Help with first cable upgrade.


I have a Musical Fidelity v-150, rotel rp-3000 turntable and an old Sony CD player.  I have 2 sets of speakers B&W CM2's and JM Lab chorus floorstanding speakers I may have to part with due to space.  My power cables and interconnect cables are cheap stock.  My speaker cables are a 20 year old or so set of MIT shotgun cables.  Any recommendations for budget friendly cables that may help the bass or soften the brightness of my system?  Thanks.

I also found the Canare wire cables to be decent affordable quality and a bit warmer sounding than some.  
I never tried Canare, but I do have a pair of 10 gauge Belden from Blue Jeans. In some situations they work absolutely fine, even in comparison to some much more expensive cables. But they have sounded absolutely terrible with some other component combinations I’ve tried and the "better" cables sounded much much better. So I do think it’s a good idea to start with Belden or Canare and see if they meet your expectations. It’s important to have a baseline for comparison so you will know whether it’s worth buying something more expensive. But they are not the end of the cable rainbow. I wish they were.
Thanks everyone.  Will try the least expensive first and see how is goes.  I'll follow up with any noteworthy feedback.
The Audience AU24's are way out of my price range so I'm looking at the rest.  I also found a used pair of Audioquest Rubies for $80 online and might give those a shot.  Thanks again.
AQ Ruby… now that’s an old cable. Probably the first decent cable I started with 20+ years ago. I personally preferred the Kimber PBJ over that cable. I’d take the Canare over both.

For power cables on a budget I’d look at used Kimber Kable. You could also build your own with cable from Home Depot and lower price Wattgate plugs from VH Audio
