  1. Hi Jose, I am running SOSE Version 2.3 into an Arcam irDAC along with JRiver v20 on two Windows 8.1 computers. Last night when I tried to play music using JRemote on my iPad, SOSE was not listed from either computer. It has disappeared from the network. SOSE showed up normally when I put its IP address (reserved via my router) in the browser (Safari). It showed that MPD/DLNA is active on the Audio App Switcher page. After rebooting computers, rebooting the SOSE and power recyling it, it showed up on the network for JRiver. Do you know what might be the cause of its disappearance? Is there a way to keep awake/available all the time? Thanks,
  2. If the laptop is connected to TV, the receiver is not getting the signal. If the laptop is connected to the receiver and the receiver is connected to the TV, the sound will come out the speakers connected to the receiver as well as from the speakers on the TV.
  3. Good luck with your plan of using the video card. For about the same amount money as the ATI 5750 card, one can also get a standalone hardware streamer to play videos including Blu-ray rips. Which software player are you planning to use? Last time I looked, the Windows MC could not play Blu-ray bitrate video from the disc or rips. It may still be true with the Windows 7. 1) Yes, it is possible. The HDMI audio could be set as the default to be used by Windows MC. The Lynx card could be selected by a competent software audio player such as the J River MC or even Foobar2000. 2) Most current AV receivers have the same BB (now TI) 24/192 DAC chip built-in but the similarity with a standalone DAC stops right here. There is more to a DAC than a chip. A good AV receiver with the DAC as good as a standalone one would cost a lot of more to say the least. A system can only be as good as its weakest link. If the AVR is not the weakest link, it would sound very nice.
  4. At this point of time, standalone DACs are two channels only. A handful few support DSD but it may still be 2 channels only. There are essentially two worlds out there, the HT/HTPC world with AVRs supporting multi-channel LPCM, Dolby TrueHD and DTS-MA, and the audiophile world with stereo only audio supported by pretty much every standalone DAC. Two do not seem to mix, at least not yet. The HD audio means different things to different people. The movie folks want uncompressed audio from Blu-ray discs, typically presented as Dolby TrueHD or DTS-MA. The CA readers here are mostly interested in the 24/88.2, 24/96, 24/176.4 and 24/192 PCM files in uncompressed (wav or aiff) or losslessly compressed (flac, alac) formats stored on a computer, likely an HTPC but for music only. To make things even most complicated, the HTPCs are caught in the middle of Blu-ray players and dedicated video streamers such as Dune Base 3.0, PCH C-200 or WDTV Live Plus. It is not very straightforward to support TrueHD and DTS-MA from a PC due to the HDCP handshaking requirements. The Blu-ray player will always work. A well-designed standalone player using the same Sigma chips can do equally well. I started out with an AVR with an HTPC and ended up with a hybrid system incorporating an AVR and an standalone amp. For music, the sound comes from the HTPC, controlled by the J River MC out through the Musical Fidelity (MF) V-Link async USB to S/PDIF converter into the MF V-DAC, through a tube stage and then finally into the standalone amp. For movies, either the Blu-ray player or Dune Base 3.0 streamer provides the HTMI output to the AVR with the front channels pre-out into the standalone amp. The subs are connected to the standalone amp to benefit both the 2 channel music and movies. You could start with an AVR and expand from there. Good luck!
  5. I downloaded the latest 1.4 version and tried on my HTPC, a dual core system with 3GB memory running Windows 7 Ultimate 32-bit. I selected the Audiophile option. After setting it, JRMC 1.5 sounded harsher and sandier than before. I restored the saved system restore point. Now I know that the Fidelizer does not make permanent changes, I may just reboot should I try again. Audio hardware: M2Tech hiFace -> Musical Fidelity M1 DAC -> NAD C375BEE Audio Software: JRMC 1.5 (15.0.174), WASAPI Event Style (100ms buffer), no resampling, source bit depth I have a V-Link on order and may try Fidelizer again when it arrives.
  6. I just tried the Fidelizer on my workstation (not the HTPC). I do not like the scheme changes (no more Areo schemes) and the Windwows Firewall has also been stopped. Is there a way to undo all the changes? Thanks, | Update: The Windows System Restore took care the undo. I may try the Fidelizer on my HTPC system but I will definitely create a system restore point first.
  7. Thank you, Chris. My M1 DAC is coming next week. Since I already bought the hiFace, I will be using it to start. If the V-Link sounds better than the hiFace connecting to the M1 DAC, I will probably consider. I was hoping that the V-Link would support 24/192 to match up with the M1 DAC. At 24/96, the 24/192 capability of the M1 DAC would be lost.
  8. Alan, The Wavelength Proton has a volume control on the desktop and the volume setting is passed down to the Proton. The Proton takes the value and sets the volume in its analog circuit. http://www.computeraudiophile.com/content/Wavelength-Audio-Proton-DAC
  9. ReplayGain is handy to keep output levels more consistent for the various albums (classical) or tracks (non-classical). However, the notion of changing volume digitally instantly triggers alarms - quality degradation, non-bit perfect, etc, to name a few. The Proton has done something rather intelligent. Its seemingly digital volume control is actually done in the analog stage, the right way for the digital age. Can the same principle be applied to ReplayGain so the DACs adjust the volume based on the ReplayGain value in the analog preamp stage?
  10. I was mistaken. The Vista x64 machine leaks just as much as the 32-bit Windows 7 machine. The process name is the same. See J. River Interact forum thread referenced in the previous post for updates.
  11. JRMC is the best but it has a memory leak issue which I am investigating. I reported on the J. River Interact forum. Here is the link to that thread. http://yabb.jriver.com/interact/index.php?topic=60337.msg407402#msg407402 The problem occurs when one uses the theater view mode with the slide show mode turned on and set the size value to less than 100% under the Appearance section of the Theater View on the Options panel.
  12. Additional information: I found the MC on the Windows 7 machine had the Theater View Appearance Size set to 90%. Once I set it to 100%, the memory became stable. However, on my Vista x64 PC with 8GB memory. the MC process memory footprint stayed the same (7464KB) regardless what I do. It is now set to have the slideshow and the size is set to 90%. The memory stays exactly the same, 7464KB. Now on the Windows 7 32-bit machine, the MC process image name is called Media Center 15.exe under the Task Manager. On the Vista 64-bit machine, the image name is called JRService.exe *32. Both are running J. River Media Center 15.0.142. On both machines the shortcut indicates the executable name is "Media Center 15.exe". For further information, you can follow the thread on J. River's Interact forum. http://yabb.jriver.com/interact/index.php?topic=60337.msg407402#msg407402
  13. I just started using JR MC on an HTPC running the Windows 7 Ultimate 32-bit. The system has 2GB memory and connected to a 1080p HDTV as the monitor. The sound device is the hiFace USB to SPDIF device made by M2Tech. The output of the hiFace goes into the Musical Fidelity M1 DAC's coax input. The J. River MC is set to use the Kernel Streaming mode. The JRMC was set to play all the albums(924)/songs(7068) in the "theater view" mode in order to properly "burn-in" the M1 DAC. The music files are all lossless WMA format. Most are from the regular CD rip at 16-bit/44.1kHz. About 33 songs were from the HDTrack at 24-bit/96kHz. They were downloaded as FLAC and converted to WMA with dbPoweramp. After 16 hours, I noticed although the music was playing, the JRMC was not responding to the remote, mouse or keyboard. The Windows Task Manager showed the JRMC process was using over 1.7GB memory. After terminating JRMC and restarted it to play all the songs, the initial memory footprint was 279MB. After 1 hour, it became 479MB and was increasing. Once the playing stopped, the memory stayed the same and the extra memory was not released. I also posted this on the J. River Interact forum. Has anyone encountered this problem or a similar memory leak problem?
  14. "#1) Build the computer with a motherboard that has daul LAN ports, Then add a receiver and speaker system connected through the LAN." Years ago I had a Yamaha receiver that had a LAN port and could play WAV and MP3 files. But the interface was horrid. I gave up and bought a Roku SoundBridge (discontinued) instead. I am not sure at this point any receiver will have any decent interface to play music and with wide format support. If it can support FLAC, it can work but the interface might still be pretty prmetitive. "#2) Buy a motherboard that has an optical audio output and connect that a receiver and speakers." I found the MB onboard sound is generally worse than a $40 Turtle Beach sound card, even from one of latest ASUS MBs. #3) Add a dedicated sound card to the computer and run an optical cable from that to the receiver." For about $150, the HRT Music Streamer II USB DAC makes a much better choice. It has the latest asynchronous USB support (instead of the jittery adaptive type for this price range). There are many good DACs based on the adaptive USB interface but a lot of money has been spent on correcting and filtering to reduce the jitter. The following simple setup should yield fairly good sound without too much cost. 1. The HRT Music Streamer II (or splurge for the II+) 2. A decent but economical 2 channel integrated amp 3. A pair of decent but economical speakers 4. A decent and economical subwoofer (optional)
  15. You could try using an AV receiver with its built-in 5.1/7.1 TrueHD/DTS-MA DAC combined with a standalone integrated amp with an optional HT-bypass. In the pure 2-ch music mode, run the 2-ch DAC such as the HRT Streamer II to the quality integrated amp to drive two front speakers and an optional subwoofer. In the 5.1/7.1 HT mode, let the receiver handle the decoding. Run the pre-out for the front L and R channels into the quality 2-ch integrated amp. Let the receiver drive the center and surround speakers. The HT bypass option could be used to avoid amplifying the HT front channel signal twice and to keep the volume level fixed for the HT use. But this optional is not essential IMHO. The receiver can be further expanded with a DSP processor feeding to a multi-channel or of mono-block power amps. The quality integrated amp can be expanded with a quality preamp feeding to the same multi-channel or mono-block power amps.
