I think its just a different level of experience here. An experience audiophile who has been playing around various equipment, cables, dacs/amps over many years and decades will have a different perspective of another who has just started in this hobby. Here I think the key differences is the level of appreciation..
Here, here. When I first started in this hobby on this site, I assumed that because I couldn't hear it with my HD600 and Cosmic Headphone Amp, I thought either my hearing was poor or the people on this forum were snake-oil salesmen. I think there are outrageous claims out there, but there is a significant amount of learning before you can appreciate the extra 1%-5% that a good DAC/amp combo can get you over a basic iDevice (which I think the Shure 846 was tuned for).
Do I regret ever getting to the point where I want to milk some more out of the Shure 846? Yes. But I'm here and it's hard to go back. That extra percent does add to my enjoyment.
