I really enjoyed Audirvana as far as sound quality goes. However, Roon's user experience and interface was super impressive. I had been using Audirvana for quite a while with my last amp. When I got the new amp I experimented with Roon. I really enjoyed it, but it didn't sound as good to me as the built in streaming software of the amp. Ended up cancelling my Roon membership prior to the end of the free trial. I noted in my reason to cancel that I wasn't pleased with the sound quality. I actually received an email from someone at Roon offering to extend my free trial and help walk me through the program to get the best sound. Never took him up on it, but was really impressed with that kind of customer service.
Apple iTunes or What Else
My Apple iTunes has 2500 CDs or records on a separate hard drive on a Mac computer. All the music is in AIFF files, and the sound is excellent. The music is streamed wirelessly using Apple Airport Express. My amp is a current Rotel Integrated with DAC and capabilities for optical or coaxial. I use both depending on my mood. The speakers are Monitor Audio Gold 100 which I love. My question is: " What other software would one recommend if I wanted to move away from Apple iTunes. Not dissatisfied but explore a change. Software must operate on Mac OS system.
