Αυτό μου φαίνεται καλύτερο από το Cat-5: http://en.wikipedia.org/wiki/Category_7_cable
"more stringent specifications for crosstalk and system noise ... rated for transmission frequencies of up to 600 MHz"
Δυστυχώς καλά όλα αυτά αλλά όπως σας έχω πει, για τα studio ή τα pc. Για εμάς είναι ήδη πολύ αργά...
Στο σπίτι μας και για την ευκολία μας, θα εξακολουθήσουμε να ψάχνουμε για το καλύτερο ψηφιακό καλώδιο (ελπίζω από τα link να καταλάβατε για ποιούς λόγους ακούγονται οι διαφορές στα ψηφιακά καλώδια ΙC...), το οποίο θέλουμε δεν θέλουμε θα είναι με XLR ακροδέκτες. Βλέπεις ότι παντού μιλάνε για πρωτόκολλο aes ebu... οπότε το spdif και τα απλά καλώδιοβύσματα καληνύχτα σας, τα bnc δύσκολα, τι μένει?... οεο? 8)

This way you can JUMP the receiver of the DAC (that can cause jitter) and feed the 24/192 DAC directly! Very, very sano. No need for esoteric digital cables, gold plated connections etc. Just few cms of RJ45 computer cable will do the job!"

"Interconnection to the Oktal was first a 1m Cat.5 cable, then the 50' (σ.σ.: 15 μέτρα) Cat.5 cable used in my auditioning. The analyzer performed a high-resolution spectral analysis on the Oktal's analog output while it decoded this signal and searched the FFT bins for symmetrical sidebands around the central peak; the result is shown in fig.8. With the short datalink, the weighted sum of the jitter components was a low 261 picoseconds peak-peak. This increased slightly but inconsequentially to 271ps with the very long cable."
The grayed-out trace in fig.8 is a spectrum taken from the analog output of Linn's Sondek CD12, which had one of the lowest levels of word-clock jitter I have ever measured with the Miller Analyzer: 137ps. Note that the expensive player's noise floor is around 3dB lower than the Oktal's, and that the central peak, representing the 11.025kHz tone, is more sharply defined. The rises in noise on either side of the tone with the Oktal suggest the presence of slight low-frequency random-noise jitter.
