That's a very good point and while thinking about the Storm, the Sus would be my headphone equivalent. I demoed it this year at High-End Munich and I really loved it. It was powered by an ifi amp that (I think) was in the 2-3k price range. Many suggest the Bakoon amp, costing even more than the already expensive Sus... held me back from considering this HP. Btw. I was amazed how comfortable they fit vs. my HE1000v2 Stealth I had back then. Also the sound was very different.
Regarding other amps just sound a little different and not necessarily better is something that also came to my mind on different occasions when comparing DAPs, amps etc. Sometimes I hear no difference, at all. Sometimes with a great pair of HPs or IEMs, they sound just "differently great" to me.
I'm one of those crazies in the Susvara + Storm camp that loved the Bakoon amp too. I recently sold it and got a holo bliss to match my holo spring 3 but I still really love that Bakoon amp and its looks.
That said, I use Storm with DAPs and not so much on my desktop setup mostly because I don't want to extend to a large long cable with an IEM as its kind of awkward.
Coincidentally, I was just in Munich, but now I'm over in Oberkirch in the Black Forest on a business trip, and enjoying my Storm with the Fiio M15S in desktop mode. <3
May be back in Munich area next month, and gotta decide what my traveling IEM buddies will be.
