Unless I am mistaken Angelo’s case is designed to perfectly fit either the DIY Extreme or the DIY Olympus builds. My plan is to install my DIY Extreme in it now, gaining better cooling and rigidity in the process. Someday, I’ll re-purpose the case for a DIY Olympus build.

Are you using stranded CAW to replace solid SG in signal cables as well as power cables? Are you saying that in these applications the stranded CAW has as exquisite an openness in the middle through highest frequencies as the SG?

From the SuperMicro installation guide:

Ohf course I have a clone of my C: drive, but, unfortunately it goes all the way back to the original installation and includes programs and features that I have since found compromise the SQ. I have been carefully stripping out Windows “features” and services, one by one, for several months now. The result is much richer, fuller, and more fleshed-out SQ, with a previously unheard additional nuances of musical performances emerging from the blackground, even on very familiar recordings that I have used as references for many years. I have tried other minimal footprint operating systems such as Euphony, AudioLinux, etc, and found them to ultimately sound a bit thin and shallow in comparison. The process of identifying services that you can live without can be a very tedious trial and error process, and the interdependencies among them is a PITA. But the SQ rewards are definitely worth the trouble.

OK. Does anyone else have a link to a “restore services” utility that they can recommend?

Miska, can you provide a link to a “restore services to default” utility?

It turns out that I am unable to get HQPlayer to show up on HQPlayer Client. In my attempts to disable all unnecessary services, I might have shut down one that is necessary for HQPlayer to access the network.

Thanks Miska! That’s something that I hadn’t checked out. Will do.

Intel SSPED1D280GA with music loaded to HQPlayer 5 Desktop using the “Browse” button on the desktop

I am running a stripped down version of Windows 10E LTSE version 1809 on an Asus WS621E Sage motherboard with dual Xenon processors and 48 GB RAM with a USB connected RME ADI-2 DAC FS set to DSD Direct. I am running HQPlayer 5 Desktop with poly-sinc-gauss-long as the Oversampling Nx, ASDM7 as the Modulator, with 44.1k X 256 Bitrate / Limit, IIR Integrator, and Wide Conversion. When I leave the system on overnight and neither connected to the internet nor playing any music, I am getting absolutely superb SQ with local files. But after about 2 minutes of playing the first track of a listening session, I get the first incidence of stuttering at about 2 minutes. Then at 2’32 I get the second incidence of stuttering. Then the 3rd at 2’38, the 4th at 2’42, the 5th at 2’44, and so on. I have used Process Lasso to check processor utilization during HQPlayer play, and it is very evenly spread across all cores, with none much greater than 10 to 20% at any time. Memory utilization is negligible. I have checked to make sure that none of the other programs on the server are automatically checking for updates, and having the network connected or disconnected does not seem to effect the stuttering problem, one way or the other. When the network is connected, I can use the Qobuz windows app to play its highest resolution music without any stuttering at all, which is also the case when I use HQPlayer to play local files at less demanding upsampling configurations. Suggestions?

400 Watt power supply may not be up to the task. I once tried to use a HDPLEX LPS as a temporary supply to listen to while I was modding my Nenon V3, and it quickly overheated and shut down.

My ADI-2 DAC fs is connected with balanced output cables to a Schit Jotunheim, and then on to RAAL SR1a headphones. Thank you so much for the suggestion!

Thanks for the suggestion. Following bogi’s suggestion, I went back and simplified the fine tuning settings that I had imported from my Gaia / Terminator Plus setup. That has gotten the music playing PCM now. 😅 I will now begin fine tuning for best PCM SQ. Next, I will export the settings for later reference, and then I will bypass the SU-6, going directly from the music server to the ADI-2 DAC, and fine tuning that for best SQ too. Thanks !

Thanks. I appreciate the suggestion. I will change the HQPlayer settings to accordingly.

Thank you for the reply. I very much prefer the SQ of Qobuz played through HQPlayer and converted to DSD 256. I have no problem getting that to work on my Gaia / Terminator Plus system. This is my headphone system, which substitutes the SU-6 / ADI -2 DAC fs. I am using the Qobuz windows player to confirm that, at least with the Qobuz windows player, the SU-6 / ADI-2 DAC fs are connected properly and capable of playing music.
