What is your favorite budget streamer?

Wiim or ifi

Used Bluesound Node 130 (I currently own), or the new Bluesound Nano.....though I don't have any experience with it.

I really do not think anything ~$1000 can beat Holo Audio Red. If one is willing to spend extra money on high performance cables and fuse, Red can perform way above based on my experience. 

I was setting up a budget system in one of my bedrooms to utilize a pair of Polk Audio Monitor 10's that I bought new in 1988 and a Reisong A10 EL34 Integrated Amp I bought in 2020.  I was only doing streaming, and after some research I went with the Audioengine B1 Streamer for $189.00 and a Schiit Audio Modi+ DAC for $129.00.  I have been absolutely thrilled with the ease of use and performance of both items.  These together are under your budget, and since you don't need a DAC the Audioengine B1 would be well under your budget.  Hope this was helpful. 

Wiim has the best software, easiest to setup and use, with the most features. No bugs,  no issues.
