CECAA850 Posted April 16, 2021 Share Posted April 16, 2021 Got it. I use 2 optical inputs on my Denafrips. One from my laptop (HDMI to extractor) and one from my Arylic streamer. I can't imagine it sounding any better. 1 Quote Link to comment Share on other sites More sharing options...

That is why I asked @jwc this 2 hours ago, rplace said: But the constraint is the source of the noise (the PC) has to remain? I don't get why you would be looking for improvements and not willing to explore all options. 1 hour ago, Shakeydeal said: something like a Node 2i, or if more ambitious, something from Lumin or Innuous Absolutely an option. However, I am constantly wondering why there is so much love for the Node 2i only to turn around and feed a DAC with it? There are 100 or more ways to skin this cat 50+ of them probably very good solutions. I'd guess most don't fully understand the technology involved and with all the good press and an attractive price point the Node 2 just "works". I fully get plug and play and ease of use. Easier to spend $500 on something that is plug and play than learn something new, source a few bits and spend 15 minutes putting them together. The constraints of PC and 100% USB and no RPi makes me think the mind is made up that there are improvements to be had. Best to pick a few items within the allotted budget and try them and make up ones own mind. If you hear a difference, maybe even an improvement, in your own room with your own equipment then you know. That difference/improvement may only be in your mind, but it does not make it any less real...right? It a hobby and we all love chasing that next incremental "improvement". Its literally what we all do or we would not be here. I've probably spend $2,500 alone on various 6SN7 tubes. No doubt the older, rarer and more expensive for the most part were better...they had to be, right? Just my opinion, so not worth very much, but I think the less you understand the technology the more likely you are to believe there are hidden secrets that can be unlocked. The audio industry has always needed believers not skeptics in order to perpetuate itself. Keep moving like a shark or you die. Many parallels to other things that require belief over proof.

Chris A Posted April 16, 2021 Share Posted April 16, 2021 If your DAC has a local buffer on the USB input channel, then I'm not sure that your remaining issue is the USB connection, but perhaps the analog transfer function out of the DAC. There are USB to AES3 and I2S converters that have their own clocks internally and use those clocks to get rid of USB bus jitter. I'd look for something in that area (if it were me). I know you seem really invested in the USB bus only, JC, but the other approaches will provide equal or better results. About two years ago, I was looking for a USB (from a laptop) to AES/EBU converter with an internal clock. I found some, but beware: the device drivers to recognize these converters on a USB bus weren't up to snuff (mainland China products).

seti Posted April 16, 2021 Share Posted April 16, 2021 I love my music server. The MacMini actually has a optical audio connection so I got toslink from my EAD DAC to music server. Never used a fancy cable it sounds better than I though possible for a music server. I also use it for Tidal.... Quote Link to comment Share on other sites More sharing options...

The buffer will let the music play and the offending noise from USB can't be there any more. Quote Link to comment Share on other sites More sharing options...

Let me first throw out there.....Yes I get it if you think the data connection is just "1" and "0" s. I don't really need to hear this argument again as there are certain individuals who refuse to listen. If that is your opinion.....so be it. I'd like to entertain some reasonable investment into this from those that have experience. No I'm not talking about a $1000 USB cable. I'm not doing that. I am interested in purchasing some items to possibly improve the results from cables to other inserted gadgetry in the connection line. Unless you have lots of transmission errors, or a grounding problem It is a stream of 1 & 0 framed with timing bits and error correction CRC ARQ It's a real data protocol that includes error correction. Other than a shielded cable, you are pissing money away. $20 solution for a good shielded cable. As to which chip set the DAC uses, and how it handles internal buffering, errors, and A to D conversion these are all design considerations by the Engineers, with cost and performance trade offs. A bake off, where you bench test DACs with frequency sweeps, and run test patterns, aka Lazy Dog, and count the errors. Is probably the only way to define any differences, a suck implementation may have audible problems. Frequently, better designs are the ones that handle errors and problems better or gracefully. 1 Quote Link to comment Share on other sites More sharing options...

But the constraint is the source of the noise (the PC) has to remain? Furthermore, a Rpi solution like allo digione or hifiberry digi+ pro is not an option because your not "doing the whole raspberry thing". If so have you considered a DDC from Denafrips to sit between your PC and DAC? https://www.denafrips.com/ddc If I'm wrong above, what are you trying to accomplish over your current configuration? I'm assuming USB out from the computer, please correct me if I'm wrong. What would be the input to the DAC SPDIF/I2S/AESEBU/OPT? If the PC is creating noise that is transmitted to the DAC via a cable the best fix is to use an optical cable Get a USB to toslink converter and use it between devices Most DACS have an optical in port. Also possible the PC is putting noise into the ground a good power supply should filter it out, along with good grounding. Quote Link to comment Share on other sites More sharing options...

This is the type of stuff I wanna hear. By the way....I'm not hearing noise or noticing any jitter.... Even If I could.. lol.

Jitter would be caused by a defective timing implementation on the transmitter, or receiver or in the case of a noisy cable; lost or garbled bits causing the clocks to lose sinc Optical cables that are inferior or defective can cause lots of problems, better to use glass carefully. 1 Quote Link to comment Share on other sites More sharing options...

To Ubuntu Linux (Windows is limiting USB output specs) check out this card https://sotm-usa.com/collections/accessories/products/tx-usbexp-usb-3-0-interface-card I've had almost zero problems with Linux Mint, and not had to install separate drivers. USB3 support is built into the newest distros, and Mint is based off of Ubuntu. Far, far less overhead than running MS Windows. I use the MATE version of Mint, which is a clean install that would look a lot like Win 7. Navigation is easy. Boot a live version from usb and check it out. All my interfaces use USB2, and ca easily handle multiple outputs at 192K. https://linuxmint.com/ Quote Link to comment Share on other sites More sharing options...

I've yet to hear of anyone here that uses some "contraption" in the USB line to make "audiophile changes". Short version Buy a $20 or less shielded cable with USB, the rest is just snake oil. Plug all of your devices into the same power strip, preferably that has some filters built it and ground loops should not be an issue. Grounding my home like a commercial radio tower did more to improve my TV picture than you would expect It already rocked. 4 grounding rods, 8ft around the house, tied together in a ring, all pluming, cable, and power connected into the ring. Added a whole house surge suppressor in the circuit breaker box. This was done as part of putting a TV antennae and separate FM antenna on the roof and ditching satellite and cable for steaming and broadcast.

Off my topic.... but What device do you recommend to stream Youtube videos, Youtube music or if I invest in a Tidal account for videos later? Sorry I won't be much help there as I don't subscribe to any streaming services nor do I use YouTube. Archaic, I know. After 30 years in the software industry I'm more Ted Kaczynski than Amazon Prime, as I value my privacy. That said, I'm very happy with my Nvidia Shield Pro. I only use it for PLEX but would find it hard to believe there is something better/easier for anything you wanted to stream...I'm sure there are cheaper options. If you can't identify an issue (grounding, noise, isolation, etc. they should be obvious) but think/wonder if it could sound better with something inline between source and DAC why not just pick a few you believe the reviews/hype on and try them? return or resell as needed to scratch the next itch. Its what most of us do with most A/V choices. Most people when asked by someone else what XXX should I buy. Will just tell you what they have and why they love it and why they made the choice (correctly of course) they did. They have done their own reading, investigating, research. They have arrived at that point with their own biases and external influences. There is a reason they already have it. I can't tell you how many times I've asked about XYZ, been told to look at ABC or DEF but still bought XYZ. The one thing I did not do that with is my most recent DAC. I was hell bent on a Mytek Brooklyn DAC +. Months of reading, searching, posting on forums. Eventually I bought something totally different, a R2R NOS DAC, based on numerous comments on how analog they sound. Glad I did. Good luck, let us know where you land and what you hear...or didn't hear. Quote Link to comment Share on other sites More sharing options...
