Romy,I might be confused with the passive and active, but from my understanding you prefer your active 834PT to the passive RC network and passive LCR networks. You also prefer the passive LCR to the passive RC. So 834PT>LCR>RC.If I got it righ...

Hmmm - the whole LCR thing, I don't like the idea. I'll admit to having no experience of it, but in engineering terms, it just gives you a constant impedance filter. The EQ is still done by caps essentially, far as I can tell. I see the wh...
