Quanto Jitter è discernibile?

Good quality Interconnects (need not be high priced) are important since they deal with low amplitude signals. The rest is up to you on how much you want to lighten your wallet.

Cables cannot introduce "new" jitter since it is only a medium/channel. But a bad channel/cable (a really bad one) can worsen the "pre-existing" jitter.

But is jitter in digital audio really the demon what it is made out to be? IMHO it is more over-hyped than the NASA moon mission!!!

It has been proven by innumerable measurement and listening tests by audio engineering experts and artists that jitter below 250 nS is undetectable by humans and you really need to have a pathetic cable or system to cause that much jitter. Any decent and modern design will conform to less than 1nS jitter and you need to have really badly manufactured cable to worsen it to 250nS or above.

Quoting a few studies (Highly recommended reading for the Jitter-Demon make-believe brigade!)

Theoretical & Audible Effects of Jitter on Digital Audio Quality by Benjamin & Gannon.
105th AES Convention, 1998
Jitter added to digital signal between transport and DAC with a hardware device.
Conclusions: Uncorrelated jitter inaudible below 10nS rms on pure tones, Uncorrelated jitter inaudible below 20nS rms on music signal

Jitter simulated in the digital domain.
Conclusions: Uncorrelated jitter inaudible below 250nS on music signal.
