Separates to tube integrated


I have been on an audio hiatus for a few years, like 10+. I am seriously considering selling my separate amp and pre-amp for a tube integrated. I want to keep it simple and classic. I currently have a Classe CA-151 amp and Classe SSP-25 preamp (used to have a surround system which is why I have the SSP25). I don't do video anymore and no vinyl so a phono stage is not part of the decision. In my past systems I have owned some tubed Pre-amps from Conrad Johnson, Audible Illusions. I have always enjoyed the sound of tubes but never owned a tube amp. These days I want to keep it simple and straight forward, pure 2 channel audio, mostly CD's and a streamer of some sort in the near future. I am currently running the B&W CDM9NT speakers. Was looking at a tube integrated like either the Primaluna EVO 300 or Rogue Cronus Magnum. Again, no phono stage needed just an audio source or 2. Based on a lot of the customer reviews I have read I am leaning on the EVO 300. Do I stand to lose any by going to an integrated? I am guessing from what I have read I will actually be gaining. I am trying to find one in my area to listen to but with this whole virus thing its tough and nobody has one anywhere in my region. Thoughts?

@avanti1960 you do have a point. I am happy with the Classe amp, drives the B&W's nicely. The preamp is something I bought when I had a surround system, so maybe just a nice tubed pre will give me the best of both worlds. The RP5 is a little out of my price range, but I will explore the tube preamp world. See, that is why I come here for suggestions. 
If the B&Ws are not long-term keepers I’d be hesitant to choose an amp now, especially if you like tubes.  Other speakers could open up a lot of other amp options for you.  Just my $0.02 FWIW.
