Always a hot topic in the susvara thread. I'd just use the search function over there and go through the image gallery. IMO it won't make a difference because the arya is pretty easy to drive on competent head amps. What do you think a speaker amp will give you that your burson won't though ? IMO, its largely overblown and literally when people are destroying their drivers due to user error.
Have you been listening to your burson exclusively have you gone back and tried your K9pro again ?
It was more of a curiosity because I was just having a hard time wrapping my head around the concept, rather than something that I was going to try with the Arya. At 94dB and 32 ohms, they are pretty easy to drive and I find that the Burson is plenty of power for the Arya.
I have been exclusively using the Burson, I actually ended up selling the Fiio to a local buyer over the weekend. After extensively listening to the Burson then briefly going back to to the Fiio, I just realized there was no reason to keep the K9 Pro. Great unit, especially at the price, but a bit of an afterthought to the C3XP.
Also, curious to hear your thoughts on the Susvara vs the Arya, @Tachyon88 !
