    I find the latest version with the asynchronous TE8802 chip to sound significant better than the original version. I got mine with both TCXO upgrades. Better clocks usually mean better sound... My sistem is sounding better than ever!!

    How do you guys feel about I2S vs S/PDIF when connecting the DI to your DACs? What kind of sonic improvements if any?   What cable are you using?   I received two I2S kits from Kingwa and intend to try it connecting my (new TE8802) DI-DSP to my NFB-8 DAC. I'm just wondering what kind of...

    Quote:   No problems here. I can output 24/192 to an Audio-gd NFB-8 DAC, and a NFB-12.1 Headphone amp/DAC.

    Quote: No replacement is needed. You have to solder the 2 resistors (3 ohms and 5.1 ohms) in parallel with that 3 ohm resistors shown in the Agd diagram.   I got a 3.32 ohms resistor instead of 3 ohms, but it works.The 5.1 ohms resistor is grey, mostly hidden by the 3.32 ohms blue...

    I have to conduct more critical listening to be more conclusive. These are only initial impressions... And I'm letting the device burn in a bit. But my feeling is that the USB cable appears invisible, without any signature. Not like the original DI. Regarding the harshness, I only noticed this...

    Yes, it's the 88 ohms cable, which is within USB 2.0 specification. It is a twisted pair with a braided shield (all 3 Canare are). The specification asks for twisted pairs for the data pair. I connect the shield at both ends. The connectors have to be adapted a bit for all that shield... I'll...

    If you're interested, I should be able to build you a USB cable using the L-2T2S. Send me a private message and we can discuss.

    This morning I was able to give a serious audition to all the USB cables I've being building for the past few weeks. And also evaluate the effects of the Olimex isolator in my main system.   For your reference, the system consists of an Apple MBP 15" (latest model - also used for work) -> DI...

    Some pics to illustrate my recent posts:   Canare DA202 USB cable with Olimex isolator fed by Agd DI-PSU.       DI hanging on the back... Not very elegant, but very effective!

    I've been experimenting with USB cable design and it seams that I might have beaten Monoprice after all. I still need some more listening to be conclusive.   After building cast cables using Canare DA202. I decided to try them as USB as well. One needs 2 runs since they are twisted pairs...

    Agreed! An adapter instead of a cable for the spdif connection is the way to go. I got a BNC to BNC from Markertek (US) that works quite well. I do have to suspend my DI to reduce stress. It's an odd instalation, but it does work very well. Now my struggle is to build a USB cable that sounds...

    Thank you for the tips Peete! Indeed, I have an Audio-gd power condition I really like... I few years ago I moved my main system from my leaving room to my basement and lost my dedicated 20 amp outlets... My wife kicked me out once I placed the "fat" Thor's... I still haven't found time to move...

    Yes, the Olimex USB-ISO is quite impressive. I did try feeding it with the DI-PSU, but I only noticed a slight difference, if any. I have to compare a litle further for a final conclusion. What I noticed though is that the Olimex device got quite hot! Not good for component longevity... Not...

    Agreed, not all listening fatigue comes from electronic distortion. It might be a standing wave, or volume, or just a long exposure to complex sounds. Some recordings will also create fatigue due to electronics, acoustic problems, etc... I can't fix those. I still want my system to be...

    I just put the ACR back in the system. I agree with your comments, a bit more clear. Since I've build some new cast cables using Canare DA202, I'm reevaluating some previous observations. But the thing I always try to avoid is listening fatigue. I've been fighting it for the past 15 years... How...

    In my main system, I'm just using a BNC male to male connector between the NFB-8 DAC and DI. Only when I add a player, I use the Belden.

    Thank you for the link!   Not sure if faster hex inverters will be for me. It looks like the sound like fast op-amps: detailed but fatiguing... But I'll give it a try anyway, it's easy enough.   What USB cable are you using? I've tried a few "audiophile" USB cables, and kept going back...

    Quote:   That should be fun!   I wish Audio-gd would pay me to write here... No associations, just a regular customer.   I still think that OTL amplification is the best around if a bit unpractical compared to a good SS design. I'm saving for The Beast from Transcendent.
