I've been enjoying my Studio 2Pi Towers, hooked up to my custom Dynaco Mark III, for the past 12 months... Overall, I am satisfied with what the 2Pi Towers can deliver, except I wished there is a bit more bass... Anyways,I am thinking about building another pair of speakers for stereo application and move the 2Pis to home theater use.

So here is my question: After reading the archive about various 4Pis it seems that the stage 4 Pi is the way to go, from a pricing perspective is the stage 4Pi three times better sounding than a 2Pi Tower ($80 vs $285)?
Also, for the folks that has both 2Pi Tower and 4 Pi I am interested to hear your recent thoughts about the two speakers...

Please help me choose my next project, something that is better than a 2Pi Tower without breaking my piggy bank...

Thanks in advance.
