    Squeezbox Duet and Bang&Olufsen 4000, need for attenuation

    Hello all,

    I just recently got myself some B&O 4000 speakers to get rid of my old sony hi-fi.
    The idea, minimal setup, squeezbox and amplified speakers. I use the system mostly at low volumes, and this is where my troubles starts.

    The minimum volume on my Duet is a 1 and still to my taste too high, mostly when I want to read a book and still have some background music.

    I tried some Rothwell in-line attenuators with -12db. They did reduce the hissing noise a bit when no music is playing. But it did not resolve fully my volume issue to a satisfactory level. And the other issue is that now the speakers don't turn off as there must be some noise preventing them to go in stand-by...

    Maybe just to say, I am not an audiophiles expert and not a purist either.

    So I am asking myself what I could do, on the wiki: http://wiki.slimdevices.com/index.ph...rce_line_level
    I found the Goldpoint SA1 (http://www.goldpt.com/sa1.html) that is pasive, and of a minimal design, the price is faar from the minimalistic/simple design.

    I do feel this would solve my problem as the duet output around 4 volt and the bang and olufsen are 0.125 not good at the formula but I recon I would need between 20 or 30 db attenunation... the Goldpoint SA1 allow up to 24 setp of attenuation from 0 to -62db (http://www.goldpt.com/info.html).

    But what about this noise that the speakers don't tun off? what could be done there or would this disapear with more attenuation?

    Also I was thinking the Duet or other squeezbox don't provide connection to ground, could this improve the system?

    About the Rothwells, they do custom orders so you can pick your level of attenuation.

    In the end I went with the Goldpoint SA1.
    No impact on sound quality as far as I can tell, no noise. And finally I am able to fine tune the volume to a very low level for book reading.
    I do have to say the price of the Goldpoint preamp is not cheap. But it is a very high quality product in my opinion so worth the money.
