I felt that the essence STEREO was amazing very musical but could not drive my blades and when pushed actually clippedI am intrigued by this also. I've inquired with several different dealers about the 333 vs Essence separates, and (while acknowledging there may be bias for price heirarchy) there has been a preference for Essence separates. The knock on the latter is bass response, which can be lacking a bit.
I suspect based on personal preference and system matching, the Essence is going to be be more liquid in the mids and highs, while still being neutral, while the 333 iwill be superior in the lower frequencies.
it became evident to me that the class A sonic character was better that AB
The 333 was not as musical but had amazing control headroom and overall was a better amp if I could chose between the 2 its would be the 333
Cause I like a to play my music loud and the essence would not be enough for me
