Look into a used Auralic Aries G1. Does wifi, caching, linear power supply. Nice user interface as well. It’s slightly brighter sounding but not to a degree to become offensive. Within the right system and paired with a good dac it will be very good.
Being the older model, I think you should be able to pick it up at a reasonable price. Auralic is highly regarded.
