$4500 amp beat out the Tenor OTL in the latest TAS

I've heard some other people giving very good reports of the Hurricane amp. It seems this is a good one from the folks at ASL.

I can't comment on the comparison with the Tenors. But, nobody rides on the top of the heap forever. It was bound to happen.

I think the only reason HP picked the Hurricane as the best amp he ever heard, is because he's never heard my amp. :^)

I think that the big Atma-Sphere could drive them fine, but you'd have to have the impedance matching transformer in line with them. Once you do that, then it is no longer an OTL, because you had to put the transformer back into the line to handle the 4 ohm load. Then you have the complexity disadvantages of the OTL and the disadvantages of the output transformer too. Much of the OTL benefits are lost in this transition. I'd use a straight high power push-pull amp for this application.
