I'd say side-by-side and most importantly volume-matched A/Bing is very important, whereby long-term auditory memory can be quite unreliable. I also didn't notice any consistent differences with quite "demanding" tracks like the works of Susumu Hirasawa or those produced under P-Model. But I am accepting of people having the pleasure of partaking of experience-enhancing suggestions that I am rarely able to enjoy. I have so far only really been astounded by EQ profile iterations and amazing recordings. And I would be doubtful that "upgrading" from the FiiO K9 Pro ESS and its balanced output would change these impressions.I know we all perceive sound differently but I’m quite surprised to hear those impressions after an A/B comparison. There could possibly be some unit variation going on or maybe just differences between our source/signal chains.
I currently own the Arya SE and previously owned the HE1000se for a few years. I didn’t own them both at the same time but there is absolutely a difference between the two in my opinion.
To me, resolution, separation, and positioning are all cranked up to 11 on the HE1000se. Impact is really good as well. The Arya SE sounds like a “baby” HEKse to my ear which might be what HiFiMan was going for. The Arya SE is very detailed in its own right but not nearly as resolving as the HE1000se IMO. This may be preferred by some because the detail retrieval on the HE1000se can actually be too much at times haha.
I’m actually going to upgrade from the Arya SE to the HEKse in the near future. I miss all that detail!
