Different tubes in the Paradisea can have a major effect on the bass levels.
I've found the Tung Sol NOS 5730 equivalent tube delivers a significantly fuller and more robust low end than the stock GE 5730 that the Paradisea comes with. The GE 5730 has more sparkle and resolution to the high end however.
There are other tubes that might be tried as well. Do a google search on Paradisea tubes for info on how various people hear various tubes in the Paradisea.
My Paradisea runs into an ARC sp16 preamp. Not sure of the impedance #s here but I do not find bass levels or definition to be an issue with this particular combo.
