When I did AudioKarma Fests, where forum members could rent rooms in a hotel so demo their systems to other forum members. So, I would bring a small wireless router (PW protected) which had an ethernet switch and a mini-PC with Daphile and Music loaded on it. I would use an old android pad for control. Just me.

The new option for U1: Internal SATA Power Plug is added for connection normal ATX power supply inside the music server. Internal OCXO Edition for customer addon option. Purchase Link

We just complete the build for X1 Ethernet Server Adapter and U1 USB card for one Audiophile. He is using the HDPlex ATX power supply for his music server. We made to order the new SATA power plug for him. The dc cable is using Duelund Audio from Holland. Very smooth sounding and almost become standard wire we use everyday. We are quite happy to made to order the new option for most customers with different requirements. The new option for Internal SATA Power Plug is added today. Purchase Link

The rooms I set up had no problems during the outage. I provided local music playback!!

That’s impressive. I might be tempted to upgrade from HQPlayer 4 if there was a more affordable path. The other way to get lip-sync in DSD, e.g. for people like me who have the older version, is to add a delay to the picture in apps like VLC or Kodi. That’s very interesting, and may support the theory I’ve been working with for a while now. Others have pointed out (e.g., Amir and others on ASR) that when you’re using flat speakers with excellent dispersion, like the KH120s, you don’t need to overdo the room treatment, and that may also be true for EQ. Their on-axis response is already flat, and the off-axis response is quite smooth. Plus, a good immersive mix will have greater direct sound energy from the other speakers than from reflections, and that energy will arrive before any reflections if the speakers are time-aligned. So nail the delay and reduce some of the bass loading from SBIR/room modes, and you’re pretty much set. You can also treat first reflections in the room, but no need to make it too dead. When I average the responses of all my speakers, I get something very close to a flat response without EQ. Re XO, the KH120s go low enough that it’s rare I notice the difference that a bass-managed sub makes (or that my O 300s make in the bass), when it’s balanced properly. But I don’t do much listening at high SPL, and therefore distortion is not a factor. On the benefits of DSD256, I will not argue with you :-)

I don't remember where I heard this album. Bach on a tuba. Amazing artistry here and good lungs😱

This one is great. Amazing band, consisting of members of Fugazi!

I love it! Off topic - This one made me think of you - https://www.independent.co.uk/news/world/americas/titan-submarine-implosion-navy-debris-microphones-b2362685.html

It is the largest factor affecting speed of sound! Humidity to lesser extent. Altitude to some extent if one lives high up on a mountain. And in sea water, also depth (pressure) and salinity. 😅😜 But in this case, we are not underwater, although that's the acoustic environment I feel most home at.

The ultimate audiophile move - air temperature!

Pi5 Upgrade I decided to build a slightly different version. Pi5 8Gb Pi 27W supply Pi5 case Pi5 Active Cooler Inland 4TB SSD USB for music (Reuse 480GB Sandisk for boot) I formatted the 4TB drive to ext4 and installed drivers on my Mac to copy my music library to the drive: The 480GB drive has the OS installed: Then I SSHed into the Pi and turned on VNC. From the Mac I then use the Pi to setup. The Audirvana beta. I changed the ownership and set permissions of the "media" folder and subfolders on the Music drive so Audirvana can access them. Then I used the setup script to run the application as a service and start it. In the next post I will setup the Audirvana Remote

Like I said, I have owned for a year. No issues. Heck, I have owned my TEAC UD-501 for 8 years already. Before that had an SMSL that died after the 90 day warranty expired. I also have an old version of the iFi NANO. 3 versions before MQA was introduced to it. I lost the flash drive with the drivers, so I took it to AXPONA to ask iFi. They were amazed I had the original packaging that they took a picture of me holding it for the factory. Quite fun.

Some of the larger images use atmos, if I am not mistaken.

I was in one room where they played an MQA file as it showed up on the display. No one mentioned it or took notice of it. That was the only time in three days.

Hello folks - first time poster here and a potential buyer of this DAC. I see the HDMI Module on this DAC supports CEC for volume change using TV remote - can someone confirm if the TV also sends power-on signal on the HDMI ARC CEC so that the DAC is turned on at the same time as well?

Even if I decide I like the R26 better than the PS Audio DS DAC, I'm probably going to exchange this one. A day of not functioning, then sudden functioning, is not a good sign for long-term reliability. I'm comparing it first to my previous DAC, a custom modified Gustard x20pro. The x20pro is an earlier model and not up to their latest standards, stock, but the guy I use for mods did some pretty cool stuff to it. Bypass caps all over the underside of the circuit board to stabilize power, grounded strips of ERS paper to reduce RFI, damping material on the crystal, beefing up the power supply. It sounds awesome. So far, on first listen to the R26, the R26 is nowhere near as dynamic and extended as my x20pro. But I'll give it some time. Also, I may have the same guy modify the R26.

If you like, you can also specify delays as distances, and if you want to be really precise, you can also specify air temperature.

No processor can come close to that!

Commercial theaters are set up for movies. Completely different perspectives vs. a dedicated listening space. My HT is set up for both movies and Atmos music. So, it can be done, but for just two or three folks. I have yet to hear a commercial theater or large theater space with many, many speakers reproduce Atmos music well. So Chris, I am not surprised with your experience, the disc will no doubt be a much better experience for you.

Talking about channel calibration... I personally prefer using REW in 1/3 octave RTA mode to do the SPL calibration at 85dBC based on reference -20dBFS wide band pink noise. @The Computer Audiophile I upgraded my speakers to Neumann KH120A (level x7 and height x4) recently. Followed Neumann's document I adjusted the EQ switches on the speaker's back panel for reducing the wall and ceiling bass reflections, and also adjusted the treble to follow the Atmos music curve. The result was satisfied to me: After done SPL calibration process, I found I just needed the time delay and some single point EQ (for >3dB peak below Schroeder frequency). I put it into HQPlayer's matrix pipeline and here's the example: Thanks to @Miska the recent version of HQP5 has minimum buffer option can let me upsampling to 13ch DSD256 without lip-sync issue while watching Atmos 7.1.4 movies. Movie with MCH DSD256 the SQ is soooo amazing! Compare the basic EQ to FIR partial / full corrections, now I like the basic EQ this time, even it has no XO. 😃

fw 17.2 brings a Spotify Connect SDK regression to 3.199.422 ? :-/ (... not that I am using Spotify 😂)

It seems there are more shows being announced in Chicago. Last year this time, almost nothing was announced, now I could almost go every day of the week, if I had the cash.
