No kidding! Thanks Amir!

I now politely suggest that we nudge this thread back to its original topic: The (now discontinued) Neurochrome HP-1. Questions related to the HPA-1 would fit better in the TCA HPA-1 review thread.

Yep, Let's go! Do you have something to say about the supply noise of neurochrome hp-1 at this time?

No. The HP-1 reached down around 900 nV RMS noise floor (20 Hz - 20 kHz) so whatever noise on the power supply wasn't making into the audio band on the output.

Just picked up a HP-1 from a seller on Reddit. Supposedly it’s the same unit Amirm measured.

So far it sounds great! I’m going to drag it to work and compare with the 789. Not really a productive reply but I’m excited.

Good to see the HP-1 is still going strong.
