Streamer Advice

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.

The reason I want to upgrade is the Sonos does not support MQA.

It seems like you have read some articles from a few years ago. Ignore all that MQA garbage. That suggestion posted by soix above is a good one, and it is from a dealer- if you are truly looking for sound quality improvements it would be really hard to do better than that for the money, considering how much does 500 GB of music cost? It will be gone soon guaranteed.

The reason I wanted to get MQA, is when I stream to my Sonos it gives me the options of using Flac or High using Tidal Connect. When just listening to streaming only from my Android phone Galaxy S22, it will let me select either Master, Flac, or High but when I stream to the Sonos I don't get the option for Master so I just thought the Sonos doesn't support it and I should upgrade my streamer.

This is why I wanted to upgrade.

MQA is not a format being adopted by the music industry, high resolution files are whats being used today. MQA is dead. Plus the limitations of the SONOS prevent it from streaming at the levels you want , upgrade your music streamer to a streamer that can handle the super high rez files. 

I updated my description in my profile so you know what's in my system.
