Hello Audioblazer. Im familiar with the Watt/Puppies and Sasha and I own the TIDAL Contriva (all ceramic).
Believe me, they have a very fine and deep bass. You even can make some corrections related to your room.
They do not emphasize bass but give a very realistic deep en speedy bass and in line with the (for me) perfect mid and highs. I do play jazz, blues, rock all the time at loud levels with a 120 watt tube amp. I can imagine that a solid state amp is more beefy, but Im very, very pleased with my bass from my Contrivas.
Hope this helps.
Regards Robert
