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.

Plenty of talk here about Canare cables. Used mainly in studios, live performances and catching on for home use for great cables for the price. Can be purchased on Amazon or mainly places online. I find them a tad on the more warner side but they they don’t give up on the upper end. BH Photo is another place to find them.
Audio Envy cables are very reasonably priced, slightly warm sounding with good bass.Good build quality also.I haven’t tried their speaker cables,but the ics and power cables are very good. There’s a long thread here in the cable forum with lots of user comments.https://forum.audiogon.com/discussions/audio-envy-dang
