    Default Audio greetings from Germany - Going active with Najda DSP

    Hi all,

    my name is Hardy and I'm a music lover and an audio DIY guy from Germany.
    I've realised a few speaker projects, but since about 17 years I'm reworking from time to time my latest DIY big 3-way D'Appolito speaker (based on SEAS chassis) x-over network.

    Recently I've converted it all to an active setup, based on the Najda boxed DSP and a Rotel RMB-1506 6-channel amp.
    As I wasn't happy with the out of the box sound of this setup, I've started to experiment with different opamps in the Najda DSP.

    I'm very curious to hear about your experiences with going active and especially with the Najda DSP and recommendations for opamps or other sound tuning ideas.

    Opamps I've tested so far:
    - LM833 (original Najda ingredient) -> didn't convince me at all
    - LM4562 -> better, but still doesn't fulfil my expectations
    - AD8066 -> (currently waiting for the opamp delivery. I've read a lot of positive things about the AD8066) to be checked
    - your recommendation?

    Cheers,
    Hardy

    Oh my god! There's nothing wrong with the bidet is there?

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    "You don't have free will. You have the appearance of free will.”

    “There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”


    ***SMILE, BE HAPPY***

    Hello Hardy. Welcome to AOS.

    DIY projects are popular here. If you have any 'on the go', you could feature them with a blog in the Gallery section or show them in The Drawing board area.

    Take a look around the site and feel free to join in any chat that interests you.


    Enjoy the forum,
    Geoff.
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    Hi

    Seeing that you use the Najda DSP, how do you use it, digital in or analog in?
    Have you build your own or did you buy the boxed one?
    Do you encounter the same things as I do with the Najda, that is overload on the digital input, something I 've never seen with the Behringer DCX2496...
    I hope you dont mind all these questions,

    Regards, Tom (tojoko)
