Please help me choose the right and best streamer

[Killergurt]

Hi all,

I have been asking questions about how to best stream music to my system and after reading everyone's comments and learning a lot, I have narrowed it down to a few options, which I would really appreciate some feedback on, especially if you have used those devices.

I currently stream music using Mcintosh MB50 connected to C2600, using the C2600 DAC.

The sound quality is pretty great, I stream mainly Spotify and Tidal. Do not currently have a digital library.
The reason I am looking for an alternative to the MB50 is price. It is a costly unit and I am trying to figure out if I can replace it with a less expensive device that can match or even surpass its performance.

I narrowed it down to the following:

1. MB50 (owned) - $2000 MSRP
2. Auralic Aries - $1599 MSRP
3. Cambridge Audio Azur 851N - $1499 MSRP
4. Auralic Aries Mini - $499 MSRP

Have you had experience with any of those and can comment on sound quality/features? I have no way to get the Auralic or Cambridge and try them out, so I am hoping I could rely on your experience.
Also, which would pair nicely with the C2600 (does it even matter)?

Thank you!
