V-LINK

NEW! V LINK 24 BIT 96 kHz ASYCHRONOUS USB TO S/PDIF CONVERTER WITH COAX AND OPTICAL OUTPUT

Design Background

More people are storing their cherished music collections on computer. This exciting consumer led revolution gives new and exciting possibilities for audiophiles. However, the standard USB output from laptops has been a serious limitation on ultimate quality.

Standard computer USB outputs are synchronous. This means that the computer will determine its output data rate at its whim. From an audiophile’s perspective this is a disaster. The data rate might be 14 BIT 32 kHz or it might be at a higher data rate. It just depends on…what the computer decides to do.

The solution to this problem is asynchrony. Simply put the receiving device instructs the computer to give it data (via its USB output) at whatever rate it has been stored on the computer disc. This is a big change. Now an audiophile can be confident that the data received from his computer is genuinely high quality and unfailingly consistent. Perfect!

V-Link

The V-Link is 24 BIT 96 kHz asynchronous USB to S/PDIF converter. It is an exclusive in-house, Musical Fidelity development. The V-Link offers perfect performance from USB. Jitter is eliminated. Data transfer is perfect. It really, really does the job.

There are other products on the market which have similar functionality but, unless you spend big money on Ayre or other similar products, they do not work consistently, reliably or in some cases properly.

The V-Link has been designed from the ground up to offer perfect and consistent performance. It will work with a huge range of computers and operating systems. Extreme attention has been paid to all the detailed programming to ensure rock solid consistency. The low jitter power supply feeds an ultra high precision clock which is positioned almost on top of (in PCB terms at least) the V-Link’s vital components. This achieves extremely short tracks and ultra accurate clocking.

Our selected I2 Bus to S/PDIF converter ensures jitter free precision conversion.

The V-Link has Musical Fidelity’s unique proprietary asynchronous digital control system feedback technology software. When added to all the other elements, it produces virtual perfection. The V-Link (24 bit 96 kHz) produces performance equal to the most expensive and the most exotic on the market. It’s true!

Zero Jitter

The V-Link has zero jitter. See Hi-Fi News measurements below.

…”Moreover, it offers completely jitter-free conversion from one interface to the other, as the graph above shows. (Ignore the extremely low-level peaks in the spectrum: they are the residual components of the J-test signal used for my measurement. PM)”…

Optical Output

Interfacing computers to audio systems dramatically reduces the audio system’s performance. This is because computers have large amounts of digital noise on their earths. This seriously reduces audio performance. The V-Link’s optical output eliminates it entirely.

The V-Link’s optical output gives audiophile performance from computers.

Musical Fidelity’s V-series competitive pricing

Musical Fidelity’s V-series offers state of the art performance for a low price. It is done by solid commercial principles and state of the art circuit/PCB design. The V-series has no extraneous anything. It is state of the art circuitry laid out to perfection with no trimmings, extraneous trouser stuffing braggadocio, packaged in a simple low cost housing made in large numbers. We are determined to give state of the art performance at an every day price.

V-Link Asynchronous USB to S/PDIF converter (MSRP $169)

Musical Fidelity's new V-Link asynchronous USB to S/PDIF converter is the newest product in the V Series lineup. I've long been a fan of MF's small size, small price, large performance products and the V-Link is no exception. In fact it's my favorite small component Musical Fidelity has ever made. The V-Link is designed to connect a computer with an available USB port to a digital to analog converter with an available electrical Coaxial S/PDIF or optical TosLink input. The unit is then powered by the computer's USB interface. There are other products on the market that transfer music from a USB port to an S/PDIF port but the pool of devices that use asynchronous USB transfer mode, support up through 24 bit / 96 kHz high resolution music, don't require additional software installation, and cost as little as $169 is currently very small.

The V-Link asynchronous design is based on the TAS1020B USB controller. This in-house, ground-up converter design and specific async USB implementation are exclusive to Musical Fidelity. The V-Link was designed with a high precision clock that sits nearly on top of the critical internal components. Two fixed oscillators, one for rates based on 44.1 kHz and the other for rates based on 48 kHz is also the hallmark of a smart design. MF set its sights on designing this converter "right" and hit its target dead center. The V-Link requires absolutely no manual software or device driver installation. This is a big deal. No matter how often manufacturers suggest that software installation isn't an issue, they never seem to provide evidence supporting that claim. A few minutes spent browsing the Computer Audiophile forum should provide enough information to the contrary. Every audio device I know of that requires software installation to function has had issues with that software. Period. I'll even provide evidence so readers can check for themselves. Simply browse the websites of any manufacturer that offers a product requiring software/device drivers. Look for the software download section or for information about obtaining this software. Take note of how many updates there have been to each software package. There is a reason for new software versions beyond 1.0. If something isn't broke don't fix it. If something is broke …

In previous product reviews and forum comments I've discussed the importance of galvanic isolation[1] between the computer and audio system. Without this isolation audio systems are prone to significant amounts of electrical garbage flowing from a commodity powered computer. Galvanic isolation is not a 100% must have feature of a converter, but purchasing a unit without this may be problematic in some systems. The new V-Link is somewhat "ambidextrous" when it comes to isolation from a computer. The electrical Coaxial S/PDIF output is not isolated and the optical TosLink S/PDIF output is isolated by the nature of the optical connection. Like the Creepy Kinglink says, "Have it your way." Isolated or not each user can identify the connection type that works best in his system.

Ναι αλλά μόνο μέχρι 24/96. Το hiFace (ο βασικός ανταγωνιστής του αν σκεφτούμε ότι και τα δύο κινούνται στο 100άρικο) φτάνει τα 192 αν δεν κάνω λάθος.

Βέβαια το hiFace δεν ξέρω αν είναι πραγματικά ασύγχρονο.

Το HiFace δεν ειναι αλλα το Evo ειναι ασύγχρονο.

Κάνει όμως 350.

To ότι το vlink δε παίρνει πάνω από 24/96, μήπως οφείλεται στο ότι δε χρησιμοποιεί drivers? Θυμίζω αυτά που είχε πεί ο συνφουρμίτης tonal:
Μη ξεχνάμε πως όλα τα ολοκληρωμένα που παίζουν χωρίς drivers είναι usb 1.1 και επομένως υπόκεινται στους περιορισμούς που επιβάλλουν οι προδιαγραφές σε αυτή τη κατηγορία συσκευών (usb audio class devices).
Ακόμα και οι συσκευές που αναπαράγουν 24/192 το καταφέρνουν μέχρι τώρα μόνο με drivers και σε περίπτωση που είναι συνδεδεμένες σε θύρα 1.1 δεν υποστηρίζουν πάνω από κάποια ανάλυση/ρυθμό. Ενδεχομένως υπάρχει κάποιο πρόβλημα, μάλλον της Microsoft, σχετικά με τους ενσωματωμένους drivers των Windows για την usb 2.0.

Αυτην την εντυπωση ειχα και εγω (και θα εβαζα και στοιχημα) μεχρι που μου το ειπε ο ιδιος ο αντιπροσωπος οτι δεν ισχυει και οτι το "μικρο" δεν ειναι ασυγχρονο.
Τωρα τι να πω...

έχει και κάτι κινέζικα στο ebay... σαν φθηνή λύση αξίζουν;;

Μόνο αν οι απαιτήσεις σου είναι πολύ μικρές. Αγόρασα κι εγώ ένα αλλά το παράτησα μετά από μιά βδομάδα. Aν βέβαια θέλεις να δώσεις πολύ λίγα χρήματα μπορώ να σου το αφήσω για 15 ευρώ...

Έτσι για τι γαμώτο έστειλα ένα email στον Ιταλό ρωτώντας τον για το αν είναι ήόχι ασύγχρονο και του διευκρίνιζα ότι του μιλάω για το μικρό και όχι για το evo.
Η ερώτηση μου: I would like to ask you if the hiFace (not the hiFace evo), does works in asynchronous mode?
Και η απάντηση του :
Hello Kostas,

yes, hiFace works in asynchronous mode.

απιστε θωμα kosti
άπιστος εξακολουθώ να είμαι για το hiface διότι σκέφτομαι ότι μπορεί αγοράζοντας το να πετύχω αυτό με το βλαμένο ταλαντωτή, όπως την πάτησες εσύ. Εκτός αν δέχεσαι να σου το στείλω (αν το πάρω) για μια ακτινογραφία. Αξονική καλύτερα γιατρέ μου.........:ernaehrung004:
