Hi everyone. ... I'm new to this forum and hoping I can get your gI'mreat opinions and help in regards to my theatre setup where I'm going too install speaker cable which may not be changed in the future as it will be within the ceiling and walls. ... I'm needing to run approx 15-16m (50-55ft) runs to all three front speakers from rack to speakers. I 'm keeping the lengths the same as in told that's the best setup. Would you all agree? Due to the length in needing I've decided I'm best to spend some dollars on quality cables with banana terminals. Does anyone have any of the four cables I'm looking at? Qed xtube 400 which is 4mm2 wire. Qed Revelation which is 2mm2 wire. Atlas Hyper 2.0 which is 2mm2 wire and finally Chord Odssey which is 3.00m2. All of these cables are not cheap. To get 50m which plugs is going to cost about $1180 to $1750 delivered to perth from the UK. As I'm unable to trial any of the cables ive only been able to go off online reviews and what hifi reviews. Please help. My speakers are Focal Chorus 826v towers and matching Centre speaker. I will have twin sub woofers for bass. Was using only monster xp cable and the sound wasn't great and was fairly harsh but got used to it. Since I've got long runs of cable I want to get it right and since I may not be able to access the cables again. Needs to be right even more so. There are other cables such as the Atlas equator 2.0 or qed silver anniversary xt which are a third of the price but unsure due to the length of cables I need to run. These speakers are not bi wireable so only need the single run for now. But may run s Second pair for future speaker upgrades but of something less pricey. .. please help. ..... Cheers.
