Thanks Amir! Looks like a standout speaker.
Revel M106 ASR vs
Harman Spin comparison, corrected the ER curves from the NFS for the Harman-style computation. Omitted the on-axis for graph intelligibility:
Good agreement up to about 4-5kHz, after which Harman shows about 2dB more energy. I think this has happened with a few of the Revels, I wonder what's up with that, especially after the super-old infinity showed basically perfect agreement.
Edit: And here's the M106 vs the IL10 (Listening Window in white)
You can see the relative lack of energy in the upper mids in the IL10, but idk if enough to explain Amir's different impressions.
