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

I forgot to mention. For me the single most important spec is tracking ability. The lowest I will go is 80 um. After that it is by manufacturer, the ones I know build a quality product and back up their work such as Ortofon, Clearaudio, Lyra, and Grado. I tend to avoid Cottage industry makers especially if they are foreign. Some importers may not be trustworthy and they are responsible for backing up warranties. Super low compliance cartridges do not make sense to me. They require heavier  tonearms with much higher moments of inertia. They do not follow record irregularities well leading to increased distortion and record wear. Shorter lighter arms with higher compliance cartridges is the way to go. I do not think tracking angle errors are as important sonically.

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. 

This is all irrelevant when you're using MM or MI cartridge.
Start with MM or MI and you are fine with every MM phono stage!

Don't buy an MC if you don't understand anything about gain, impedance, compliance etc
