Question for seasoned experts: in what ways can an underpowered amp paired with power-hungry earspeakers affect listening experience?
Context for my question: I have no idea what I'm doing, and it's best to be honest about that. I'm in a unique situation where I could get "best" headphones, but I'm neither an audio engineer nor someone with unlimited funds. I recently got a pair of x9000s and, after much trial and error and trading in purchases in order to upgrade, I made a plan: start with the x9000s as the strongest link in my chain, and build a setup from there.
Current setup: Node 2i, RME ADI-2 DAC, SRM-353x, x9000s
I think I need the Node, for now at least--I get different sound out of my PC when connecting via USB, all my music is streaming, I don't need a Roon for mobility etc., and I don't know enough about streamers to make a different decision. I know I need the RME--it solves so many potential problems that go beyond just being a good DAC.
The 353x is an affordable placeholder while I try out various amps and make a more long-term decision. What I want to better understand is what happens to a pair of 'highest end' earspeakers when they're used with lesser-grade amps. I have no frame of reference to answer this question. I hear a lot of distortion at high volumes with the current setup, and not as much clarity or separation as I hoped for, but I have no idea whether this is a result of the 353x. I will personally test out several 'top' amps over the coming months, but it would help a lot to know what I should be listening for, besides 'more power.'
I've been on Head-Fi.org a lot over the past 2 months, and while I've gotten plenty of good advice, I've often enough been advised to buy stuff by thinly veiled salespersons to understand that Head-case.org might be a better fit for my question. And, I've emailed Spritzer enough over the past month that I want to avoid annoying someone I genuinely don't want to annoy. So I posit my question to the community-at-large :)
