In the UK since the 1970s there has been a strong affection for small integrated units.
There are loads of UK standalone DACs, Chord is probably top of the pile brand. ranging from the $600 Mojo to the $9,000 Dave.
The two main audiophile brands, Naim and Linn, both went into streaming big-time around 2007 and mostly, if not entirely, they make combined streaming/DACs.
Auralic have been very popular here. I’ve had two of them. They are mostly standalone streamers, but my son still uses my Aries Mini and he uses the internal DAC.
The Cambridge Audio units are very successful because they win all the awards and CA is the sister company of our only large audio retail chain, so its a sort of in-house brand. That retail chain is also big on Bluesound.
Then there is the dCS Bridge. A big seller.
When I was interested, Melco, Aurender and Innuos were often referred to, along with Roon Nucleus.
There are so many brands from Denmark, the Netherlands, Sweden, France, Germany, Italy, we are just spoilt for choice. I used Primare for 12 years and they make a lovely little streamer for £450, about $600.
The fully integrated units like Hegel from Norway and AVM from Germany are powerful and expensive. I think the cost of European real estate is an important factoring European design preferences are very different from the USA.
Then you have the Swiss brands - quite a few - lots of aluminium and sharp edges.
