I own the Daline 6.1's and bought a friend a pair of Cobalt 810s. The Cobalts are more in line with the Dalines in terms of sound and quailty than the chorus. Neither the Chorus nor the Cobalts are transission line. As such the bass is not as low. However both the chorus and Cobalts are great sounding. The Cobalts are bit more transparent, sweeter and deeper in bass than the chorus.
