Kclone I can only speak for the models I owned which were the 1sc, response 1.5 and response 2.5. I had several amps with them tubes and solid state and always found them very enjoyable. Perhaps I should clarify my statement about the Spendors, this again is based on the Spendors I have listened to, I have not heard every model in either line so perhaps take my opinion with a grain of salt. All I can say for sure is that Proac and Spendor make very musical speakers.
