MH 750 Help?

I have been using generic speaker cable but just picked up MH 750 bi-wired. Can someone out there help me identify the different era's and types. I read reviews but have trouble telling series apart and what is worth. I hope this was a decent price and seemed to be market norm. I know it's not the tube terminators. Was it still a good move? I imagine it will be a huge upgrade from best buy spools.

The slow, i'm poor, building of my system is as follows....
So far I have acquired LSA 1's, was gifted an old HH Scott 340 (Mmm... telefunken), and a MMF-5. My wallet and ears are hoping for a Rogue Cronus down the line. I like the sound at the price, and tubes appeal to me. Perhaps there will be a Peachtree decco2 as a stepping tone.
