Yes, and they are all made by HSBC (a Government owned garage exclusively manned by ex tank mechanics.)

yea i thought there was, it's obviously extremely small yet does the job just fine. i wonder why the likes of the dacmagic, vdac etc cost so much money considering they only contain a few inputs and a tiny dac chip? there must be big money to be made from dacs...

God, if I'm wrong I'll hang my head in shame.
so you weren't sure? i was pretty sure..

Usually is...
Think this one may be headed for a rant about what a rip-off standalone DACs are when an iPod shuffle already has a DAC built-in and costs not very much at all.
Would get the comfy chair and popcorn, but have a bus to catch...

not a rant andrew, i'm just curious..
digital audio data is a numerical representation of the analogue signal, a dac converts the digital data to analogue, i presume therefore that for different dacs to sound, well, different, that they must add some colouration? to give them their "house sound" if you will?

Does beg the question tho...is there such thing as a 'digital' speaker that doesn't require the signal to be converted, and do active speakers also recieve a converted signal or do they have built in DAC's to do that themselves (never tried any so don't have a clue how they work, just that they have their own built in amp and require a power supply)...
mmm, always looking out for innovations...digital speakers...is this a deadend or technically pointless and unecessary idea?!

The DAC chips themselves are unlikely to add coloration, it's the circuitry after them in the chain that may do so.

but i wonder how that could be done? given that the analogue signal is in effect a series of electrical pulses that "once amplified" provides the speakers with the neccesary electrical signal...

Well, since a digital speaker would have to be either on or off (i.e. making one type of sound or making no sound), it wouldn't be particularly musical. It could work as an alarm I suppose.

No, that's the digital signal.

As the professor said a speaker with a digital signal will not work. Active speakers can either have an amp or both DAC and amp in them. But however you do it, you need both if the source is digital.
In the same way all CDPs have a DAC in them as the source is digital.

I'm having a blonde moment (think my life might be one long one actually), could you go remedial for me?

A digital signal is on or off (1s and 0s) and has no power to drive a speaker. An analogue signal is voltage variations (a wave form) which has power to drive a speaker. If you converted the 1s and 0s into power all you would get is on or off, or a noise and silence.
Convert the 1s and 0s, which describe a wave pattern to an analogue signal and you get digital analogue conversion (DAC) for an amp to boost to power the speakers.

Aren't Meridian's speakers considered digital? In any event they have built-in DACs I think.
