So where should the tubes be?

I was on another forum and a guy that identified himself as honcho at Bob Carver company stated that the place to start with tubes is the amplifier.  This was different than the opinions of many here that the preamp is the place to start with tubes.  

I don't like fiddly or expensive, so I decided to start with pre — awaiting receipt of a Schiit Freya now.  I will keep the SS preamp for variety and when the Freya is down temporary while I await tube replacement.  

Tubes should be where you amplify an analogue signal. 

" but extend it into amps with speakers that mate."

Say what?

"I prefer them in the pre and phono stage at minimum but extend it into amps with speakers that mate."......

I am simply saying when the choice of speakers mate with a tube amps ability to drive them I will extend tube use and introduce a tube amp into the mix.
If speakers too demanding, SS is used for the amp. Sorry, thought mating speakers and amp was pretty basic needed thinking...

@three_easy_payments well played sir!
