IMO the K1000 with ears flipped and K701 have a similar tonal balance...yet somehow the exact same tonal balance comes off as a cavity resonance in the upper midrange in the K701, but the exact same frequencies on the K1000s can have the same amplitudes as the K701, but there is no cavity resonance in the K1000 as there are no cups...IMO, instead in those same upper mid frequencies on the K1000 is heard as "true" soundstage depth. Its hard for me to explain, but because of the cavity resonance in the K701, the K1000 comes off as more linear in the frequency response, even though IMO they have the same response in the midrange. In other words, I actually agree and disagree with your statement at the same time.
