aint superior cd transport serves to supply superior data steam, 101% accurate?

If that is the case, then there is no denying,cd transport STREAM data with little correction from the onboard controller. A computer source (and future source that doesnt require a computer, i know they exists, but im unaware of them) is 102% accurate reading to that nano compared to micron of cd track since the data from the cd is read thru various ECC CRC etc..and to the matter of RF interference in cd transport, why is it a main concern when the data readout is digital? Microphonics from ceramic caps, what ppl shud be worried are the true EMI from the cd motor.

Or maybe i misunderstood, but from the DIY thingie on this thread, it seems like the transport serves data to external USB?

So what is a cd transport then?

beats me why you would want to use a 24V tranny at phreaking 75VA for the whole thing..its just big..big..big..big..heavy n expensive.

Not to mention it would make ur regulator perform worse since more drop-off voltage need to be shed by the regulator=more heat=more noise=less regulation..and not to mention the itsy-bitsy heatsink mount?

Whats the peter daniel regulated PS? macam interesting biggrin.gif

24V centre-tap, two diode meaning full-wave rectification with no bridge since centre-tapped. Output unreg unload is around 34V, drop out to 8 (26V drop off by reg) and small filter values, shuld haf bad ripple and extremely hot thermal situation.
