Use of Denafrips Iris 12th DDC with computer

I thank all for the input.

My primary system is a modest high end system playing CDs via Jay's transport into Audio Mirror DAC. I have explored the purchase of a streamer (say $4K) for this system however prefer the CD avenue at the moment.  I have visited the many AG threads toward that possibility, not having to introduce another.

Streaming is primarily used in my secondary and tertiary systems via Qobuz. Most times I use streaming for background music.  I would use the USB interface most often out of the DDC. Hence my question was focused on the Iris for computer streaming.  

The feedback I have received so far supports that the Iris would make an improvement and to me be worth the dollars spent. I will likely purchase one.

I will keep all posted as to my progress.  Thanks again! 

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.

@iansr Sorry, I will check out the PM problem. If regarding my BEL amp I replied on that thread. I sold it 4 years ago.

Thanks to all who have responded. Just to let everyone know, I did purchase the Iris DDC a couple weeks ago. It has made an improvement in the sonics I am getting from my living room system. Well worth the price paid (~$500) within the context of the system. 

I am running from my apple laptop USB to the Iris, then coax to the DAC input of my Music fidelity M3 SCD player which I consider a DAC/transport.  It also serves my TV when watching movies via optical to DAC though I haven't run that through the Iris yet. Will give that a try soon.

I live in the country an receive Internet service via Wi-Fi. I am to be supplied with service via fiber optic in the near future. That will change my position on the use of streaming as a source. Will likely purchase a dedicated streamer at that time.

@soix My thoughts as well regarding future streamer purchase. Much would depend on the clock and output availability for that unit.
