Digital Amps vs Solid State Amps

Has any one compared a fully broken in, quality digital (class D) amp to a solid state (class A) amp. We have a Levinson 333.5. Other than light weight, less electrical draw, and cooler operation, will Class D amps out-perform Amps similar to to the 333.5? We are driving Thiel 3.6's.

Frequency extension, depth, holographics, bass control, treble control, slam, dynamics, staging, detail, mids, etc are it.
