Teradak Teralink-X2 released 19.1.10 - Page 4

post #46 of 642

Hi,

I've been testing the beta ASIO driver. It works on XP SP3 32 bit but apparently not on Win 7 (neither 32 bit or x64 ).

EDIT 22-02-10 New driver for Win 7 out.....

If you want to try it, PM me, but please agree not to release it to the public and note you use it 'at your own risk'

It is a very simple driver. It automatically selects the sample rate and only allows control over bit depth and buffer length. Plus there is an auto buffer setting.

To me, it sounds the same, perhaps even a little better, than the Ploytec driver, so the X2 is a keeper for me now.

I've finished a y2 dac and connected them through the iis bus. The dac has been burning in for about 6 hours and sounds very good indeed, even running everything from the usb power.



Cheers,

Tom

Hi guys,

Well, I have to say that my less-than-wonderful first impression of this was quite wrong. The I2S output into a y2 sounds pretty amazing tbh. And the dac isn't fully burned in yet either....

WAV 44.1 and 96 khz files - Foobar - 'beta' asio driver - X2 - iis - y2 DAC (with ad8656 and Blackgate NX 220uF) - cryo-cable HD650.

I also tried a Mini3 to give more juice but surprisingly it didn't sound any better, perhaps even a little loss of detail for a bit of a better bass hit. BTW, this is designed to be a laptop solution so I'm not willing to try a desktop amp.

Anyway, I can definitely recommend this combination. I'm really enjoying this ! I'd love to be able to fit them both in a small box.

Sorry to hear that. Are you using 32 or 64 bit ?

The chameleon uses the same USB receiver, and same clocks. It is powered from the main psu of the dac, an outboard DC30W in this case. There is also a Wolfson WM8805 on this board, I thought that it was only used for the SPDIF input though, perhaps it's somehow tied to the Tenor. I get an exact name of the product as well, in the description I see Teradak 96khz usb interface, when selecting the output device from foobar.

Shahrose is also using Windows 7 but it seems he still needs a dedicated USB ASIO (or wasapi...?) driver to get a tight bass response, so I'm not sure it is just XP.

I actually didn't notice the bass - a bit warmer perhaps - to me the sq just didn't sound right - like the effects of jitter.

I heard from Teradak. They have a driver with ASIO and AC3 already written but it isn't ready for public release yet - it's still being tested.

So now I'm very hopeful !

I can't say I love the Ploytec driver cos it seems it won't force 16 bit and I can only get 24 bit. So I guess it pads the word length...maybe dithering is necessary ? Am I missing something ?

Thanks for the reply - it looks like it is the same but I still can't get ks to work - maybe that's an XP thing. Thankfully the asio driver works very well with XP and I'm very pleased with the quality.

Actually, there is almost too much precision with the details and this combined with the slightly fuzzy edge usb power gives can become a little tiring. The sound improves a little running off the laptop battery so I expect there is more to get out of this combo with some decent power.

That's a real shame. It explains why they won't release it.

Hi,

There's a new driver out - interface looks different but functionally it is the same. If anyone wants to try, PM me, but sorry no gmail addresses - they block my email attachments....

It works with XP SP3 and installs as Tenor ASIO driver (2 in 2 out), and the control panel says it is GFEC Tenor ASIO. To me, it sounds the same as the previous driver, which is excellent !

If it doesn't work, please post why with the error message cos this'll help Teradak.

Cheers

if they ever do KS on XP, I'll bite.
post #56 of 642
still no KS on XP w/these drivers? C-Media CM-108 | Catalog - X-DRIVERS.COM

there's 3 different versions compatible w/ XP..

it's kinda strange that ASIO4ALL works but not KS...OTOH, C-Media are known to resample and cheat all over the place in their drivers...like the CMI8738/68 stating that they output 24bit, when they're actually sending 14.

This device uses a Tenor chip, not c-media. I was told it has a buffer ic too so that's why ks won't work, but then some ppl have got it working. I can't and I've tried just about everything.

However, I don't care because the asio driver is excellent - it doesn't seem to colour the sound at all and the definition is faultless really. However, this is through the iis bus not spdif. I think iis seems to be better then spdif.

I've also mainly used this with the y2 dac. I did some brief listening comparisons to other low-jitter spdif sources that also have either asio or ks, and it sounded pretty much the same tbh. All good !

I really like the x2 now and the combo with y2 is really growing on me. I wonder if that is because it is now fully burned in.....

I sure as hell can see a CMI chip on these pics: USB to Spdif Toslink and I2S Converter for DAC - eBay

ok, great! too bad I need KS on XP...it's good that it works on W7, though(mostly because it's got a WASAPI>KS wrapper I think?)

I can't really justify the musiland high cost...especially considering that my DAC runs the DIR9001 chip, that happens to do "50ps clock recovery".

yep, and I can see them too....but that's the x we are looking at not the x2....x2 supports 96/24....look at the start of this thread for some good pics of the x2, and here is the seller's ad.

ah, you got me! but maybe I could get KS on XP w/ the other one....time to dig around.
