Hi, I need a preamp to put betwen my imp-400's lineout and my home amplifier ...
Without a preamp, the sound is very quiet...

I'm looking for a diy project with as little parts as possible, for example something simular to C-moy (1 op amp and some capatitors)

If there is a possibillity, post a diagram and maybe a board layout?

Cheers...

why not just build a cmoy? it would do the job quite well.

I allready have one (C'moy that is)...
So, is that my best bet?

Cheers

by far not the best bet but it will do the job within the requirements (simple, and small).

It's probably worth using a different opamp then the opa134 though. An OPA627 would be the logical step up. Others include AD8620, OPA2227 OPA2604 OPA637 (if u can get it working).

A simple cmoy is all that's needed as the output wouldn't require much current.
