The Hafler Diablo 9505 was designed by the same person - Jim Strickland and is 250 watts/channel. It uses the same TransNodal circuitry as the Accoustat TNT 200 but with an improved, balanced input section. This amp was made until quite recently (it may still be manufactured under the Hafler professional line). I use one myself and love it. Retail was $2200.00 and you should be able to find a used one for about a kilobuck. Don Laby
