Haha, I know what you mean. Personally my favourite is the feel of the rumble.
Edit : I actually got a diy push-pull subwoofer after reading that the CKR9 design was based on subwoofers. They sound incredible
The CKR9s had a very tactile sound that exceeded most gear I've heard. You could feel the sound. I guess you can call it impactful. Maybe that's why I don't like smooth sounding gear.
But the CKR9s have been dethroned recently by the Hifiman Sundaras and Echobox Finders in that department. Both are very articulate and realistic sounding.
As much as as I like the CKR9s though, it wasn't perfect. It lacked a bit of detail and treble extension. I do feel that the Finders are better overall. It's bass may not go as deep nor is it as controlled but it has better treble. The Sundaras lack the weight and power of the CKR9s in the bass but exceed it in every other way. The instrument separation is the best I've heard. I'd say HD800 level but not as thin sounding.
