XDUoo XD05PRO

[LoneFurrow]

I'm still thoroughly enjoying my XD05 Pro and recently sent my WM8741 DAC module to NP Audio in the UK for some mods. I also sent a Lieewho HD200 opamp card to see what Steve could do. I've just received an update they're now ready for return shipping, so I should receive them later this week.

WM8741 DAC Module
8 x AVX 10uf Tantalum replaced with 8 x Kemet 10uf Tantalum Polymer ultra low ESR
3 x OPA1612 replaced with 2 x OPA2211 and 1 x OPA1656
2 x Elna Silmic II 22uf 16v replaced with 2 x Audio Note Kaisei 50uf 16v caps

Lieewho HD200 Opamp Card
4 x 100uf 20v poscaps replaced with 4 x Nichicon KZ Muses 100uf 25v
4 x 0.1uf 50v Kemet SMR Film caps

Before and after pics attached. I'll report further once I've installed them and given them a few hundred hours burn-in.

thanks my friend! For some reason I thought someone else made that Dac and not Xduoo

New R - 2R updates! The official team told me I’ll get the R - 2R test board around June 5th. I gotta help ’em test the sound and bugs, then send feedback to the engineers. When I get the test board, I’m gonna try to ask the engineers if I can take the shell off and snap pics of the circuit board layout to share with y’all. But I have no clue if the official team will be cool with that.

Here’s the lowdown on the R - 2R sound based on early testers’ feedback:

1. Sound signature: It’s somewhere between the AK4499ex and WM8741 (ROHM) in terms of tonality.
2. Soundstage:: Width is narrower than the ES9039, similar to the 4499ex, but it has more depth. Feels more layered and immersive in the vertical dimension.
3. Timbre & musicality: Hands down the most musical sound so far—warmer than the ES9039 but cleaner than the ROHM. Details are crisp and plentiful, without sounding harsh or sterile.

You mean BD34301 or the Wolfson?

Why does this sound like what the Wolfson does? Will be interesting to see how both of them fair against each other; especially with Steve's mods.
