I'm not sure I prefer one over the other--I think I'd ultimately like both for the LCD-X. One guy brought a SS Krell clone he built--it was beautifully transparent and powerful--GSX mk2 territory. He also brought a modded WA2 and damn if it didn't sound good with the LCD-X. My eyes popped when I learned it was an OTL amp. Lots of home-brew tube amps and most of them sounded very good with the LCD-X.
