The "magic" of tubes will come from properly matching the amplifier, speaker cables and speaker. Otherwise you may find more trouble than magic.
If your speaker impedence is uneven, if your amplifer's power supply is not strong enough, if your speaker cables are not revealing enough, etc., you could end up with results that are less than optimal and maybe not enjoyable. I am a devout tube lover (of the sound, that is) but I have speakers that are friendly to tube amplifiers and I use the most revealing speaker cables I wanted to afford.
If you're going to be "experimenting" with tube electronics, I suggest you find a dealer willing to loan equipment or some friends with tube amps.
