Hi Rob
I'm not in a position to afford anything beyond what you might call "decent budget" gear at the moment. For clarity, that's a 2021 Rotel A11 Tribute, 2022 Rotel CD14 and Rega P2 with mid-2000s B&W DM 602 s3 speakers on Atacama 60 stands. Perfectly nice stuff, but no component over £500. I was replacing some 1990s gear - as I couldn't afford the more expensive stuff e.g. an A14 amp or P3 turntable, much less something like a separate power amp, I decided to try improving the system with things like home-made power leads, better speaker cable and home-made interconnects and was surprised at the improvement in sound for very little outlay. By that I mean power leads worked out at £15/metre, interconnects £25-£35/metre and AudioQuest Rocket 11 speaker cable at £12/metre. I got the speaker stands 2nd hand for £30 through Gumtree. Definite improvements for a cost that your wife wouldn't baulk at, plus the satisfaction of using something you've made yourself 🙂
