The correlation between decibels and frequency response are actually listed on the Devialet website on the specification tab
16Hz to 25kHz ± 2dB at 82dB SPL | 28Hz to 25kHz ± 2dB at 92dB SPL | 49Hz to 25kHz ± 2dB at 102dB SPL
I am not sure how much he was really in contact with Devialet for information, or just gave that impression as there are some technical mistakes/assumptions, like the USB connectivity you mentioned.
As for RMS vs Peak output. If it is "really" Vmax peak to peak, then that would be 2100W RMS for the Silver phantom. But if it is 3000W PMPO (peak music power output) it is totally a useless marketing measurement that has no calculation one can take from it. Based on my own perceptions and comparisons, it doesn't seem anywhere near close to 1500W RMS to me.
