I got this amp along with the HE-500s to jump into the audiophile scene. My first impressions are that this amp is made with care. It is a solid piece of equipment that is classy looking with no frills. It really drives the HE-500s well. I haven't had too much time to spend with them yet, but whenever I do have some time, sitting down with this combo is really a joy. It is noisy with my Denon ah-d2000s, but Schiit even says it wasn't meant for Denons so you can't fault it for that. I haven't gotten into tube rolling yet, but it's only a matter of time :)
Overall I am pleased with my purchase and would recommend it to anyone to pair with the HE-500s. From what I've read on here and through doing research it seems to be a very good value and I expect it to last a long time.
