Here is a review of the Storm Audio:
All measurements are 0 dBFS input.
Take always:
- Audioholics is now also using SINAD (a direct nod to ASR)
- All measurements are stated to be at 0 dBFS
- AH waited to get a firmware update to boost analog mode from 100 dB to 110 dB SINAD, Gene expresses that this is expected of a SOTA processor.
- SINAD measurements 91 to 97 dB SINAD from 1 volt to 9 volt output.
Storm is far more expensive than the XMC/RMC processors.
Please do not shoot the messenger but I think it is is important to understand that SINAD is gaining use as a method of expressing THD+N.
And 0 dBFS input signals are used by ASR and Audioholics for measurements.
For a business/marketing prospective, more in-depth measurements are not happening on 16+ channel processors and, fair or not, it SINAD/THD+N across a range of output voltages is measured with 0 dBFS signals.
I believe the RMC-1 was originally measured with a 0 dBFS input signal, expect the RMC-1 and XMC-2 measure the same across the front channels.
Note that the original RMC-1 measurements with in Reference Stereo mode and the XMC-2 measurements are now take in Direct mode so I would not rule out a firmware change affecting the XMC-2 results.
