Will a wireless streamer add problems to a signal coming out of a computers USB output?

Wireless to optical does not compute. You’ll never get there with a laptop and a D2.

Start over.

I almost went that route before I got my first actual music streamer for $200. Never look back or a pillar of salt ensues.

I can accept what people are saying. I’m actually contemplating a Simaudio’s Moon Mind 2 streamer, which of the ones in its price range seems as though it would serve me best. I had thought I would try a piecemeal approach where I ordered the Pontus2 first and experienced how that improved things, and then add the streamer if necessary. What I’m hearing is that it is totally necessary if I want to get the benefit of the better DAC and fully utilize my great speakers. So perhaps my experiment is doomed because I will have spent a bunch of money on the pontus, which is in shipment, and I won’t be able to tell how much difference it makes because the signal path will still be crappy in front of it.

Does this line of thinking makes sense?  I have some extra money right now and don’t mind putting it toward upgrading as long as the upgrades will be quite noticeable. My wife especially doesn’t like spending money unless there’s a good bang for the buck, and she needs to be able to hear the difference; she does not have audiophile ears. Maybe some of you can relate to this… 

Not sure, but I do know that mine interferes with my tubed phono preamp, as it sits about a foot away. I tend to just unplug the streamer and that solves the issue. I’d move it further away, but I like where it is for convenience and the fact that the interconnect is not that long.

I took a leap by buying  a streamer to add to the dac I just bought. Thanks for all the help.
 

Congradulations! Good move.
 

My streamer is the most expensive component in my system before (and equal) to my amp… well worth it. You can’t recover or reject what comes from the first piece in your audio chain.
