Don't get sucked into all the luddites front end arguments - one of the many distinct advantages of the Devialet is it's incredible DAC and built in streaming via Ethernet or wifi. With Devialet Air 3,04 (just released) running on your MacBook you can play Tidal with MQA and 16/44 directly or better still through ROON and control it all remotely via an iPhone or iPad. Going over wifi eliminates any galvanic noise from connecting wires and sounds better than Ethernet, USB or AES too. Better still you can have your MacBook in another room and on an entirely separate leg of power. Getting a dedicated 20amp supply to your 440 will help a lot. Feel free to reach out if you want any specific Devialet setup help as it can get a bit technical! Equally, you can use you MacBook to rip/copy your CD's to an external hard drive and have access to those through ROON.
A good power cable works wonder with Devialet. Try Triode Wire Labs, Lessloss, Wireworld or Analysis Plus. All reasonable $ and great matches. Same companies for speaker cables.
if you do upgrade your speakers after trying all that you'll likely find the cables just fine but may want to revisit your cable options. Buying used cables is a good option.
Good luck.
