Tried other settings on the RME, different Ref level, different volume, result were all close to 89-90 dBA SNR. I don't understand why I couldn't get anything better than 90 dB. I expect to get much higher SNR and SINAD from a high end audio interface like this RME ADI-2 Pro, at least on the 100 dB range as it is still within the sensitivity range of the QA401. What I don't understand is, measurement showing only: RME ADI-2 Pro Output level was set to +4 dBU reference level, and volume was at 0 dB. The QuantAsylum QA401 negative inputs were terminated using 50 ohms BNC termination.

Hopefully I post this topic in the right place. Hi All, newbie here looking for some measurement guidance.
