To DAC or not to DAC ?

Would agree with the above.  I had a Freya + here and found it...limiting in terms of sound quality.  The preamp stage of my Chord Hugo2 DAC (not TT2, Hugo 2) significantly outperformed the Schiit.  It just sounded more open and less compressed to a point where my wife asked it something was broken in my system with the Schiit in place.  

I am not saying that this is the best solution but a preamp and/or DAC streamer upgrade can yield real benefits.  There are some streamers/DACs that have very good preamp stages and might be worth considering.  You can always add a separate preamp at a later date.  

+1, @ghdprentice.

Sooner or later, you will be back here asking for alternatives for Node 2. I suggest a high quality balanced preamp with internal DAC and Streamer. This will save you headaches and simply your setup. You need something like Aurender A10. Keep in mind, streamer user interface is very important part of the experience. The Aurender has a very robust and easy to follow app outside Roon. Good Luck!

I'd consider a few options:

1.  Upgrade the DAC with a built in Streamer - I upgraded from the Node 2i to Moon 280D and it was a big deal.

2.  Upgrade the preamp to a preamp with a built in DAC.  I used the internal DAC on my McIntosh C2600 when I had my Node 2i after comparing the two

3.  You can get a separate DAC...I've not pursued this path but many folks have.

You have the right idea regarding purchasing a new DAC to use with your Bluesound.  It is common knowledge that the Bluesound DACs are the bottleneck of any of the Bluesound units.

Regarding those suggesting you replace your freya+ preamp, it is true that it is not the highest cost unit, but from every owner and professional review it appears to come as close to being one of the highest bang for the buck preamps on the market.  Maybe change the flavor with some new tubes.

Just be aware that often those recommending you flip your gear to what they have now will have totally different gear in a year or two and be just as hardily recommending that gear then.

DAC in Bluesound is way behind rest of system...Freya+ is great for the price, though for me also not as good as your amp and speakers...
