New to Vinyl. Need help on how to match components, cartridge, etc...

Thank you, all.  Much food for thought and your comments are very helpful.  

@millercarbon  I have Bryston 7B3 amps which have a very low input impedance (7.5k unbalanced / 5k balanced) so I stuck with a Bryston Premp which has an output impedance of 72 ohms.  This is my concern. 

@chakster  I would like to stick with a MC, hence my seeking of guidance as I am definitely still learning.  Attempting to do my due diligence prior to making my purchase decisions on both a cartridge and a phono preamp.  

I should have referenced the B26 Preamps input impedance rather than the output.  The input impedance balanced is only 10k ohms per leg. This what is giving me concern in regard to matching up an appropriate  phono preamp.
