Thanks for your impressions. I tried replicating your chain somewhat with a Mogwai SE and my Valkyria. I've listened to Norah Jones - Come Away with Me and don't really feel the boxiness that you described. Would you mean that the music sounds somewhat constricted and "compressed" into a smaller "space"?Pulsar has finally arrived! For various reasons, the wait was around 2 months for me. Got them yesterday and have been listening off and on since then. First impressions were.... not expected. As I continue to listen, it seems like I'm about to throw a big rock into everyone's blissful pond here because I thoroughly am not hearing the appeal of the Pulsar. For starters, everyone is right regarding these not being ideal headphones for any bass heavy music. There is essentially no sub bass to speak of, and bass is rendered as more punchy than deep. Aside from that, my confusion lies in the overall tonality of these. I'm hearing highs that sound slightly tinny and mids and bass that can be a bit muddy, boomy and even boxy. As I also have the Super Leggera on hand, I can hear the family resemblance, as that headphone also has those qualities. But I assumed that going from their entry level to one below flagship, things would dramatically improve in all areas, including realism. I'm not hearing it. I've purposely veered away from all the electronica I like and am strictly listening to low-fi acoustic with female and male vocals, mostly in the folk and indie genres. Also throwing in a little jazz. I don't generally listen to classical. So far, these have been a mystery. My 1000se and ES-R10 are much more convincing and involving. I can't get away from the general boxiness of the sound. Since I've never heard anyone mention any of what I'm describing, my first thought is a synergy issue with Spirit headphones and my amp. I've got more time for evaluation and I'll continue to listen. I can't imagine break in will change things significantly however. I know @ThanatosVI had his initial reservations, but seems like he's come around to appreciation. I'm not sure I'll get there. I wish I had another amp to try, but alas not the case.
I'm also curious on the bass as I do like my bass. My preferences may not be similar to yours but I would like to understand what you're not able to hear on your Pulsar with regards to subbass, so that I'm also able to educate myself on how others perceive bass. Could you provide a track and specific section?
