  1. Per Alex's first post in this thread: "The goal of the unit is to provide full isolation (and very high-quality clocking) for one special "clean" port--to be the port that feeds your Ethernet-attached streamer/renderer/DAC device (be that something like a micro/ultraRendu, Aries, SOtM, Ethernet input DAC, or whatever Ethernet connection is most directly connected to your DAC)." Did this change?
  2. It is my understanding the the optical port is on the "dirty" side of the switch which would basically defeat the whole purpose of using the EtherRegen.
  3. Recently picked up a Klipsch The One ($250 on Amazon) which is the smaller version. My wife had started listening to Josh Groban videos on YouTube using her laptop in our kitchen/den area. As you can image, laptop speakers are horrible so I needed something. If my wife can't just power up her laptop, open up YouTube, select a video and hit play, then this would be a no-go solution. So far, The One had worked well for it's intended purpose. Plus it looks great with the wood veneer finish.
  4. I posted a schematic of my existing home network system that includes fiber optics (see below). My network uses Google Wifi but you can simply replace them with the eero, basically the same same. The opticalModule would replace the existing FMC in my current system. However, if you go with a opticalRendu, no need for a FMC is needed, you go straight from the switch to the opticalRendu.
  5. You can get PC's with a small footprint such as the Intel NUC units. Install Roon core (highly recommended) on it but control it through your iPad, assuming you have a WiFi network. That way your PC can be tucked away and out of sight if you want. Roon can connect to your local music files as well as Tidal & Qobuz. Your local music files can be stored on the PC, an attached hard drive or a NAS unit. As for an amp, yes, you will need an amp. It could be separate power amp, integrated amp or part of your speakers (powered speakers). The signal coming out of most DAC's are low powered and not enough to drive speakers. You also need to decide how to control the volume. Roon might be able to do this ... I don't use Roon to control volume so not familiar with that. Some DAC's have volume control. Or you might need an integrated amp or pre-amp. All that said, there are units that can serve as DAC, pre-amp & amp all rolled together. Lots of options, just depends on what you are looking to do and of course how much you want to spend.
  6. Here is an unmanaged switch that I have been using for some time in my system that supports 802.3x. Diablo Cable - Dual SFP Slot Media Converter with Dual 1000M Ethernet Ports

    In the past, some us here on CA have done this (send $$ to developers like Miska) in appreciation of their continued development, support, contribution and advancement of our hobby. Guessing, PayPal is probably the easiest way to contribute using [email protected] email address. Miska can correct this if needed.
  8. With prior approval from Chris, I would like to share a webinar recording that my company (SimuTech Group) recently did. It is a technical look at the design and engineering considerations for high-speed connectors (USB, RJ45) using engineering simulation software from ANSYS. The simulation software allows you to visualize what is going on (e.g. crosstalk) and how design changes can impact performance (or not). I know there is a lot of discussion on CA on this topic so thought it was appropriate to share and hopefully provide some insight to the design and engineering world. https://vimeo.com/simutech/high-speed-connector-design Aspects of signal integrity simulation for connectors are discussed, including topics such as optimizing PCB and connector assemblies, building high speed channel models, tuning impedance, and more. Example simulations (e.g. animations) that put the theory to practice and highlight some of the features commonly used by connector designers. Overall, this is a 46 minute video including about a 6 minute company overview (feel free to skip) that I do in setting up my engineer, an ex-Molex employee (Signal Integrity Project Engineer) who was heavily involved with the design and modeling of Ethernet magnetic jack chokes, transformers, and PCBs – each optimized for high voltage withstand and signal integrity for 1Gb and 10Gb Ethernet applications.
  9. According to GitHub which has something to do with DSD for the Linux driver (ALSA), support for the Amamero Combo384 was added on November 30, 2016. However, you need to make sure that the firmware on the Amamero Combo384 is the latest version (or at least new enough to support DSD).

  11. Based on Miska's recommendation at the time (several years ago), I was using the Cubox-i4Pro unit as a NAA only. Some of reasons to go with something like a Cubox-i are for noise reduction - no fan, no HDD, low power requirement (5V), ethernet connection (isolation from noisy main computer), ability to use LPS - making for a very low noise platform feeding your DAC. Whereas with a Mac Mini, you usually have a fan, HDD and a switching power supply ... there are means around these things but it costs $$$ in addition to the cost of the Mac Mini. Please note that if you decide to go with the Cubox-i, Miska's canned NAA image for Cubox-i does not allow you to modify anything (e.g. install TV apps). In fact, you cannot even log into the Cubox-i at all. So, if you want to add apps, etc., you will mostly like need to install Linux, etc.

    If you have 4 cores, why not use Pipeline? This will spread out load equally across all 4 cores. As for the pop, this is a common issue when using Linux with many DACs. Sent from my iPad using Computer Audiophile
  13. Curious if you could use this as TV soundbar via the analog inputs. Too bad it does not have a TOSLINK input. In my daughter's playroom/family room, I have a separate low-end stereo system and a TV. If the Three could pull double duty, that would allow me to pull out the stereo system plus gain better TV sound.
  14. There is a setting that controls this. If you leave it at the default setting (throttled) then it can take a long time. You can change the setting at Settings > Library > Background Audio Analysis Speed My computer has 4 cores which what my setting is. It still takes time but probably hours and not days.
