I’ve already got the BlueSound Node 2. The 2i fidelity-wise is the same. I’m happy with it, but I’m looking at offloading to a DAC to improve the sound even further. Two that have caught my eye in particular are via the links below. The MyTek fully supports MQA, which is nice since I primarily use Tidal HI-FI. The second, the MHDT Labs Orchid especially caught my eye because it has top notch processing and its tube based for a very affordable price.
