@ghdprentice Another time I totally agree with you. If the speaker is both efficient and an easy load, I use a 30 watt tube amp on it. I disagree with @james633 My second system Signature IIIs sound equally great with either my superdeluxe voltage regulated Dynaco ST70 (30w tremendous bass), my EAR 890 (70w) or my tube monoblocks (125w) A little sweeter sounding with the Dynaco though.
