If you have a smart phone or laptop, a $5 patch cable will get you started. If you have a home network, $25 will get you a Chromecast Audio. CD quality and better. The DACs in most modern computers or phones are pretty good. There are a slew of external DACs available that will give you a noticeable upgrade for around $100 (Audioquest Dragonfly, Schiit Modi).
Of course, you can spend more and get as complicated as you want. But you will be 90% there with just a $5 patch cable. And if you can swing the monthly cost for TIDAL, you may not need to RIP very many CDs.
