I agree with you there.
The differences are minimal or non-existent in MOST cases. But somethings do appear as apparently different.
For example, the difference between the NODE 2i & CXN V2 were very apparent. The only thing I have been successfully able to pick up in a blind test yet
There were a few others that did something different but not incredibly different. As I also mentioned in my second post of this thread, that even while auditioning I couldn't really tell a lot of difference between various streamer DACs in various price categories, hence I ended up picking the CXN V2 instead of the big money challengers.
Right now in my setup I am shuffling between the following as sources.
1 - Rpi + Hifiberry with Moode
2 - M1 Air USB out (slightly lower output)
3 - Wiim Pro Coax Out
******The DAC being RME
I can not tell the differences enough to justify the purchase of one or another.
Just experimented with Yamaha WXC 50 & Wiim Pro. No difference to my ears at all either thru RME or directly to G3s. I can convince myself of the differences, but I can't decidedly hear them and I will definitely fail a blind test.
In my book however that is a very good thing! Saves a bunch of money experimenting
Thanks!
