    I'm all for it Dave - I am just wondering how to implement a digital crossover without going fully active.

    I reckon future DACs will be able to do this in conjunction with a pooter.

    You mean a digital crossover with your RR3s, putting them into bi-amp mode?

    You'd need another stereo amp and a digital crossover like Jim's Behringer, with both amps placed after the digital crossover.

    There are a number of software projects around that provide active cross-overing.

    That's cool. 

    I just did some Googling and came up with this set of instructions on how to do it on the Mac.

    That looks thorough. You have to use two DACs or have some way of splitting the output into 2 or 3 sections.  I didn't read the article completely.

    I must admit that I didn't read it in depth, being a crossover-less kinda guy ;-)

    Indeed.

    That's basically the idea - I don't see why the pooter can't do it digitally. The drawback - as Jim has observed - is the (potential) need for two DACs, or at least a specially designed DAC with two or three outputs which can be controlled from it's host pooter (wouldn't be much good for CD players though). Multiple power amps are a given.

    Just musing, you know! (without any technical knowledge at all...)
