Transparent Audio Digital Coax Cable

Thanks.
indeed helpful advice.
1. I can now buy the Transparent Coax in the USA

so saving the shipping cost to my country.
2. In plan, Upgrade the Blusound to a better streamer.
so the “new” cable will be used in the future.
3 it seems to me that the Transparent cable is superior to AudioQuest

so I’m now in some kind of opportunity to get the transparent

more important, I am using the McIntosh’s internal DAC

not the one in the Blusound ( a Digital connection coax )

The DAC in your McIntosh isn’t that great and the Bluesound Node is actually not a terrible streamer. In your case I would consider getting an external DAC purely for 2-ch listening and for now keep the Node.
But definitely don’t waste money on a new Transparent Audio cable. Your current cable is totally fine within the context of your current system.

Thank you !

Thank you all for a great help and support.
