What software to play .dsf or dsd files for Windows 10?

J River is a one time payment but you are better off by buying each new yearly update as it is not too expensive and little buugs are sorted out with each new update. Regarding file playing you can tune J River to upsample all files regardless of what they are to play as DSD through your DAC which is what I do and they do sound very good that way.

I have just taken out a trial of Roon and I have to say it far outshines J River which I have used for two or three years. The main differences are it is far more detailled and dynamic, files have got a new life in them that was not noticed with J River. and J River now seems dull and coloured by comparison. I do not like the cost of the Roon package it is far too expensive and it's a devil to get your head around it, I suppose that is because I am now over 65 and tech is now getting more and more difficult with each passing year. The short answer though is I am going to keep it despite the cost because it is a night and day difference in quallity.

coach59, I agree with you also that the music is all but unfortunately we have to learn the tech so we can sit down and just listen. Yes Roon is also full of crud and all I really want to do is go into a hard drive select a music file , select to play it in Roon and sit back and enjoy but it is not that easy. I am staying with it because of the sound quallity but I just wish they would make it simpler.
