It's not possible to interpolate the earlier measurements to the current ones using the S/N measurements? I'd hate to go thru the hassle and expense of shipping it in again to see how it currently compares? Topping D30 and Exasound E32 are currently listed?It's in here: https://www.audiosciencereview.com/forum/index.php?pages/Audio_Equipment_Reviews/ but not in the comparison chart. In almost all cases I haven't used the data generated by Amir's old analyzer to keep the comparisons accurate. A few times I used the output impedance numbers, and headphone power once.
