Najda volume control is analogue in each channel. The rest I don't know, especially I don't know how DSP is implemented and if individual time delays are possible. But if you are able to physically time align your setup, I think this is very useful.

 
Do not want to derail the thread about the magnificent Paul McGowan, and it is despite that Amir has fucked it up, but I would disagree with you, gordan. About Najda. It is good for them that they went with analog out, if they did but in context of multichannel output it is wasteful and an indication that they have one extra and completely necessary buffer stage. A volume control should be at input but at output, otherwise you would need an active stage to drive the cable after the volume control. A good analog output stage is expensive and to waste it for not used channels is very expensive. So, if they go with analog output stage for each channel then it is a very simple and cheap adjusting a feedback in opamp or in some kind of integrated chip where the functionality has built-in. So, I would vote for no volume controls in DAC outputs, would it be a single channel or multichannel…
