How do I choose a phono preamp?

I landed on on a VK-P5 w/Superpak option which adds a power supply and capacitor upgrade.  Based on @thecarpathian's experience with his P5, I live with it until I'm certain that I want to continue to enjoy vinyl.  It's supposed to be delivered on Tuesday, but I can't listen until my preamp comes out of the repair shop.  

What I need to understand the realationship between the phono stage and the cartridge.  Seems complex with talk about resistive and capacitance loading. Where does one go to learn about those topics?

@patrickalston ,

Have you received the BAT yet?

What are your thoughts?

@thecarpathian 

<sigh> Yes, I've received it; however, my system is down pending a cap upgrade to one of my amps.  Also, I'm in the middle of a preamp change.  My old BAT VK-52SE was having problems with its right channel.  So, I'm replacing it with a BAT Rex which, because it's a two chassis  design,  requires me to find a  place for it on my haphazard equipment stand (literally a bench and a 40-inch high table for the turntable).  I'm out of space.  

Sadly, no tunes for me until those issues get sorted. . .

I spend evenings transferring my old albums into new protective sleeves from Vinyl  Storage Solutions (a satisfying task) as I wait for Fedex to deliver new records only to have them stack up unopened in a corner next to my what remains of system.

So, to answer your question, I don't yet have a thought to share on the VK-P5.

Ah, unfortunately these things happen. My integrated is down .

If that's the worst life throws at us, we are blessed.

Agreed.  I count my blessings everyday.  Rest assured, though, I will share my thoughts when I get it back together.
