Use of Denafrips Iris 12th DDC with computer

Using general purpose computers for critical listening in high end audio systems totally defeats the purpose of having a high end system. I can understand for background music or discovering new music for physical media purchases. But if this the purpose why even bother playing through main system or taking half steps for improving sound quality. Go all in, treating as an important source component or keep as pure utilitarian tool.

For the price of the Iris, you can get a new Bluesound Node.  As an all in one unit it is a good streamer with a good DAC and great software. I used one for years and the newer ones are even better.

All the best.

Best improvement to computer sound is to ditch it. 

A cheap streamer's cost is a fraction of a DDC.

A computer offers a lot of possibilities and user friendliness.

You could have a HTPC plugged into your big screen and sit back on your couch with a wireless keyboard+mouse. Can you imagine the posibilites? You can watch music videos, watch artist interviews, google things, get on the forums, read the news, etc...do all kinds of things while you're listening to hifi. 

Streamers are a one trick pony, i.e., a dog faced pony soldier.

Go all in, treating as an important source component or keep as pure utilitarian tool.

@sns Big +1. 

Again thanks to all for the input. I feel I need to clarify a few points. 

 I am not thinking of using the Iris in my primary system. I would use the DDC in my secondary system which is composed of a Rogue Sphinx V3 integrated, Musical Fidelity M3SCD DAC/Transport, Esoteric MG10 speakers. I can output from the DDC via SPDIF coax. I misspoke about running out from USB.  I have considered getting a Node Streamer and should I do so I believe the Iris would serve it. Several posted that it made an improvement with it.  

Prior to making any purchase I must first get past the point made by @sns regarding treating as a main source component or a utilitarian tool.
