vandys and tubesfor what it's worth, i have vandy 2cis, soon to get 2ce sigs. i have the quicksilver 60 monos and i have no trouble at all driving the vanys in my small room. in fact, the volume control is way down. and i have 30 or so tube traps in there to suck up bass etc. i also love the vandy sound. i almost went to audio physic, because of the detail, but i'm afraid i might not be able to live with the etched sound, in the long run. the vandys have a slightly more veiled and distant sound, which is ok with me cuz i sit further back at the concert hall anyway, and their tonal balance is soothing and accurate from a distance.
