Streamer Advice

Another vote for the WIIM Ultra. It has many features & connections you’ll ever need. I kept it simple & matched it up with the FOSI ZD3 DAC & added the openness & separation that anyone would need. The built in EQ & room correction are nice features. 

I found the Lumin U1 mini  a set up over both the bluesound node and eversolo 6 that I bought owned.  I believe its in your budget used.  I like it so much  I upgraded to the Lumin U2.

I don’t think any current streaming service offers MQA… Tidal dropped it last year 

Music Direct had “demo/open box” Aurender N100 for $1600 with full warranty- at least as of a couple of months ago. Mine looked new and totally outclassed my Node with LPS into a Pontus

Since you don’t have a description of your system on your profile page, had to stalk some of your discussions. Seems like most of your system is fairly nice. 👍 Do as @soix suggested. This will give your Meridian a much deserved rest. Plus this will kill two birds with one stone. Remember as important as the loudspeaker is in the system. There are many who will argue that it’s the source. Seriously look at INNUOS, LUMIN, or AURENDER machines. These are the brands that get the most 👍.
P. S. If you list your system on your profile, you will get a much better responses than I from much much smarter people than I trust me on this one. Hey enjoy the day. It’s raining here in Washington.
