Hi Rhapsody,
i now do 99% of my listening via Tidal. I don't have an MQA DAC. My DACs do not include built-in native Tidal. I am using a Mac laptop via USB. In one of my systems I use a Wyred4Sound Recovery. Is there something else I should be using in my system, such as a dedicated streamer, that would improve/optimize the sound or should I leave well enough alone? Most servers emphasize storage fiist and streaming second which is why, not having music files, I haven't felt the need to purchase a dedicate music server like a Lumin. I don't have expensive USB cables and was wondering if they really make a difference? Thanks for sharing your knowledge.
Morning over in ChiTown

You would get 20 different answers to this question and there really is no right or wrong answer. So much personal preference involved. From my experience I feel like the Aurenders have "a sound". I like what they do. I use my pc on occasion with a cheap usb cable and it sounds fine and there is nothing about my pc that is special and it still sounds fine. BUT, for me the kicker is the Aurender Ipad interface vs. the mac or pc interface. I prefer interacting with the system via the Ipad and I am hooked on the Aurender app.
Roon is a great interface as well, but for streaming Tidal I just like the Ipad and the Aurender app. No desire for anything else, totally personal preference.
Sonically I could not tell you unless I tried both the Aurender and your current mac set up in your system. You might prefer one over the other, not sure, but I think if you played with the Aurender app for a while via the Ipad you might like it.
One of my systems is never going to have an MQA dac and I don't find it a hindrance to great SQ. Through the Aurender I only get 24/48, the first SW unfold but it sounds great because the rest of the system is to my liking.
Going the pc route you get the 24/96, second SW unfold and sonically there will be an improvement over the first SW unfold and playing 24/48. For you that might make a difference. For me even streaming 16/44.1 through the Aurender sounds great and I'm more hooked on the music that I want to listen to and enjoy vs listening to tracks because they sound a little better but they are not what I want to be listening to.
Any specific questions?
