Tube Integrated Amp to Drive Floorstanding Speakers?


forgive me, but i'm a relative newbie to audiophile concepts.  i am looking to build a 2 channel system for music that i can grow with.  currently i have a VPI Prime, Soundsmith MKIII cart.   I'm using a vintage kenwood KA-9100 driving Elac Uni F bookshelf speakers for my office.   

in the future, i plan on a listening room of 15x20, give or take.    I am intrigued by integrated tube amps - looking at all sorts, including PrimaLuna, VPI 299d, etc.   but these amps have lower WPC outputs.   I'd like to grow into a floorstanding set, something like the Monitor Gold, KEF R-series or PBS Imagine T3 range.    My tastes range from Classical to Classic Rock.   i do not blast music by any means.    Is an integrated tube amp (35-40 wpc) sufficient and will it leave room to grow?   ideally i'd like a home threater bypass should i decide to add TV that into the mix

thank you all- i appreciate the input.  to be clear, i'm at the research stage, by no means ready to pull the trigger on anything.   I just wanted some input on the possibility of using a tube amp, and you've answered it.    where i live (Long Island), it is geographically difficult for me to demo speakers or amps, so i thought it might be wise to plan to acquire amp and speakers simultaneously as i'm sure i'll be working with an online dealer.   thanks 
Ha- Soix - where are these dealers on LI?  you got a 2 year old running around like i do?  manhattan is not the hop, skip n a jump that it used to be.  
sounderm- you had me a 'poo-poo' !!. thank you, that was exactly the analysis i was looking for.  I have read great things about the KT120s.  thanks again, enjoy your system.
