Peter_s,
My current amplification is a Jeff Rowland integrated, and before this a Plinius 9200 integrated. The rowland was a big jump from the Plinius, and the Plinius was no slouch, but in both amps, the relaxed treble character of the C1 remained. Please note I am speaking in relative terms, as the C1's top end is probably considerably more open than other relaxed sounding speakers. But compared to speakers like the Diablo or V2, where the top end soars and electrifies, I felt these speakers are able to better convey the intensity of some instruments like guitars, drums, cymbals and even piano. Even voices are subtly better rendered.
Hessec,
Nice thoughts on V2 vs. C1, that is helpful. It is interesting you mention the C1 has more bass slam than the bigger V2, to me this may be a plus given my acoustically challenged condo living room. When you say it took you a while to adjust to the sound of a sealed box, can you explain further. Also in terms of ease and flexibility of positioning, w/c is a strength of the C1, how did you find the V2?
