Re: Sierra-1 NrT's !!!
Dave,
Thanks for clarifying the AA custom tweeter difference in the S2 with the 70-10 base RAAL's!
When standing, there was a definite drop in vertical dispersion energy response in the S2's from my 87" sitting position, but my prior 10-20db loss statement was exaggerated...probably more like 4-5db. With the S1 NrT +4 db rise from 7Kh to 14Kh, believe your summation on why I prefer the NrT's in my high ceiling listening room makes perfect sense.
My last audio-metric hearing test (2015) proved I still hear 10Kh at a 0db reference levels...feel very sensitive to any loss or gains in that extreme near ultrasonic region. For me and my environment, the S1 NrT's soundstage and realism still recreate an Amazing and Live 2-channel experience!!
