Ashley James:I've just seen you comments so will add that jitter is only an issue when you either A to D or D to A and that modern DACs are largely immune to it. In addition to this, Manufacturers Application notes explain various ways of reducing it or removing it. Because ADM9.1s are used in Studios we use a sample rate convertor like Benchmark do to remove it altogether.
Devices like Airport Express, Roku, SB, ATV, PS3 or whatever all receive bit perfect information in the same way and will either work or not. They cannot function less well because the cable isn't right. All you'd get is drop outs or no sound.
CD's are stored differently on a computer to a CD player. A CD player has redundant data, it makes one pass, does the maths and if it doesn't get enough data, it first guesses and if that doesn't work, it mutes until it's collected its thought. It does this quickly so you don't notice.
A computer is different, HDs keep reading until they have all the Data. They load information onto the ram and do a checksum. Once they have all the noughts and ones in the program, they play it perfectly every time. They read CDs as CD players do, but once they have a read, it never alters any more than any other of the many programs you run.
Class D Amps are digital because they switch on and off thousands of times a second to produce the music. They are more efficient but have more distortion and a higher output impedance than Analogue Amplifiers. They are what you find in Telephones, PMPs and car audio where current consumption is an issue. There are some for hi fi and they are better than some analogue amplifiers, but not as good as the best.
I hope this helps and I'm forgiven.

Ashley again you contradict yourself. you have previously stated that all digital sources are the same (a gross and unquantified generalisation) and yet you now are telling us how differently PCs and CDPs operate in providing a digital signal. both are digital sources and yet, as you explain in some detail, both are very different!
not everyone on this forum is so easily blinded by your techno babble and product promotion that they fail to see the flaws in your arguments.
that said i would love to atend an open day to really hear what your products are capable of with any given source (as theyre all the same).
