Conrad Johnson matches well with Aerial. I used to own a pair of Aerial 7b's for several years. I matched them with a Conrad Johnson 2500A solid state stereo amp, a Bat vk5i tubed preamp (with early 1960's NOS 7308 Amperex white label PQ USA small signal tubes & 1958 Tungsol 5881 power tubes), and a Meridian 508.24 cd player (with a Shunyata original Black Mamba powercord). It was a very musical, dynamic and involving system. Nice speakers! Stan
