Congrats on the new DAC.While I haven’t heard the T+A DAC, I understand it is very, very good - particularly for the price point. Please let us know how you like it.
I’m not familiar with the streamer you are considering but want to offer a few thoughts. My own experience suggests you will be well rewarded by pairing your very high quality DAC with a streamer of at least similar quality (and unfortunately, expense).
For me (YMMV), going to a higher quality streamer made an even bigger difference than going to a higher quality DAC. Some will disagree, but there are plenty on these forums who have similar experience. There are readily audible differences as you go up the chain.
I suspect you would be pleasantly surprised by auditioning the Aurender N200 (or even N20 if your budget can stretch).. Auralic is also coming out w/ an upgraded version of their Aries G2.x streamer (and G3). The GRIMM MU1 (I’ve heard it - and it is very good). There are many others which I haven’t heard. Perhaps the matching T+A unit would be a good solution.
Of course, you might find in your system that the DAC 200 negates the need for a higher quality streamer. So, an audition is a must. But I suspect, given such a high quality DAC, you could be in for a real treat going upstream.
