Thanks for your description of the VOCE and BHSE.Curious how do you compare the Susvara and Raal to the TC and th900? The th900 and Susvara have been on my short list. I had a Fostex th00x and thought it was a very fun headphone for EDM. Wonder how the th900 compares. Have never had the chance to listen to a Susvara. However I wasn't totally in love with the HE1k or HE6se. A little to bright I guess for my taste. Like the Edition X however.
The th900mk2 actually is the only pair of headphones I've listened to that have comparable bass to the TCs. The bass is really that good, and you can drive it off of a DragonFly (which is pretty crazy).
My 2nd favorite headphones are the Susvaras (behind the TCs). That wasn't the case until I got the WA33 EE JPS though. With the standard WA33, I felt the Susvaras were missing something. I don't know if it's because of the Elite components or the JPS wiring, but whatever it is, it is very good.
From your description, I think your VOCE has a similiar sound signature as the Raal SR1as. They are super fast, very detailed, but low on bass. If all I had were the SR1as, it wouldn't suit my needs; they are definitely a 2nd or 3rd pair of headphones to have and not the sole pair.
