Really like this dac/amp combo and I didn’t know they made an upgraded version. Something to look into if you want a solid portable dac/amp
“Building on the success of the highly regarded Xduoo XD-05—a DAC/amp that changed the game with its versatile desktop-to-pocket portability—the Xduoo XD-05 Plus keeps old favorites while adding a host of new features. New on the XD-05 Plus are an AK4493EQ DAC and XMOS XU208 USB chipset to improve sound quality, as well as onboard USB-C ports to update connectivity. Another new feature is the lithium 5000mAH battery, which is capable of 13 hours of playback via USB, 21 hours via SPDIF, and 40 via aux in. Also upgraded is the power output: The XD-05 plus boasts an impressive 1000 mW at 32 ohms—ideal for even the most demanding headphones. Like its predecessor, the XD-05 Plus allows you to change out op amps without soldering to suit your listening preferences.”
Seems like a nice set of upgrades.

It is a little more then before at around the $250 range, but I would think it could easily compete (and beat) some portable dac/amps in that price range
