My current setup is based on dual-PC's with Windows Server 2012 with AudioPhil's optimisation and JPlay in streamer mode. My audio PC is Intel NUC headless and fanless with passive cooling in Tranquil case, OS is on SSD.
I heard that Linux based dedicated servers are much better for audiophile purposes than Windows but I have no audio experience on Linux based servers. Do you think PK90 will be better than my dual-PC setup? Is it really worth switching from my current setup to PK90?
I couldn't find any technical info on PK90 such as what kind o storage is used for OS (SSD or HDD), motherboard info, version of Linux, details of SoTM card. I also could't find any info on setting up PK90. Can you shed some light on it?
You help and advise is highly appreciated!
I'll eventually be doing a full review of the PK90 over Part Time Audiophile when I have some time. But to answer your specific questions:
*I don't know if the PK90 will be superior to your setup, because I haven't heard your setup. Many people like Linux servers for transports and find them to sound best, but some disagree. Personally I think my PK90 sounds better than my other systems but those systems still sound great in their own right. Keep in mind that the PK90 is strictly a music server only - you can't do anything else with it whatsoever. So you'll still need some other computer to rip discs or download music or whatever else you want to do.
*PK90 uses an SSD for OS, and it's configured as read-only so the end user can never screw it up.
*I don't recall the specific motherboard but it's an Intel chipset and uses a passively cooled Atom CPU, which is more powerful than the Bryston BDP-1 (which Auraliti helped develop) that uses an Alix board. I think the new BDP-2 upgrades from Alix to something more powerful, but I'm not sure what it is.
*They use their own software which is basically a tweaked Voyage Linux, heavily forked from the original but similar overall to the current Voyage MPD (which was developed independently but ended up in roughly the same place).
*The SOtM card is the tX-USB card which sells separately for $300-350 depending on where you live.
Setup is simple - you'll need a network connection via Ethernet, in order to control the system. Actual playback can be from files on a USB attached hard drive or else via NAS though I haven't done that myself. Basically you connect it to the network and it gets assigned an IP address. You then use that IP address to log in through any other computer on the network. Auraliti gives a basic menu and you can control playback through a browser if you want, or use a dedicated bit of software. There are options for PC, Mac, Android, and iPad/iPhone. Obviously you connect a USB DAC to the SOtM output card, and then you're all set.
