Had a go at making this headphone attenuator for the Bravo V2. The details are in there for the Bravo V2 version. After talking with Frans I found two 3.3 ohm resistors worked best. It certainly tames the volume and allows for a larger sweep of the volume knob.

Please recommend me a tube for the V2. I'm willing to build a tube collection so please throw out suggestions. I'd love to hear what your favorites are

I'd love to hear about tube recommendations as well, the ones stated early in the thread are a bit too exotic so it's hard to find...

That sets your output impedance to about 3.3 ohms though. For sensitive cans, I actually have found that -30db (roughly, cant remember exactly) is perfect. (68R series 2.2R parallel) You get better impedance matching with low impedance headphones too. A below 1 ohm output impedance is ideal but that means that you loose a lot of volume.

I use the attenuator that I made on my Xduoo XD-05 plus a lot cause that can deliver 1W into 32 ohms and I try to use IEM's with it lol.

Well, 3.3 Ω output impedance should be plenty dampened by 32 Ω headphones or more resistant ones... so this really would only be an issue with extra sensitive IEMs and headphones.

Also, it’s been a long time since I saw this thread! Wonder how @Judge Buff is doing.
