Mahier it all depends on what you were doing to stream to your dac.
If you were using a generic computer with a $5 generic usb of course your digital playback woudn't be very good.
Useing J River or Roon to upconvert a 16bit 44k CD via your computer to upsampled 24bit 384k or DSD makes digital files sound much more like analog files.
The Innuous servers using a good ethernet and usb cable sound amazing into a good dac and will blow away most really expensive CD players at 1/3 the cost.
The advantage of having a library is that you can see and remember what you like and own, when you combine having a good library with Tidal to fill out what you are missing the combination is fantastic.
In addition your stored library can be shared throught your house with Roon integrating separate devices such as Nad Blue Sound products with Naim or other higher end Roon endpoints and you have both great sound quality with the modern convenience of Ipad/Iphone/Android control in many rooms of your home.
Viva the revolution!
