I’m a proud new owner of a DirectStream DAC and loving every minute of it. I have a 2011 Mac Mini music server that currently uses just a regular standard (non SSD) hard drive. I have been considering purchasing an external hard drive to both back up and potentially run my music from. I have the option of using the Thunderbolt connection with the mini…is it worth it to upgrade to a hard drive with that option in terms of sound quality? Otherwise, I’ll just continue to use the internal hard drives until I have a chance to upgrade to the SSD internal drive. Thanks for any help!!
