Looks like the USB # 2 isn’t supported with the Roon Nucleus for USB 2.0 for 24/192 resolution on my Cambridge Audio 851C, I can only use Audio USB 1.0 (max 24/96). So I’m looking for a new DAC (do not need headphone amp but understand most come with it), I would like the DAC or network player to be on the Roon Ready list and Roon in house list, and perform at least up to 384kHz DSD256, price $3K-$4K, with XLR balance out connectors, I have narrowed it down to two DACs so far, the Moon SimAudio 280D or the Auralic Vega G1, but also open for suggestions. I also wanted to see if anyone has these units and can share their experience with the device. We use Qobuz, Roon Nucleus, with USB for connectivity. Stream majority of the time.
