I purchased this in 2021, Its in great condition and has the original packaging. Note this is the Pro version with MQA support. It has a 1/4 port and 4.4mm balanced headphone jack for high-end audiophile headphones, also supports Airplay and Roon via Wifi or Ethernet. Its been on my desk powered off when not in use. I moved and use primarily use speakers now so its a bit overkill for that. Includes a really nice remote to change sources and adjust volume.
