Zabiaud, if you really want to find out what tubes can do, you will need to think about getting a different set of speakers that are higher impedance and hopefully a little more efficient!
Four ohms sort of works with transistors, but any tube amp made will not be sounding its best on 4 ohms. Tube power is expensive, which is why before transistors showed up most speakers were considerably more efficient.
Actually, four ohms does not work all that great with transistors either. Sure, you might get more power, but the distortion will be higher and you will hear it in the form of brightness/harshness. A transistor amplifier will sound smoother and more detailed driving a higher impedance. Plus, speaker cables are far more critical for 4 ohms- they should never be run distances of over 5-6 feet, wheras with a 16 ohm speaker you can get away with hardware zip cord and it will work pretty good. Something to think about.
