The O2 + KGSS was what made me fall into the electrostatic money-pit last summer. I didn't realize O2 prices were falling in anticipation of the Mk2 launch in Dec. 2007, and bid too much for a used pair. Then, I needed an amp and was lucky enough to find a used KGSS listed for sale.

I don't have the KGSS anymore, but I would say the O2 + KGSS combination is probably the best deal at a "not-so-insane" price point. I think it is equal to or better than an equivalent dynamic setup, such as HD650 + Zana Deux or W5000 + Zana Deux. Hmm, actually the W5000+ZD versus the O2+KGSS would be a tough choice.

I also think the O2 itself is actually priced very reasonably, especially compared to many discontinued dynamics or the HE90.
