Yeah diminished returns is definitely something to keep in mind in this hobby and others as well. I think unless they're being used daily for professional purchases where you absolutely need that 'min-max', the difference is very subjective to what you value it to be.

I held out on the Blessing 2 and they were already considered an affordable splurge for the longest time as is, and I've overlooked the sale for $270 on Amazon as well as ShenZhenAudio in the past. I think the Blessing 2 were worth the blind buy (though I easily could return to Amazon if I didn't like it) with absolutely no regrets asides from not getting them sooner, and sits well in that price point where I feel comfortable for the value. For anything above the $400-500 price point, I think I would personally have to test drive them for a bit before making that purchase. Especially since the Blessing 2 seems to fill that niche that a lot of people have between the more budget options (sub $200) and the kilobuck.
