Sumo 9 and B&K EX442

Mark do you know what the difference is between the EX442 and the EX4420 other than looks.

Danosol,

Sorry, but I don't know the difference between the two models. Someone recently posted a link under this Amps & Preamps forum to a .pdf file on the B&K amps. If you can find the post, you'll be able to see all the older models. The B&K website may have some information too.

Danosol,

The post under Amps & Preamps which has the link to the chart listing the specs for all the older models is titled "B&K St-202 vs St0202+ plus". If you scroll back 2-3 pages you'll see it.

I used to have a B+K EX442, it was a low hrs factory rebuilt when I got it. It was a very good amp indeed.
But when I later got a Threshold S/150 and a Forte Model6 along the way. I sold the EX442. It was a good amp but not in the same class as the others. Not sure how it would compare to the Smuo 9.

From my experience, the Sumo is more like the older Thresholds, 400A, 800A and so on.
The B&K is probably a little "lighter" and "faster" but not as warm.
From what I know, I'd rather have to repair a B&K than a Sumo. When class A amps blow, they really BLOW. Also, B&K is still in existence.
