Thanks. I read through all the posts on the 3A Circle, and saw that a lot of people have mated the de Capo i's with low-power SET amps. No-one, though, mentioned the Ladyday amp. The Ladyday puts out a bit less power then many other 300B amps, but supposedly has more extension on top (due to some innovative circuitry designed by Thorsten Loesch that's incorporated in the basic WE91-based circuit)...hence my curiosity about the impact of using that particular amp on tonal balance and overall sound. I may listen at lower levels than you; I'm using the Ladydays with a pair of Avalon Avatars now

(I know, I know -- with low sensitivity and funky impedence, Avatars should not sound good at all with 8 watts, but I'm getting ready to move from my apartment and too lazy to unpack my ProAc Response 2 speakers, which are very SET-friendly), and despite an 84dB sensitivity, I'm getting more than enough output in my 20 x 12 living room. Granted, I don't turn it up to shake-the-room levels...living in a small NYC apartment, I try to be courteous to my neighbors, who probably don't share my musical tastes.

Anyway, theoretically the de Capo i's should be a much easier load, so I'm not concerned with sound quantity as much as with sheer tonal quality.
