Eric, thank you again for a great review. Not being an NW fan, it is still interesting to watch the quality reviews that you provide.
With that said, can someone reference some time points in the video to explain the "sounds changing from simple to compound"? With all the comments over the years I thought I would be able to pick up on the difference, but I can't.
I di hear the starting chuff and I hear the "higher speed" passes that sound like the regular chuff, just faster.
Thanks.
Charlie
