Going by his rankings it's clear Katz prefers a darker sounding HP. I agree with much of what he says, especially regarding EQ, but his comments on the SR-009 really don't make sense to me. He briefly said something about it sounding "bright and thin" but then lauds the Ether, which is brighter and thinner sounding. I have a feeling he's parroting spritzer's early comments on the SR-009, especially after hearing his comments on the KGSSHV and 007 spritzer mod. It's hard to imagine a professional recording engineer who has all those HPs in front of him and thinks the 009 is tonally off. I know LFF here does remastering work and holds the frequency response of the SR-009 in high regard, and I'm in agreement with him - it's one of the best there is in this regard. The Smyth guys and every measurement I've ever seen are in agreement as well. Good video though.
