Αυτός έκανε τα παρακάτω:
"Take a look at this comparison diagram: on the top is a block diagram of one of the best PCM-based processors in the world. Notice the circuitous path taken by the audio data stream to the output of this converter. Then look at the pure simplicity of the DirectStream. The PCM processor’s tendency to mask music’s subtle details is largely due to its complex needs, and the technical requirements of PCM processors."
"Put DSD into DirectStream, you get DSD. Put PCM (how CD’s are recorded) into DirectStream, you get DSD. DirectStream converts all digital inputs, including PCM, to pure 1-bit DSD, in an elegantly-simple path. In the process, the PCM feed becomes more linear, less edgy, and never-before-heard musical details are released from all digital audio recordings. Billions of CDs and high-resolution downloads worldwide will gain new life, and be saved from obsolescence. There’s a notion floating around high-end audio circles that DSD may be nothing more than a passing fad. In fact, we would suggest the opposite may be true. PCM based music decoders are nearing the end of their lifecycle in favor of a significantly more musical sounding format, DSD."
Και ένα video του Παύλου (Paul Mcgowan απο την PS Audio για όλα τα ωραία του μηχανακίου τούτου...)
Μου άρεσε η φάση:
1. Που λέει ανοικτά ότι του αρέσει πολύ το Mirus
2. Εξηγεί πως το DoP ΔΕΝ ΚΑΝΕΙ ΜΕΤΑΤΡΟΠΗ (το έχουμε αναφέρει πολλάκις και στο όμορφο forum μας)
3. Που βάζει ένα σωρό flames για να ανοίξουν οι ασκοί με τα analogodigitalικά οπαδικά...
4. Που μιλάει για τα ρολόγια, τα ατομικά, τα femto κλπ κλπ...
5. Καραγούσταρα που πραομοίασε το DACίδιον με το Illistrator!!!! Αδερφέεεεεεεε μουυυυυυυ... :flipout:
Σας φιλώ... :grandpa:
