I currently have a Weiss Dac 204 with a Modwright linear power supply. I have found that upgrading the DAC brings out music that I didn’t know was on the recording. The 2 contenders are the Meitner MA3i and the Berkely Alpha Dac Series 3. I am leaning toward the Meitner MA3i as it comes with a network card to allow for streaming.
Do you like the DAC204? I home auditioned one with a Lumin U2 Mini. I thought it sounded quite good. I decided instead to get a Weiss DAC501-MK2 and forego a streaming transport. The DAC501 has an ethernet input for UPnP and Roon support. Roon is all I need, so I didn’t bother to get a streaming transport. I bought a WiiM Mini for $90 just to add Airplay2 for the rare occasions I want to use that (e.g. for Youtube from my laptop).
I don’t know what your budget is, but have you considered the Weiss DAC501-MK2? It’s very significantly better sounding (and more capable) than the DAC204. It’s the best DAC I have ever listened to. It also has DSP built-in if you want to use that. And it has that network input for UPnP and Roon.
I’m really more of a vinyl aficionado, and the DAC501-MK2 is the most musical sounding digital I’ve ever heard. It’s very analog like, IMO.
