Is JRiver still the best software?

Finally got around to curing a nagging problem with my MacBook Pro (13", mid-2012) that had stalled my converting it into a music server.  Looked back into the advice I got here several years ago on the matter, and JRiver was the top recommendation.  Is that still the case today?  I'm running OS X Catalina on a fresh install and will be feeding a McIntosh C50 that accepts up to 32 bit, 192 kHz PCM input.

Thanks in advance for the benefit of your wisdom!
