New Member And few questions on First Tube Amp.

Little about me.I am 67 and more into cars /cycles but enjoy music during winter months.
I have Tinnitus very bad and so I can not play music much over 70 db with high pitch horns ect.
But I have Marantz SR 8002 and had until last week Mirage M-5's. 28 yrs and did not realize how deteriorated
they become until someone sold a pair of Definitive Techogoly BP 8080ST and I could not beleive what I was missing
on sound.. All along thought it was my hearing..So now that I can hear music separation along with my ringing 
it is a joy to hear more than I thought I would ever hear again.
So with that I want to just see if a tube amp will allow me to hear music flow from the speakers as others describe.

So not knowing anything I have a dealer not to far selling Prima Luna tubes and my question is I see tube amp and pre tube amp.. To try a tube amp can you run from just one of these components ??
Does Prima Luna have a all in one unit if I need a amp and pre amp ???

I do not mind spending few thousand, but not sure how long my hearing will last  and so just want to 
purchase low end just to see if I can hear a difference of tube vs solid state...thank you Joe
