A review of the TB-100 has been published on Analog Fellowship.

Here are some excerpts from the reviews:

“Quieter, more Control, Articulate, Resolute and of higher Resolution thus more Detail”

“Rich, Warm, and Dynamic sound.”

“Surprisingly, Balanced, Natural, Organic sound, with a Tube Warmness, Richness and Seductiveness.”
