I heard and read many positive reviews about the Adris Dream series and I wanted to give it a go. I also bought a Waldorf edition soprano for my partner and I had a chance to play them both and compare them.
The feeling is of top quality, I'm not particularly keen on the darker coloured wooden rings, but that's a subjective view about aestetics. The sound is magnific: warm, sweet, powerful. A bit loud, but of course you would expect that given such a wide open bore. You easily hit the notes and the low D and C are just a pleasure to hear, with the instrument vibrating in your hand.
I still have to add antikondens liquid as the windway is so good in absorbing the moisture.
The original price as indicated by the manufacturer in my opinion is too high when compared to the quality of the Waldorf edition - which to my ears sounds identical and costs 77 vs 130¤ (as of now on mollenhauer.com) - I appreciate the royalties to Adriana Breukink, but it cannot be justified. The price I paid on Thomann is instead fair.
