    But the extra connections will only increase the impedance (resistance) by a few tens of milliohms, if that.

I can guarantee that 99% of forum members have amplifiers that rely on voltage dividers to work.
    I dunno; I can only report what I heard. I wanted the attenuators to work, and they did to the extent that they increased the 'usable' range of the volume control, but (for me) with the unwanted side-effect of deadening the sound.

    Maybe, but the degree to which any degradation (by increase in impedance) happens is not the issue. It's still degradation by extra contact connections. If my current quest to find the correct attenuation for my CDP to pre. signal path finds fruit, I shall have that value incorporated into the pre. at the first opportunity.

    And what is it about a single extra contact that causes degredation?

    I agree it is unlikely to be the culprit. But for everyone who says that attenuators worked fine for them there is another who says they flattened the sound. That was certainly my experience when using them with a Croft pre-amp. Baby went out with the bathwater. And yet I have seen other people say they use them with the exact same pre and they do not affect the sound quality. So there must be some other factor at work here.

    They flattened the sound in my system.

    seems to depend on system they are in, reading between lines here. plenty folk like them too;
    and i dont think it fair to pick out rothwells over other makes. they are pretty much the same thing.

    “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.”

    As they say: you can't please all of the people, all of the time. In any business, if you've had positive reviews of a product you sell from over 10,000 satisfied customers, I'd say that there's good cause to rejoice, as you've obviously been doing something right!
