Too terminate or not

Final addition to my Harbeth p3esr and Croft Integrated amplifier combo is the speaker cable. Unfortunately I need a 30 foot long run. I’ve narrowed down my choice of cable to Mogami 3103. 

I can purchase the cable in bulk from Performance Audio at $2.86/ft(need 60 ft total). I suck at terminating cables and I can purchase Vampire HDS spades separately - where can I send for professional termination with gas tight crimp and maybe treating the cable with Cryo while there? Take Five Audio sells 30ft in pair Cryo treated and terminated with Vampire spades for $450.

You are seriously going to spend the time and money to add terminals to wire off a reel. Unreal. Oh well, never again pretend marketing is ineffective. At least do yourself a favor and listen to the bare wire before adding the terminals. Otherwise you go the rest of your life imagining it was all worth doing. 
I only use bare wire or professional connections.
You can always wrap the bare wire around the amp post and tighten the nut.
Parts Connexion:

I have only compared the Mogami as an interconnect vs. the Duelund interconnect. For me the Duelund offered better detail and a more articulate presentation. I think a lot of folks like the Mogami though. When I had my Harbeth SHL5+ the Duelund was the most musical speaker cables I found. I replaced Audioquest Castle Rock with them.

I don't like terminating speaker cables, it simply means you're adding another junction (another point of failure).  As an avionics tech working on jet aircraft while in the service I can tell you that most (not all) of your problems will either occur when a component fails or a connection fails.
And its mostly connections, but then again I don't think your rig will be pulling any significant G forces beyond 1.  Leave them bare.
