If redbook manufacture is supposed to commence play at exactly 2.00 seconds from the true zero pressed on the cd aren't we discussing data here.Programs like the forgotten Perfect Rip take this very seriously,correcting for sub-channel data in the process etc.Bit correction for offsets is what it is all about.I have discovered that Nero CD Speed Tool does report offsets correctly,just giving a total figure.Perfect Rip confirms Nero and this means that the Accurate Rip database is incorrect.All offsets given there are +30 samples out for every drive listed.I no longer get silly anamolies with ripping,they are perfect every time.I might add that voltage brown-outs and spikes badly effect ripping also.You reap what you sow.
Does the quality of a digital signal matter?
I recently heard a demonstration where a CD player was played with and without being supported with three Nordost Sort Kones. The difference was audible to me, but did not blow me away.
I was discussing the Sort Kones with a friend of mine that is an electrical engineer and also a musical audio guy. It was his opinion that these items could certain make an improvement in an analogue signal, but shouldn't do anything for a digital signal. He said that as long as the component receiving the digital signal can recognize a 1 or 0 then the signal is successful. It's a pass/fail situation and doesn't rely on levels of quality.
An example that he gave me was that we think nothing of using a cheap CDRW drive to duplicate a CD with no worry about the quality being reduced. If the signal isn't read in full an error is reported so we know that the entire signal has been sent.
I believe he said that it's possible to show that a more expensive digital cable is better than another, but the end product doesn't change.
There was a test done with HDMI cables that tested cables of different prices. The only difference in picture quality was noted when a cable was defective and there was an obvious problem on the display.
I realize that the most use analogue signals, but for those of us that use a receiver for our D/A, does the CD players quality matter? Any thoughts?
