Now that I haven away my xm2 as a Christmas present I am totally committed to the XM4.
Some time ago I read that a weekend discretionary purchase topped out at $500. That means tha a young person could purchase the hip dac combo for less than that id the find the SONY at a discount. That means they can can access quality sound while on twitter, facebook, instagrqam, Tik Tok (all trademarks),etc. No need to build a music library. They can access streaming services such as Tidal, Pandora, Spotify, etc. Many for free if you don't mind the increasingly annoying commercials. Most offer a reasonably priced commercial free version. Not bad.
