I was the one who asked if you'd ever heard better or more bass from another set of khorns. Maybe they just don't have it, I don't know. Cd's reach 20hz, LP's down to 16hz that I'm aware of. No idea about streaming but it would seem possible to be nearly uniimited or at least limited only by the original source. I don't stream anything so can't really speak to what it actually can or can't do. I do know that an awful lot of people seem to be in love with it, I'm just not one of them.
Anyway, if you are very fond of bass, it is possible that having speakers that are limited to 33hz, will not completely satisfy you. I don't know but I'm sure I would feel as though I'm missing something, after listening to AR9's for the last 20 years plus. I, like you, hate the sound of flabby or exaggerated bass. I do not get that from my speakers at all. They are very solid performers down to 18hz. I guarantee that it is an appreciable difference from 35hz or so, felt and heard.......distinctly.
If you are in love with your speakers, you may benefit from a subwoofer system. It can be very tricky bringing that into an unrelated speaker system and finding real synergy. I do understand being very fond of the Klipsch sound. It has been very popular for a very long time. You just need to figure out if deeper bass is what you really want or if it's the sound of those big khorns.
