Hi AT - I've been having a play with some ECF80's which were very kindly loaned me be someone on the 'Wam. I had a pair of Telefunkens in my old KEL84 which worked very well - the same can be said here, and more interestingly there's a pair of old Brimars which are also excellent. A very noticable improvement on the std Edicrons and the CVC's I've got lying around.

The problem though I feel is that the KaT doesn't really like the Royds - they really need a good dose of solid state power to wake them up, and sound somewhat sluggish and diffuse when the KaT's asked to deliver at higher volumes. That's not the amp's fault of course (my friend uses this 34 to drive ESL63's into which it sounds truly wonderful) but more a speaker-amp mismatch. I'm looking forward to trying Mike's 88VA soon so we'll see how that goes. If that floats my boat I'm going to have a go at building my own one.
