I've had good results with eqMac

Yeah the sensaphonics. Obviously the fit is great, but they are also more durable than the standard tips and keep the Etys low profile.

A bit cheaper, but the Oppo PM-3 might be a good fit for you

It varies. Check out the Harmonized Tariff Schedule

Beats for sure

I think the Sennheiser 800s match well with the RME, but I do wind up using it more with IEMs

Have you considered the custom tips through Ety? I had a set made years ago that lasted longer than several pairs of the headphones.

Hard to say without a direct A/B comparison to the ones you call out, but I heard the original Orpheus back in the day at the Headroom HQ along with a number of the other high-end headphones they had on the shelf at the time. The Orpheus was great, but not multiples better as the price might...

+1 on the Matrix Sabre

Unbreakable - 7/10 I remembered liking it a lot more when it came out.

@565hunter - do you know if Schiit has been putting that multibit sticker on upgraded units from the beginning? I had mine upgraded by them and it didn't come back with the sticker. While I'm at it, are there other ways to identify which version I have?

Does anyone have a good recommendation for 2.5mm TRRS female connectors?
