Integrated Amp upgrade path

Yamaha’s “not good” for his system?  Care to qualify that statement?  
It’s a digital source, format and features matter more then price.  But go ahead and waste your money, op mentioned that “data is data” so I’m assuming they aren’t a sucker.

Why are some components not considered a good match, provided the input requirements are met?

I have a Moon by Simaudio 280D with MiND2 a significant upgrade from my Node 2i and the DAC in my C2600 preamp. 
Lots of options of course depending on your budget. And the Boulder DAC/preamp could be an option too.

Not trying to be rude, but are you serious?

@mrklas - I’ve heard nothing but praise for the Mind2. Can you elaborate in what way it is better than the Node? I would love to audition this component sometime in the next few weeks. 

From someone who started with a bluesound node 2i and then added an external DAC and then moved on to an Aurender streamer I can say without hesitation... it all matters.  The streaming source matters and the DAC matters. Cheap streamers with lackluster interface apps are just that. If they fill your needs and satisfy your use case then knock yourself out. Why would you spend more? That said, I have yet to meet someone who made the jump that regretted doing so.
