Tube vs Tran

As my kids are now in high school and beyond, I am starting to get back into 2 channel music.
I am looking at integrated amps with a budget of about $3000.00.
My question: if we always hear how great tubes sound as far as warmth, sound stage, etc, etc. Why buy trans equipment? If one uses speakers that are good match with tube, why not use?
There could be an obvious answer, and if so pls forgive me. But, I really am interested in what you all think out there.
Thanks
