Welcome!
So what sort of system do you prefer?  Does the room or possible change in musical tastes make a difference?  
My first serious system included solid state pre/power amps and large 3-way loudspeakers with transmission line bass, wonderful but the those transmission lines were too much speaker.  Shifted gears to smaller stuff before moving to a small combined audio and A/V setup.  Then got serious again, built a listening room and commissioned floor standing single driver transmission line loudspeakers.  Tried various tubes, even active monitors (which I liked), but have settled on class D, streaming, and those commissioned loudspeakers as the best sound/lifestyle for me.  Currently am hooked on a commercial free 128 kps web radio station of laid back jazz.
