Well … they arrived yesterday … just in time for me to set them up, make sure they worked, play a couple of tracks … and then head out to a charity fundraiser for the night … I’ll take a few, basic, pictures in a bit. Running these out of my reference-chain (RME ADI-2 DAC, SPL Phonitor X) for now, in conjunction with a modestly priced ($600) speaker amp (150w into 8Ω/225w into 4Ω, toroidal transformer based linear PSU, solid-state analog class A/B, THX-certified\* - with decent measurements - so likely a fair amount of negative-feedback). Initial impressions are, well … striking … The SR1a are doing things that I’ve not heard from a headphone before. The build and aesthetics are awesome … the best way I can describe it is as high-tech, high-end tooling. Adjustment is easy, and driver-angle has very audible effects on sound and stage. There is actual stage depth. Resolution, speed and impact are remarkable - even off this comparatively inexpensive amp. And they really are neutral. Interface box is running cool (79℉) even after several hours of, shall we say, “spirited” listening. Didn’t expect this off such a, comparatively entry-level, amplifier. I don’t think anything productive is getting done today. --- _[View the full topic](https://forum.headphones.com/t/raal-requisite-sr1a-earfield-monitor-headphone-official-thread/3220)._
