    Another option I have not seen mentioned is to add a fiber optic card to your music server. I have an Intel card & SFP installed in my Linux-based server. I don't recall the exact card or pricing (mod done several years ago) but bought everything off eBay for not a lot of $$. (As a side note, the drivers for the Intel card are directly supported and update by Linux - Ubuntu). So my current system has fiber optics cable coming out of my music server to a switch similar to what is included in the kit. From the switch I run a copper Ethernet cable to my mRendu. No idea on how my configuration compares to this new offering. My guess is that is not as good but ... I would like to get the new opticalRendu if I can handle the price.

    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.
  4. 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.

    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).

  7. 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

    Article: Klipsch - The Three - Review

    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.

    Article: Roon 1.3 Major Update Coming Today

    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.

    Sonic transporter for HQP directly into DAC??

    Might also consider one of these to power the sonicTransporter (12v) & Regen (variable 9v adjusted to 7.5v). HDPLEX Fanless Linear Power Supply for PC Audio and CE device

    Sonic transporter for HQP directly into DAC??

    Given that you want to stay away from the microRendu due to the Linux incompatibility with those DAC's, you still might to consider adding an USB Regen from Uptone in order to clean up the USB signal.
  14. One of the new features of Roon 1.3 (I believe it is new) is to include the DR information for each album. Very interesting to see.
