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

Lots of things to look for/at. Among the things that you may actually FIND (i.e. the manufacturers actually disclose) are
pre: output voltage, nominal output impedance & highest, input impedance
amp: input sensitivity (voltage for full power), input impedance, bandwidth.

Unfortunately, you'd still have to listen to any pre-power combo to come to definitive conclusions! Cheers
