I preferred the Parasound JC 1 monoblocks over the Coda #8 with the Tekton Ulfberhts. The Coda's transparency and musicality are beyond reproach, but it wasn't up to the Parasound's bass and dynamic slam, which ultimately I found more satisfying.
The Ulfberht's impedance drops down to 2.3 ohms in the mid-bass and requires a lot of current.
