  1. Read mansr’s objective review of the Cobalt on this site. Bad performance at a high price.
  2. With the Audioquest DACs out of the picture, given their abysmal performance, one wonders where to turn for a DAC to attach to an iOS device to listen to Roon. I bought an SMSL Idea DAC for this purpose, and it sounds great, but I can seldom get it to work with Roon. It’s mostly silence or clicking. It works fine with all other apps, but Roon works in a different way. When I do get it to work Roon can send it audio up to 768Khz, but that is one time in a hundred. Does anyone know of a DAC that works with Roon and iOS for headphone listening?

  4. Any speaker that employs DSP for crossovers and equalization would have to convert the audio to PCM in any event.
  5. Actually, many of us with projectors use HDMI cables that are much longer than 15 feet. As for the observation by Fitzcaraldo215 that Nvidia graphics cards weren’t able in the past to do 88.4 and 176.8 kHz audio, that is no longer true with the latest drivers. Finally, I routinely listen to multichannel music using the HDMI outputs of my Windows computer (employing JRiver) and my Roon ROCK. Both sound very good to me.
  6. I use Roon on a NUC running ROCK and JRiver on a Windows PC to listen to multichannel music over HDMI. I generally find both quite listenable using ARC for room eq on my Anthem processor. If I was looking for a very low cost way to listen to multichannel music stored elsewhere using HDMI, I'd explore one of the $50 Amlogic s905x boxes running Kodi, which are fully capable of delivering multichannel audio over HDMI. I'd likely drop Android in favor of LibreElec, which is "just enough OS to run Kodi." Kodi has a nice interface and can be controlled via mobile apps. Others report that they do this with great success.
  7. I'm in the trial phase of using Roon, having waited until 1.3 because multichannel music is important to me. I built a fanless NUC and loaded ROCK, Roon's OS. For several years I've used JRiver Media Center, which deals with multichannel music via HDMI correctly in my experience. That is, when I play two-channel music my Anthem processor sees the signal as 2.0 channel audio and treats it accordingly. Thus, I can listen in stereo or in Anthem Music, a subtle up-mixing mode that I sometimes like to use. When I play multichannel music the processor sees it as such and treats it as such. But in Roon (using ROCK) my options for HDMI are to select 2.0, 5.1, or 7.1 channels. Apparently If I select 5.1 or 7.1 Roon always puts out that many channels, with some channels silent if the music has fewer channels. My processor always sees this as a multichannel signal, so the Anthem Music upmixing mode is not available. I can get it to upmix two-channel music by changing the HDMI output to 2.0, but then it won't pass multichannel music. This is very unfortunate, and potentially a deal breaker if true. By the way, all of my multichannel processors and receivers work this way. The upmixing modes I want to use only work with two-channel signals. Have I got this wrong? Is there some setting I've missed or some way to get it to work the way I want?
  8. I'm putting a NUC7i5bnk in an Akasa Plato 7, and have a couple of questions. Should I turn off the fan in the BIOS, and should I use the Akasa-supplied CPU/GPU heat sink pads or heat sink compound? Someone who documented his NUC-Akasa build on YouTube said Mastergel heat sink compound gave him much better thermal behavior than the pads.
  9. But with existing recordings they claim upon encoding to be removing or lessening preresponse "blur" caused by processes such as sample rate conversion by delaying it relative to the response. Is this the same as using an apodizing filter on a DAC upon playback?
  10. They say that during MQA encoding they employee DSP to delay the preresponses cause by the linear filters previously used in the recording process. Do you know this not to be the case? Have you tested (and could you test) any of the MQA 2L files against originals to try to determine whether they employed this "debluring?"
  11. I've been thinking about buying a Mini as an inexpensive way to experience both MQA and Tidal. Like many I was frustrated by the sudden withdrawal of MQA at CES, but hope to see this issue resolved. Does anyone have news about Auralic and MQA that can be shared? It seems to me that this news blackout has extended a long time, especially given that other manufacturers are now providing MQA support. Any information would be greatly appreciated.
  12. J. River Media Center 15 can be controlled by any device on your local network that has a browser, such as an iPhone using Safari. All you have to do is to go to Tools, Options, and tick "Share your library, playlists, and views." You will see that the TCP default port is 52199. Find out the ip address of the computer running Media Center, and point to it and the port using the browser on your mobile device. For example, if the computer has an address of 192.168.1.253, you'd type this in the browser address: http://192.168.1.253:52199/WebRemote/ .From WebRemote you can control most aspects of Media Center, including the library and playback. To find out the ip address of the computer, go to start, and get the command prompt by typing in "cmd" in the box or by clicking on "run." When the command window opens, type in "ipconfig /all". The response from the computer will include the ip address.
