I bought the 3.5 version a few years ago, and have been thinking what could be next on the Audirvana ladder, any suggestions. Thanks
Peter
You are around more than 2 years late 
I might be 2 years late, but have had no problems with the 3.5 version (works fine, even now). I am upgrading my DAC in a few weeks time, so thought about an upgrade for my music playing software plus I am not a fan of subscription things, I want to own it outright
If you are not streaming, you can try for free Origin and buy the license after
