Guidance on Speaker Wire

I’m looking for guidance on some speaker wires and have tentatively settled in on Transparent High Performance 10-2 with the Transparent 10-2 Brick Network.  My biggest issue is I have long runs from my amps to the speakers at approximately 60 feet each.  Due to size of my system it is not possible to move my equipment any closer to the speakers.  
My amps are 1.2 KWh McIntosh Mono’s and my Speakers are Martin Logan Electrosatic ESL 15A’s. I also have 2 Martin Logan Force 12” subwoofers that are used for home theater.

@woots’For 60’ or 20m runs with your amp/speaker setup you could use 12 or 14 gauge speaker cable rated at 99% OFC. This will keep your budget affordable and sound clean. You do not need the hyper expensive so so cable. Make sure the connectors are as good as you can as afford and cleanly connected. All good 😊. 🇦🇺
Thanks to everyone who has assisted so far!  Unfortunately, I am not able to locate my amps any closer to the speakers which I know would be ideal.  Keep the ideas coming.  

The reason the run is 60 feet long is based on getting the wire from my mechanical room to my listening area.  I have to go through the ceiling in my basement then drop down the wall behind my speakers.  I have had two installers come by and this is the only way we have found it to be able to work.
Use any good ofc copper of 14 awg from monoprice or like company. Run one wire for each terminal. Twist the ends together and terminate with preferred connector. Use shrink wrap to color code. If effect you’re getting two 14 gauge wires on each terminal you’ll need to run 4 wires. It’s easier to manipulate and you can get a 300ft spool from monoprice for about $100. If preferred you can get 12 awg for a few more dollars. 
Richard Vandersteen has always said for best sound you need to go with the shortest speaker cables possible. If you have no choice for long runs they need to be your inner connects for the components not the speaker wire. You need to rethink your set up.
sgreg1 is exactly correct.  If you can run two 60' lengths of speaker cable than you can obviously run a pair of 60' length signal connecting cables.  That is still a long run so it would have an impact on the cost-per-foot of signal cable, unless you have an unlimited budget.  But still, you can get a reasonably good quality pair of 60' signal connecting cables for a few hundred dollars.  Is there any reason that you can't locate your amp where the speakers reside and leave the rest of your system in the mechanical room?  It would be so much better to connect a fairly short pair of high quality speaker cables.  Given your circumstance, you would then have the best solution for sound quality.
