@M0N, have you heard the Rosson Rad-0?

I recently sold mine lol, wasn’t the greatest fan for the price

Haha! Didn’t like it?

Not for the price, no. It sounded good but had some flaws that I ended up much preferring an audeze

Yeah, something about Audeze…

Rosson’s design lab has the RNHP.

:speak_no_evil:

Lol, yeah isn’t the guy that designed the rosson from audeze? He somehow didn’t live up to the higher end audeze in my mind

Yup. Alex Rosson co-founded Audeze.

He has a music industry background as an engineer.

His Rad-0 sold really well. They sell out as soon as they’re listed.

And that his first headphone, so…

Yeah, I just didn’t really like it that much tbh, it was just alright, and didn’t really have a place in my collection especially at that price

I’m really looking forward to your impressions on the HEDDphone. :thinking:

Is this what you’re looking for?

Yes


Edit:
Looking at the various datasheets, it is simply impossible to get balanced out of this.
Application schematic as per TI (exact implementation as in the RNHP):


Clarification: You could run two of the main amp stage (1 per channel), but then you make the whole input section trimmable…
