There is more to this than just power output.You will probably need a higher damping factor which is almost beyond valve amps.I understand though that Supratek is developing a KT88 amp with a much higher damping factor[maybe as high as 200].It might pay to wait and see what comes from this.
I have owned and loved Spendor speakers but they are not easy to drive.
