You've certainly left a lot to imagination.... absolutely no details as to
what you really want.
What's a 2.1 channel amplifier???
What do you want to amplify? Audio, video, RF, etc.
What kind of bandwidth do you want? Frequency response?
What will be the input?
What will the amplifier output go to?
What kind of output power do you need?
What kind of primary power do you have to power it?
If you can answer those questions, maybe somebody can direct you to some
good resources for your amp... otherwise, it's a shot in the dark.
