Higher End DACs

@rms456 
Not real sure what you're saying but DACs aren't measured in isolation chambers as if it was connected to nothing but a power supply.

Just like OP, I was looking for a streamer/DAC. I have been following this tread and learn a lot on the ongoing discussions. Based on @audiotroy recommendation to OP on the T + A SDV3100 HV, I bought the SD3100 HV and expected delivery next week. I am brand new in streaming and need help on the best way to setup the system.
I have a 80 feet CAT7 cable from the router to my music room. I want to use Roon and Tidal. I have a 6 years old Macbook Pro and a iPad Pro. 

@khiak  First, congratulations on your T+A SDV 3100 HV.

Since you are "new [to] streaming" ... as a starting point I recommend going with Tidal first. That is Tidal direct, versus going through Roon.

The SDV can accept Tidal Direct wireless or via your CAT7 cable from your router. You can control Tidal via your iPadPro (using Tidal's App)  OR directly via the T+A Control App which offers Tidal, qobuz, Deezer, control.

@david_ten many thanks for your recommendations. Shall keep to Tidal. Is the Tidal app more user friendly than the Tidal in the T + A Control App.? By the way I bought the SD as I have a preamp. 

@khiak I expect the Tidal App on your iPad will be vastly superior and I encourage you to use it.

The T+A app will allow for simple control of Tidal.

I have the SDV. Congrats on the SD!!!
