Im going to regret my cable question

Having read so many "do speaker cables matter" threads, reviews, etc., over the years I am going to open up this can of worms again. So here goes.

I would like some opinions on the pairing of my amp, speakers, and a possible upgrade of speaker cables. My kit consists of a Rotel Michi X3, S2 and Monitor Audio Gold 300 G5's.

Would anyone venture a suggestion on what might be a good fit, with a budget of no more than $1200 CND.

I currently have Audioquest Type 4 which are some years old by now. Im looking at AQ Rocket 33 or 44's but I am open to other brands.

Although I understand the "coat hangers work just as well" theory I would prefer only constructive suggestions from those who feel there is a benefit to cable upgrades please.

Cheers.
