Oy Vey. Why didn’t you left up the original comment you had after my last reply? Because that comment was perfectly showing the kind of sneering, belittling attitude you had in our failed conversation.
Indeed, there are no true SE measurements out there except perhaps for the max output, which is indeed rather disappointing at around .5V. Indeed in this aspect alone the dongle is twice as good at 1V output, but that only means the dongle will be louder and will consequently drive less sensitive, higher impedance headphones better and not much else.
Objectively or subjectively, in an output levels matched and blind test, possibly no one on this planet would be able to tell them apart, no matter how good their hearing is. And I said possibly not probably. As opposed to your “all-knowing” attitude I admit I could be wrong. Critical listening at JND levels is a skill I only aspired to but never claimed to master.
So, there’s the crux of our argument here. My SE was never as capable of taking control of my HiFiMan 400i (at some point in time a Stereophile Class A component) drivers as my daughters 6s was. But using my Thinksound ON2 (another Sterephile Class A component) instead, told a completely different story: there was virtually no difference between the phones, apart from the 6s being able to drive the levels up to painful levels quicker.
So BOTH the available measurements and my personal experience with BOTH the SE and the dongle support exactly what I was saying all along: the SE was pretty far from being total garbage. Are there better solutions out there? Sure they are.
And speaking of casually dropping HiFi rag names around, my experience with What HiFi was disappointing, I’ve bought a Class Product of the Year Award winner based on their recommendation, which I found merely adequate and not really worth the praise lavished on it. Again, my subjective experience here. Stereophile, while also pretty controversial, at least does and publishes measurements.
And speaking of measurements, here’s the link I used as reference for the dongle:

Peace. I’m truly out of our conversation now. Your floor.
