First off, let me apologise cos I mispoke earlier, you can indeed resolve signal below the noise floor but not below the noise density floor in both analogue and digital, so my apologies for mixing up the two terms in my original post.> > The point is that while in digital resolution and possible noise floor are both determined by the bit rate. This is obviously not the case when it comes to a cutting head in analog, noise floor and resolution are not linked.
That's not strictly correct, the word length does not necessarily determine the resolution, an extreme example being DSD with a word length of 1 bit but a dynamic range (up to 20Hz) of > 120dB. Furthermore, as stated above you can resolve signal below the quantisation noise floor up until you hit the noise density floor at the cost of much higher distortion, there are ways round this but that's a separate discussion.
> > good cutting head has an upper frequency limit of 50kHz and thus can reproduce detail above its noise floor that 16/44.1 digital can not match. This can heard by how accurately cymbals are reproducedYou are confusing upper frequency cutoff with the noise floor.
