Similar sentiments. I use the Susvara more than the HE-1.An HE-1 tuning with Susvara technicalities would be the Susvara 2 for me. Biggest complaint that I have with HE-1 is the soundstage being a bit intimate for my tastes. An in-between bass tuning from HE-1 and Susvara is my ideal one though
I believe that with the right chain/eq , the Susvara can sound eerily close to the HE-1, while keeping those advantages over it.
