For me these would be my first planars. I've got a small collection of headphones. DT770s, K7XX, Philips X2s, Klipsch S4is, Sony MDX1000s and even some Airpods. I like the sound of the T-X0 tuning and think these would fit in well with my budget collection as opposed to replacing what I already have.
I'll be running them off a Creative X7, while not everyone's cup of tea, should work well.
