Why do I "need" Audirvana, Roon or the like versus just Tidal App?

Hi, I stream Tidal MQA and their hifi via my Macbook Pro. I use the Tidal app on the MBpro which unpacks MQA, contains my playlists etc. In the future, I may also stream ripped cds on very rare occasion from a connected hard drive, as well as any hi res audio files I may purchase. However, 99.9% is an is likely to continue to be Tidal streaming. Maybe, just maybe adding Quboz or Amazon in the future...

I feed this from my MAC via USB out to my integrated amp and DAC (Peachtree Nova 300). I have no plans to have a separate server etc in the short term, …but may do so in the future.

I cannot understand what, if anything, Audirvana (or Roon and the like) would bring to.the table in my scenario. Perhaps better MQA unpacking? Slicker interface? Better sound quality?

I would greatly appreciate you all's thoughts on this! Thank you very much.

Are you people aware that the most well known music artists make only a few hundred dollars a year on their music being streamed by Tidal, Spotify and others?  Thats right, only a few hundred.  Knowing this, I will never stream.   Because of this, many good musicians are calling it quits.  I always purchase the physical media so as to give the artist a little extra.

So all of you who are streaming music for a small pittance are actually harming the musicians you love so much.  Think about it.
Roon has a great music discovery algorithm, streams and DSP based equalization, multi device synchronization, etc.

It lets you treat your ripped music and Tidal together as one giant virtual library.

I use Tidal on my phone, and Roon when I'm home.
I can not speak to the Apple products but I stream Qobuz, via Audirvana from a dedicated lenovo laptop. I tested and trialed Tidal, The tidal and Qobuz apps & Roon.  The SQ was noticeably better with the Audirvana & Qobuz pairing.  The software assumes control of the digital sound path, bypasses the laptops resident mixers, becomes the only thing using the Wasapi driver and ensures end to end bit perfect processing before sending to my DAC.  It is a little different with Mac OS. While I am not a huge fan of the interface limitations, I care about the quality more and for that reason, for me, Audirvana is necessary.  The fact that all future updates are paid for with the initial price (Was $75) makes it a great value.
I had Tidal HiFi on a laptop, and it was great for finding new music. The SQ was not as good as CD and far below good vinyl. Was this because I wasn't using a separate DAC?
Yes.  Test again with a trial of Audirvana (Free) & a quality stand alone DAC.  Night and Day.  
My point exactly.  When records and CD’s (physical media) were in vogue, the artists made enough to survive and their live events made them rich over time.  With all concerts cancelled this year and into next year, many artists can’t survive on what the streaming services pay out.  
You don’t. Unless you have a driver.
Stand alone streamer sounds better than audiovarna on a computer. Use the computer to discover music.
Refraining from streaming does nothing for musicians. Hit the tip jar - good karma.
The record companies screwed them back in the day.  Nothing has changed.
Thanks fuzztone.  What do you mean by "driver?"
As a dieta gard roon user 

Roon can offer upconversion of tidals 16 44  to highres pcm or dsd and many dacs sound better this way
“Why do I "need" Audirvana, Roon or the like versus just Tidal App?”

You don’t....IMO, Roon is overrated. If you’re going to keep the MACBook, Tidal or Qobuz apps are more than adequate to perform all the necessary basic functions. And more importantly they don’t mess with incoming bit-stream like Roon or Audirvana. Roon or Audirvana were developed to overcome the inherent flaws of streaming audio from all purpose computers, like your MACBook.

If you want better streaming experience, look into dedicated ‘audio’ streamers whenever you’re ready.
I don’t understand why so many people dislike Roon, if one loves music, Roon is fantastic to discover musicians, you will notice I say musicians and not music, music we can discover other ways easily, but hearing a tune in Roon and maybe liking the drummer, one can just click on the drummers name and find all the other music he has been involved with, I think that is a great feature.
Also the Roon interface is for me great, the product is not perfect, but for me it is very close and is being improved all the time.
I like it.
Gryphon +1......I think some who dislike Roon resent having to pay for the service although it costs next to nothing
Hi Bogbeat,
There are two good reasons why you will want to consider streaming Tidal via Audirvana:
a) Tidal as of now does not provide a mobile app to allow remote control of your MPro-installed instance of Tidal.  Audirvana does, and its interface for Tidal is different but very useable. 
b) Unless your DAC is unpacking MQA downstream, you are reliant upon a software unpack on your MPro.  Audirvana not only unpacks MQA MUCH better, but also plays your resident albums exceptionally well. I am running from a PC, but the difference here is mind-bending.  All for a free trial, and then purchase price is less than $100.
I cannot speak to Roon, etc., but chose this route from the intercomparison reviews out there.

For the record, I'm running Laptop PC -> Audirvana-> Tidal -> Ayre QB-9 Twenty ->Ayre AX-5 -> Paradigm Persona 3F's.
Good luck.

* Forgot to add, I use Audirvana mobile app on iPad tablet to control everything remotely.  - Sandstone
Thanks everyone.  Hi Sandstone!  FYI, I am currently evaluating Audirvana with their trial.  I haven't gotten around to trying the mobile app yet, but sounds like you have it rocking!

Re b): no, the DAC is not unpacking downstream, so to your point, it needs to happen in the Macbook Pro.  I was wondering what did this better, the Tidal app or Audirvana.  Thanks for sorting that out for me.
