I looked up radiosure.com with an online tool and that information says it originates from Moscow which explains the inability to reach it. It could be geoblocked, or just on blackout considering the state of world affairs. Which might explain the absence of Fonzy and other moderators from the different forums. I don't think he can get control of twitter account @radiosure even if he has access to internet. Source: over 2 years ago

You might want to give roon or audirvana a try. Source: about 1 year ago

There's also Audirvana and if you have your music on a Plex server, Plexamp is a really nice player. Source: over 1 year ago

TRY AUDIRVĀNA STUDIO. THEIR HIGH RESOLUTION DIGITAL AUDIO PLAYER INTEGRATES THE TIDAL LIBRARY WITH NUMEROUS USER CONTROL OPTIONS FOR MQA,UPSAMPLING, VOLUME LEVELING AND DAC - AUDIRVĀNA STUDIO. Source: about 2 years ago

· Audirvana: The best sound you can get from streaming (IMHO) includes Remote control software. Source: about 3 years ago

Audirvana is simply "install-and-play-anything" kind of SW and even with native DAC in Macbook Air (early 2015), it sounds absolutly amazing. As I've said before, no real rival in terms of sound output quality. Trust me or try it yourself (they offer a free trial). Also, their motto is "Hear the Difference". :). Source: over 3 years ago
