I can offer my recent experience with my Tannoy custom built HPD 315 (12" Dual Concentric, ca 1975). Ever since I built these speakers, wanting to try an SET 300B amp was high on my audio bucket list.
A few weeks ago, I purchased such an amp, though it is a single 300B per channel, @9Wpc. The amp was originally sold in kit form (mine was factory built), and was designed by Sonic Frontiers.
I found out that only being 9Wpc is not a limitation. My system plays just as loud as with my other amp, a 35Wpc EL 34 based push-pull VAC.
Although the VAC is a great amp, and has had factory upgrades, the SET 300B has taken over listening sessions.
I went back to the VAC, only to change quickly to the SET again.
This is my first experience with an SET amp, but it is a great one. I wouldn't worry so much about the Watts per channel, but on the quality of the power supplies and transformers of whatever amp you are thinkng about.
It turns out, Tannoys can work very, very, well with an SET 300B amp.
I don't know if this helps or not, but I hope you find what you are looking for. Turnberry's are great speakers, I heard a pair being driven by Joule Electra SET mono-blocks recently, and that was great match, so if you get the right SET, I know you will be very pleased.
Best of luck, regards,
Dan
