Just the opposite, JC. Transistor amps provide the bass punch, whereas tubes tend to soften sounds out. I have Mark Levinson amps with Klipschorns and the only thing on the market that would provide a better bass punch would be Khorns with Krell amps. I do not use Krell amps, because Levinson amps have the best over all sound quality, while Krells exceed only at the bass level.
