I can't imagine how a transistor amp could be preferred on a speaker like the Klipsch- unless one has never heard a decent tube amp! First off the Klipsch doesn't really play the bottom octave, so the idea that a tube amp would have less punch is irrelevant, not just because of the frequencies that are audible but also because the Klipsch is a very easy load for tube amps so there is no advantage that a transistor amp will have with 'current' *or* bandwidth.
Perhaps you might actually try a few of the better tube amps- Klipsch speakers certainly have the reputation that justifies a decent amp for them. Good quality output transformers are rated to 5Hz and a lower powered amp (under 50 watts) will have no trouble having bandwidth.
The idea that transistors play bass better than tubes is a myth from the bad old days- 2 or 3 decades ago. If you allow a story like that into your head you will miss a whole world of possibility.
