Active filters? (Off Topic)

Hello Carles,

I wan to know the opinion of the forum members about the use of external active filters (analogic BSS-318)instead of the passive filter normally used.

Do you recommend it?

In general an active system can perform better than a passive filtered system assuming that people know what they are doing of course...

Passive parts do have their negative influence to the sound though (any part or extra connection is taking away something nice), if it should be recommended depends on the compromise as nothing is perfect.

Not much help eh?

How are you going to use your active filter? What are you trying to gain while using it?

If you forgive me Bert, doing caps, inductors and resistors that are being used in passive, active and digital filters by clients, I've created the following rule of thump: The part will have an influence on the sound regardless of the filter being passive, active or digital, what matters most is that the filter type is done correctly. A properly designed passive filter sounds better than a bad active and vice versa. On the matter of less is more, I don't per se view the active solution as less but rather a different approach. I agree wholeheartedly with your comment regarding the relevant compromise being the determinator, nothing is indeed perfect.
