Have never listened to radio paradise. If my sound stage got any bigger it would be out of proportion.
I started out with a BDA-3.14 (which is a BDA-3 with a raspberry Pi internally, hence the 3.14). The internal streamer kept on locking up. Talked to Bryston and fat story slim they replaced it with a BDA-3 (free. no shipping either way, no tax) amazing customer service.
The thing I did like about MM (via a pc) was that it simply gave the URL to the 3.14 and then stepped out of the way. No music going thru a pc.
The Nucleus+ is outputting a digital stream to the BDA. I can't say where it lands on the good, better, best scale. But it sounds fabulous through my system which includes a Ref6 and a bunch of Pass amps.
Yesterday I received a Roon Nucleus Titan, not in the system yet. I bought it because I am going to "try" to use the built in room correction and wanted the additional processing power it affords. Weirdly, to me, it came with the Titan and a power cord and nothing else...zero, nada, nothing! I guess they expect everything should be done on-line.
