earlier Musical Fideltiy V-LInk to new V-Linkll


Anybody know of any differences between the first generation V-Link (now on clearance for $99) or the newer V-Link ll for $189?
I'm talking about the coax/toslink out versions...I want to toslink out..
Thanks!

I really don't know if anyone needs or cares, but I bought a similar product on fleebay from a seller called Gigawork, works quite well and sounds very good. $98.
It is not always listed, but pops up on occasion.

The Lars Audio USB 01 24/192 converter is a must-have component for your computer-based music system.

The USB 01 24/192 converts a computer-derived USB input of up to 24 bits and 192kHz to SPDIF and outputs the signal on a 75 ohm RCA or the optical output.
It immensely improves the sound of your 16-bit 44.1 kHz music files as well!

• Asynchronously Converts USB computer-sourced files to SPDIF or toslink output
• Cmedia new CM6610 true USB 2.0 high speed chips
• Accepts high-resolution audio files with data rates up to 24 bits and 192KHz•
• Low-jitter clock recovery features reference crystal oscillator
• Self-powered via Asynchronous USB input benefiting from LC filters and low-noise local regulation and it can be upgraded via a external power supply.
• Galvanic isolation between computer and audio system prevents high-frequency noise from polluting signals

Compatible with Windows XP, Vista and Windows 7 only.
Hi DTC,
Yes, Gigawork does take some of the best from the DIY community and further develops it. I belong to a couple of those forums also, thats how I found it and yes again, it does have galvanic isolation on the USB as well as a seperate power input for 5v to 7v. It outputs at all except 24/88.1 and 24/176.2. I had several of those files and had to convert them. Decided to go to 24/44.1. They still sound excellent.
Ebay has a note that Gigawork is on vacation. I hope this info helps someone. It really does do a great job.
This is a copy & paste from My Ebay, I have it saved:

•Accepts data up to 24 bit/192 kHz
•USB powered
•Asynchronous USB transfer, re-clocking with a fixed low jitter crystal clock
•Galvanic isolation between USB and the analog circuits, which means no noise from the computer will be transferred to your amplifier
•Super low noise power supply with multi-stage regulation and filtering
•For low out-of-band noise we use low order modulator
•For a more "analog" behavior (no pre-ringing) we use a digital filter with minimum phase
•The analog output stage is a high performance stage with high drive capability
Hi Dtc,
I haven't opened it up, but I do have photo's saved. The ads clearly say Galvanic isolation all over the place. They don't tell you that it won't play 24/88 or 24/176, I found that on my own and upon emailing they confirmed. They use the Cmedia new CM6610 true USB 2.0 high speed chips. I know that Schiit uses a newer version of this on the Bifrost and there have been lots of post that there are issues playing the same files. My understanding though is that this is the sole difference between the Schiit chip(cm6631?) and this, so my guess is that this chip is the cuprit of why it will not pass these files.
My DAC does have a USB in using the Tenor 7022 which is 24/96 and in this case is not Asynchronous. The Lars Converter, clearly improved over the stock usb in with a touch of focus to instrument placement, It clearly improved just a touch of tightness in the bass and it clearly improved high end extension. I first used this powered by my USB only, it was quiet and smooth, before it was ever completely burned in, I found a 6v 1 amp walwart that I had previously added a cap to and replaced the cord on both ends with heavier guage, surprisingly nice little power supply and I put it on and never really compared or worried about galvanic isolation again.
Hi Tom, I opened the box, metered the USB connection to the board, went to the ground on the spdif coax... Nothin... Just to make sure I used pin 4, I went to the opposite side pin on the usb, hit the ground on the spdif... nothin. Put my trusty Fluke on the coax ground trace to the board, and the outside ground... its squeals. Sure seems to be Galvanic isolation to me.
Sorry I didn't answer your question Tom about the HiFace, sorry, I haven't tried it. If your ever in St. Louis, let me know, I'll give you my info, you'd be welcome to stop by and check it out. It clearly betters my USB in on the DAC. By the way, took about 40 hours of burn in. I was actually surpised that I would tell much on a converter, but there was definately an improvement...
Hope some of you others on the thread get something from all of this, I had no intent to steal the thread. Sorry
Tim
Hello all, just an update on the Lars Audio that I posted about... I had sent an email to Gigawork.. they replied that indeed the sound of their converter was more than they hoped for, but they didn't count on driver issues.. it seems that Kernel streaming and other formats won't work with the Cmedia 6610 and Cmedia is not producing any drivers. Windows has a couple drivers that work fine for Wasapi, but won't support ANY of the others.... Of course, I didn't know that and am using Wasapi...
Gigawork pulled this converter until they have a solution... if you email them directly, they will still sell one, but be aware of the situation.
I hope this helps, Tim
Well they tell me they pulled it, but here it is...
