  1. Comparing a scalpel to sabre is kind of nonsensical. LPS 1.2 current limits limit its use to low power endpoint. There it is superb. Cannot use it though to power a server with CPU "guts". Question to ask is how does this compare to an SR-4, which is at like price point and can power a more current hungry device? Like the multiple outputs of an HDPlex but have a sour taste in my mouth from the HDPlex100 that just stopped working last year... I expect my electronics to last into obsolescence.
  2. The main difference is gapless playback. In general I found Openhome more pleasing to use than plain vanilla UPNP but it is important that the endpoint device support Openhome natively or you will get quirky behavior when trying to manipulate whats playing. Used with the linux version of Minimserver, it will get you to the limits of what UPNP protocol can do for SQ.
  3. Was Lucas a cousin to Murphy? I'm guessing he had some role in the manufacture of Triumphs and MG's?
  4. if you have no experience with tinnitus, here is how you can duplicate it 1) find an old 25" picture tube TV that still works 2) take the back of the TV and turn it on 3) sit with your ear near to the back of the picture tube and enjoy that ultrasonic like hum 4) record it and then have someone randomly raise and lower the volume level during your day So not an impediment to getting value out of a quality system but when the tinnitus "volume gets turned up", not a great time to do any listening that requires analytic concentration.... better to go watch /listen to blue ray movies with lots of explosions and crashes 😉
  5. mmm, and which of the 3~7 schools of psychology would psychoacoustics fall into? Anyone out there who has reached the age where tinnitus is personally real knows how primitive the medical science of hearing is.
  6. you have a piece of software meant to work locally, not integrated with streaming to another device. See if the manufacturer can help, perhaps has a different product for streaming. An option you might want to consider is a second machine like a NUC running the same software setup.
  7. There are 2 things you want for a Roon USB out endpoint 1) the best power supply you can afford 2) no active media drives attached to the endpoint contaminating the USB output signal. The degradation of CD quality tracks is not trivial when I try to use same AL NUC 7PJYH as a 1 box USB out solution vs using the same AL/NUC as Roon server to an AL/RPI endpoint or using an AMD PC as AL/Roon server to the NUC7PJYH as endpoint. The RAM root feature of Audiolinux makes a drive-less endpoint possible The hardware of the endpoint matters for speed of execution; in the example above, although CD quality sounds good with RPI, DSD stutters. No such issues with the 7PJYH but when compared to a faster processor for endpoint its not quite as smooth for sound I'm sure you can build a one box solution with the right technical wizardry but suspect the cost to do so will always be much higher than running separate core and endpoint. Server also matters for Roon core streaming but the electrical isolation and power supply challenges are less critical , "outsourced" if you will to the USB endpoint.
  8. there's a world of difference between using USB power to power the USB receiver chip vs using it to power the DAC circuitry also...
  9. The thread below includes people who ended up switching from the original fine Innuos product to a NUC solution using Audiolinux. There is certainly a big cost differential between the NUC Audiolinux/Roon approach vs using the Innuos Zenith Mk III ($4200) In your shoes I would buy a NUC first to use as Audiolinux Roon endpoint with a high quality power supply such as Uptone Audio LPS 1.2 or Paul Hynes SR-4. You will need to read carefully the NUC BIOS power tweaking recommendations for getting best USB performance, (and to make sure that the NUC will run if you use the low current LPS 1.2) but the cost is very small compared to the vast improvement rendered from correctly setting up a NUC as Roon endpoint. The AL setup part for Roonbridge is trivial, select Roonbridge for playback in the menu, then enable RAM root. So far all comments I have seen indicate that Audiolinux Roon server is superior to running Rock on same NUC. Eventually you will want a more powerful CPU in your Roonserver but you can defer that decision so long as the current NAS works fine as Roonserver
  10. Nothing wrong with CD player that good built in buffer and read error correction can't solve... its just a dumbed down version of a computer. The improvements from better power supplies used with computer audio playback does have me wondering what my Linn CD player could sound like if I knew how to put in a better PS
  11. @The Computer Audiophile hi chris. Customer care request thread obviously in wrong place, can you move to the Allo products sponsored forum?
  12. PS Audio has been doing this for a long time. You may want to do some research on their site https://www.psaudio.com/product-category/ac-regenerators/
  13. seems 64 bit doesn't tolerate the presence of an unused Digiplus hat as 32 bit does. Back to prior limitation of 44.1/16 bit after hat removed.
  14. Gigabit powerline Ethernet works much better for me than using wifi options with audio. Plug 1 end into a switch at the audio system,the other into the wifi router, connect audio gear to switch. Does require that it be plugged directly into wall socket.
  15. I'm still having problems getting RPI3b+ with 64bit AL as Roonbridge to work with Schiit Eitr . Was getting stop and go play on CD quality, electronic noise on other resolutions, then did a fresh install with all updates, now all I get a fraction of a second play at start of new playlist, otherwise no sound at all, synch light is on for the Eitr. 32 bit works flawlessly Anyone seen/fixed similar issue?
