Good entry level cables


Hi allnewbie here and I am totally confused. Just when i see and decide on a cable, another thread pops up recommending a different one... and I don't have time to keep changing different brand cables around to see what matches or sounds best. I probably only have an mid level system? So I need a consensus (not gonna happen haha) of what I need minimum now and for what piece of equipment.I have what follows- My room is 20x16. Ceiling height is 10'. Equipement is in the rear of the room. So I need speaker cables from FOH to the rear. This is new construction so I can place cables in wall or in ceiling. Probably 30' run of speaker cable. I've looked at monoprice, BJC, and others recommended on here that are REALLY expensive. I'm already over budget lol. Solid core, insulated strands?Power cables?Interconnects?In order of importance. What is the minimum I need? Best for the money?
Equipment as follows:
Atlantic Technologies 8200 - 2 fronts with 2 subs, a center, 2 pair surrounds4 Revel in-ceiling C763L for dolby atmos
Lexicon RV9Sony VPL-vw695es
Audioquest Niagra 1200Lexicon DD8-A for in ceiling revels (not purchased yet for $999 new) Anything better in this price range

In wall speaker wire  needs to meet NEC standards, you should check to make sure the cables are rated correct.

Dnm reson IC and speaker cable . They are british so availability in the US is limited but can be found . Sonically they are so good as to warrant admission in systems into the tens of thousands . The problem they have is that they are so inexpensive that audio snubs don't take them seriously 
 
Don't take my word for it...just hear them in your system . You will thank me over and over again . Another would be the least expensive cable from JPS Labs . They are more expensive then the DNM but do sound excellent in a wide variety of systems , be then Solid State or vacuum tubes .

Your contractor can do the runs and you can do the terminations as neded.
Id start with Audio Envy and go from there.  Thats where Im at now but I dont plan on going any  further.  I highly recommend them.
