office. I also want to look a pair of monitors which are matched with. Thanks to everyone who anticipate in this thread.
