what to think about when matching pre and amp


im new to tube amps. i hear one have to think about sertain things when matching a preamp with an amp. is it the sensitivity or.. as an example im thinking about buying a Conrad Johnson ls17mk2.. and i can also get a CJ premier 11a. how do i know they match? these would probably match since theyre the same brand.. or..can i think that way. please help

I use the CJ 17 with a Pass lab Aleph 3, which is supposed to be difficult to match because of input impedence I think, no problems. I agree with gregm, if it works, who cares if it should'nt be a good match.
