I’ve got two. Topping D90SE and R2R Denafrips Ares II. They both offer me options when listening and varying experience whilst listening. Topping gives me Bluetooth option to connect, so I can stream Apple Music from my phone, or other streaming services or YouYube. I’ve really utilised this feature, so useful. A great DAC IMHO, and is a very resolving and clear sounding DAC. The Ares II gives me a slightly less fatiguing listen, with more spaciousness and smoothness. Perhaps slightly less detailed than the Topping, but so minuscule a difference. I enjoy both. I bought DACS only, so could pair with different amps. Balanced connectors for everything. That’s my input.
