I agree! Normally 8-Hz is considered the lowest desirable arm/cartridge resonance frequency. However, it also depends on other aspects such as the amount of cantilever damping and also the amount of tonearm damping. For example, my AT-ART7 cartridge exhibits an arm/cartridge resonance frequency in the neighborhood of 6.5 to 7-Hz in my SME V yet it plays well and sounds exceptionally nice on my Sota Millennia turntable, which incorporates a vacuum platter.
I would prefer its resonance frequency to be 10-Hz, but Audio Technica apparently raised compliance without notification. The ART7 is specified to have dynamic compliance of 10 x 10-6 cm/dyne and the ART9 is specified at 18 x 10-6 cm/dyne, but Audio Technica seems to have made them both with the same high-compliance.
I just feel fortunate that my ART7 still works well and sounds good with such a low arm/cartridge resonance frequency. I think it might sound better with lower compliance, but such is life! It still sound better than my Denon DL-S1, which exhibits an arm/cartridge resonance frequency of about 8.6-Hz.
I have written it before but I think it is strange that most combinations today are on the low side of 10 Hz. Even if they sound fine at 8 Hz, they will sound even better at 10 or 12 Hz. The stylus will deflect less due to warps and record imperfections which will improve channel balance and stability of tracking force.
