Node Nano - best bang for the buck entry level streamer and you can power it from a linear power supply thru the USB-C port. It made a good source with USB into a Holo Cyan 2 as well.
Node Icon does sound better but with $1k+ I would start looking at some higher end used gear.
Eversolo is overhyped and shitty power supplies in some models that seem to be failing a fair bit. Although the T8 model does look to be built to a higher level.
I just got an Aurender A1000 on here for a good price. Will report back after testing.
TMR has some used A100 with warranty for good price but I think it has the older software (no Tidal Connect etc).
Used Lumin D2 are well liked by many for around $1k right now but pretty no frills. Just good sound.
