Klipsh Image X10i. Great bass, and very smooth and detailed sound over all.
No argument necessary, just pick one up.
Well, I'm more into analytical signatures to an extent. MTPC is an excellent mix of fun and analytical.
imho the mds have plenty of quantity and quality but does lack speed which is evident only when listening to bands such as devildriver, job for a cowboy, i killed the prom queen etc. but for linkin park, or any dub step stuff it's perfect:)
On sub bass quantity and quality you should end your search at the Future Sonics Atrios M5 (new version with MG7 driver). Excellent sub bass and no bleed into the midrange (no mid bass hump).
