@treynolds155 Hi,You will get even better results if you convert the USB to I2s you can use this or similar:
Ditch your USB cable for Toslink? Might surprise you!
I recently embarked on experiments with an updated USB cable between an Aurender N100h and a Qutest dac. (cables were Pangea, Curious and DH Labs) Bottom line, it most definitely revealed improvements but also exposed some flaws. So I looked into other tweaks to improve the chain...reclockers, decrapifiers and the likes. All these devices designed to fix inherent issues with USB. So I had the "duhhhh" moment and thought instead of fixing it....replace it.
I went out on a limb and got Aurender's UT100, a device which converts the USB output to Toslink (best option as the N100h only has usb out). I connect a modest Audioquest Cinnamon cable to it and I've been testing and burning in this new device and the input on the dac for several days now, Redbook all the way up to 24/192. And I must say I'm impressed, really impressed. I'll summarize my experience by saying it's just as detailed, but with a more relaxed presentation, no digital "grunge". This is the first time I've even considered trying the incisive filters on the Qutest.
I think Toslink is looked down on as a digital interface, but I'm seeing some big advantages to it now.
- You gain 100% isolation, it totally "air gaps" your dac from every form of interference. I've personally experienced some Bermuda Triangle kinda weird issues with USB and there have been lots of posts lately regarding this. Fiber puts an end to that....period!
- The price of admission is downright cheap, most streamers and dacs already have the connections and I don't think you have to pay a lot for a quality fiber cable.
- On some dacs it's generally accepted that the SP/DIF connections sound better than their USB counterparts. I've also read that disconnecting the USB cable from a dac, turns off it's internal clock and associated circuitry, thus less noise internally.....?? I have no clue but what I am warming up to is the idea that I want to stay away from USB. I've had great results with coax too, going back to my Theta and Sony ES days, but Toslink is cheap, allows long cables if needed and does truly isolate the dac.
I'd encourage everyone to just try it, perhaps your equipment will respond favorably like mine did. I'd love to hear other's experiences, especially Node3 owners. I'm planning on getting one for my office rig.

@lordmelton Thanks for the link, I think I'd stumbled on their converters during my research of this. While my Chord dac doesn't support I2s directly, here is a quote from Rob Watts himself. As ALWAYS, the devil is in the details, and the manufacturer's implementation trumps all. "Yes traditional SPDIF receivers are not good at recovering the SPDIF and creating a clock, as they rely on an analogue PLL - and the data itself modulates the clock, so you get signal correlated jitter which is extremely audible. But my SPDIF receiver is all digital, and relies upon the low jitter local clock, and does not create signal correlated jitter. The SPDIF receiver creates I2S data, with zero signal correlated jitter; plus a word clock, exactly as if it was transmitted via a real I2S connection. So who the heck knows? I'd imagine every decent dac has a similar SP/DIF implementation as Chord. What did steer me in my direction was simplicity. One cable, no extra boxes with more power supplies (perhaps even benefitting from LPS). It can get crazy pretty quick, this set up from Audiowise really started to point me to fiber: Audiowise SRC-DX

I have to say that I am skeptical about converting usb to anything else. The USB is still in the system so if it is adding issues, putting another cable and adapter downstream doesn't get rid of hem. You'll get a different sound I guess, but you haven't eliminated the evil that the USB is adding. Now I'll disclose my opinion about USB. USB is not evil. It suffers from attacks by people selling competing technology or cables for competing technology. Jerry |
