Streamers - Auralic, Aurender, Lumin, others...

Why do you need a streamer since you run roon on a mac? 
if you just need an end point, you don't need a streamer.

Couple of suggestions:

1) keep running roon and buy a great dac that has an ethernet input. Your dac will be a roon endpoint. Did this for years because usb sucks as a dac input.

2) get a dac that uses i2s (which is even better than the network input) and then get a streamer that its job is to convert the network input and exits to i2s for your dac. This is what i do for the last year.

Besides all this, if you are running roon on a mac running osx, switch the operating system on the mac to linux and roon will sound better. If you have a newer M series mac mini, pick up a used 2013-2019 trash can mac pro to run linux and run roon on this. This is exactly what i did a year ago. I still have a m2 mac mini as a server with 10TB of ssd/m.2 nvme storage, i have a permanent link from the trash can linux server to my m2 mac to the storage for all my tbs of ripped music. I have a 128g ssd on the trash can mac for the roon backups. Simple, i backup the roon storage from the m2 backup that runs daily. Everything runs very fast, roon arc runs fine.

The other option is to run qobuz connect which actually sounds better than roon with linux. 

I've used an Aurender N20 with a 10 Mhz clock for several years now and it's been flawless. I've just paired it with a ACS 100 which takes control of the library functions, leaving the N20 to create music.

Best I've heard under $20k.

@gabriel123 with my DAC it is at least as good.  The Esoteric K-01 XD component is rather forgiving of the input.

To quote "In summary, the Esoteric K-01 is a high-end component whose engineering is dedicated to maintaining the purity of the audio signal by actively combatting various forms of external and internal interference and variations, thus making the final output highly consistent and faithful to the original source, regardless of the input's potential shortcomings. "

The T8 reviews have been positive (google Eversolo t8 reviews).  There have been reports of software glitches with other Eversolo products but I have 3 units, the T8 in my big rig, a DMP A8 in my "Kitchen System" - A8, Elekit TU-8600, Harbeth P3ESR and a CD-Play with Dynaudio speakers in my wife's studio.  The T8 initially had a bug so that the USB connection was limited in bandwidth, this was fixed a couple of weeks later by the firmware update.

I am very satisfied with the all the devices.  You do need to plan on 30 minutes to get the settings and options optimized - e.g. paring down the list of services that show up under "Streaming".

I put a 4GB SSD in and am, very slowly, ripping my 2,000+ CDs.  If you do add the SSD make sure you select a formatting option compatible with your computer or it will not be recognized as a shareable device.

It is 1/3 the price of the Aurender N150 and a fraction of the price of their higher units.

I recently moved from BluSound Node2i to a Lumin U2.  I am absolutely blown away by the sound difference, much more than expected.  I'm an electrical engineer that focused on embedded systems so I didn't expect this should have made any difference since I also used an external DAC (like you're doing) and extracting a bit-perfect copy of the data of the signal at the DAC really shouldn't be very difficult for audio data bandwidth.  I tried it really for fun with some hope that maybe it would help a little bit.

I am still star struck with the improvement in the sound and sound soundstage.  I can't really explain it and have kind of lumped it in the "black magic" category.  But whatever the reason for the improvement, I love it.

I'm sorry I can't actually answer your question (comparing the 3 brands) but I can give a solid vote for Lumin - so far anyway.  It's only been a month or so but it's been solid.  I am a bit nervous about the possibility of the company failing, but that's true of any high-end audio company, especially smaller ones.  Their app is OK but not amazing.  I am using Roon on it for now mainly, but sometimes I switch over and use their app.  I actually use Amazon Music (free trial) and Lumin supports it natively (unlike most and disappointingly, Roon).  I will say that the overhang in the back (to hide the connectors a bit) is more annoying than expected.  Mostly it doesn't matter, but unplugging the XLR is a rain pain if you have larger fingers - the lock is very tough to engage while pulling out the cable).  So if you're a frequent cable switcher and use XLR, that is a negative.  

As per prior post, differences are about noise.  But it’s not just the streamer.  Different dacs, even very expensive ones, can be wildly different with respect to their vulnerability to noise from a streamer.  In some cases, a dac may not sound noticeably different when hooked up to a Raspberry Pi or a Mac vs. a high $ streamers.  In other cases, for example some nos dacs, they are highly vulnerable to jitter, and same streamers could make big difference.
