  1. Hi George To setup the Lumin D1 to internally convert to DSD before sending the signal to the inbuilt Wolfson WM8741 DAC chips, do the following. In the Lumin app, go to Setup (the cog symbol). Under “Lumin” select “Option”, which will switch to a new window. Scroll down to “Re-sampling”. There are 2 options: Off (the default) or Custom. Select “Custom”, that will bring up the up-sampling options for each of the input sample rates. Then for each of the the sample rates 96kHz PCM, 88.2kHz, 48kHz, 44.1kHz select “DSD”. For 176.4kHz PCM files and above there is no DSD option as the Lumin D1 only offers DSD conversion prior to sending to the inbuilt Wolfson WM8741 DAC chips for source material of 96kHz and below. I leave mine DSD conversion For 2.5mm to 2.1mm DC barrel adapters in the UK you can try: CCTV 2.5mm Female Socket to 2.1mm Male Plug Power Adapter Converter | eBay or DC POWER ADAPTER CABLE 2.5MM x 5.5MM FEMALE to 2.1MM x 5.5MM MALE - 12CM | eBay The above adapters will let you use the 12V LPSU on the D1 if your LPSU has a 2.5mm DC jack. However, I think some Cambridge Audio DACs use 2.5mm jacks and some use a 3.0mm DC jacks. I am not sure which one you have and your linear power power supply was built for. If the output jack on the LPSU is not 2.5mm you will need a different adapter. I suggest emailing David Brook at MCRU (a good guy who is usually very responsive) to see what the size is of the jack on the MCRU LPSU he supplied to you.
  2. George, depending on the size of the barrel of the MCRU/Longdog LPSU you may be able to use it with the D1 with a simple barrel size converter, e.g. https://www.amazon.com/gp/aw/d/B00MJU7NFO There is no consistency amongst audio equipment as to the size of the DC plugs in (the most common sizes being 5.5 x 2.1mm and 5.5 x 2.5mm) so I keep a handful of converters at hand. Also the D1 can internally up sample to DSD64. For some reason upsampling, is turned off by default but you can turn it on in the settings on the Lumin app. Sent from my M3 Max using Computer Audiophile mobile app
  3. Another factor in the choice of Cat 6, Cat 6A cables, or fiber cable, when rewiring a home is the fire rating of the cable. If you are running the cable through the ceiling space or under false ceilings you need plenum rated cable to meet fire regulations in many countries, including the United States. Sometimes plenum rated cable is referred to as "CMP" or, for fiber, it is called OFNP. The majority of cables are rated for "riser" ducts - ie. enclosed vertical ducts where there is not much airflow. In the open ceiling spaces with little to impede a fire spreading fast across the whole house through flammable material in the ceiling and since there is a normally a good supply of oxygen in ceiling spaces, a higher fire rating is required. Riser cable is often called "CMR" or, for fiber, "OFNR". Plenum cable is often referred to as "CMP" or, for fiber, "OFNP". The Blue Jeans Cat 6 and Cat 6A cables many of us are fans of are CMR cables - so not rated for ceiling spaces. For Cat 6 or 6A, CMP/Plenum cable is normally a significant extra cost.

  5. Miska and others HQP allows for a headphone feed via the Matrix pipeline functionality. The lchannel evels Miska uses in his 5.1 to stereo are set out in his post above. I am more interested in a 2 stereo to 2 stereo with cross-feed. It involves splitting each of the left (1) and right (2) "source" channels twice, with each one going to both the left (1) and right (2) "mix" channels with a filter being applied at least to mix channel of the opposite channel (and potentially to all of the mix channels). My question is that if you already have headphone cross feed plugin that works with other software (e.g. Redline Monitor, Isone Pro, Bauer stereophonic-to-binaural DSP, AU or VST plugins) or an external device (e.g. SPL Phonitor 2) that you like, can you send a test signal to through those plugins to create the FIR convolution filter for use in HQPlayers' matrix engine? In essence, all the plugins apply in different degrees of time and phase delay between the channels and usually a tone roll off on the treble (to simulate the fact that treble reflections in a room are generally rolled off by the room furnishings and surfaces). Presumably, there must be a way to send a signal through the external processor or plugins to general the convolution filters that can then be used by HQP. I am familiar with the filters created by Audiolense room correction software that can be used with HQP. But I do not know how to create the filters by running a signal through a known DSP headphone processing plugin (or external unit) to create a convolution filter. Can anyone provide some assistance on how to do this? If so, it would make setting up headphone cross feed in HQP a much easier task.
  6. Hi Jesus If you can add Lumin to the supported list it would be appreciated. I have a Lumin D1 in my secondary system in my study and it would be great to be able to send it hi res files via Roon. Currently that is only possible to connect to the Lumin from Roon in airport mode which involves a lower resolution. Thanks
  7. Hi Miska In 3.14b7 on Mac Yosemite 10.10.5 the Tools ->Speaker Setup window keeps de-enabling itself. I go in enable it click ok. When I go back it is not enabled (though it remembers the settings selected in the window).
  8. For those of you in Australia, do you have any recommendations as to good quality power receptacles here? Nearly all of the higher quality receptacles advertised are US / Shucko / UK, but not AU. Any recommendations welcome.
  9. Hi Hailey Like you I use headphones for many hours at work each day. I have a SPL Phonitor 2 which I am very happy with. It sounds great with my Audeze LCD-XC. I run it from a Exasound e12 DAC. The Phonitor 2 has both balanced and single inputs and outputs. SPL’s background is professional studio equipment and the SPL Phonitor 2 was designed for that environment. It works really well as a headphone amp. I find it is better than the well regarded built-in headphone amplifier of the Chord Hugo (which I also own) and much better than the Oppo HA-1 which I tried. Generally it has more space, tighter bass and excellent transients. I bought it before the iFi iCan Pro so I cannot give you a direct comparison between those. You will find some very favourable reviews of the SPL Phonitor2 that give more details. I will mention that a benefit of the Phonitor 2 is that it contains the most flexible cross feed controls that I am aware of. It is a personal taste whether you want cross feed controls (to reduce listening fatigue while listening to headphones particularly for long sessions). If you do the Phonitor 2 has a very flexible setup in that you can adjust a number of parameters individually, rather than simply having 2 or 3 presets and dial it up as much or turn it down to as little as you like. I use its cross feed all the time. One and a Half in another thread also said that once he used the Phonitor’s crossfeed he hasn’t switched it off. (See the thread: http://www.computeraudiophile.com/f12-headphones-and-speakers/spl-phonitor-2-a-20232/ ) One and Half has now moved from an Audeze to LCD-3 to the HD800S, so you might pm him to ask how he finds the combination with the SPL Phonitor 2. For what it is worth, I also really like the tactile feel of the large volume control knob. Sitting in my workspace, I use the volume control frequently during the day. BHPhoto is currently selling the silver version of the SPL Phonitor 2 for $1,599 SPL Phonitor 2 Headphone Amplifier (Silver) SPLPHON2SL B&H Photo A quirk with the Phonitor 2 has a quirk is that the balanced output is two 3 pin male XLR on the rear of the unit, rather than a 4 pin balanced output in the front. You can either have your headphone leads terminated to work with those outputs, or get a short converter from the two 3 pin XLR to a single 4 pin balanced plug (which is how I use it). SPL recently introduced a big brother, Phonitor X, which has a 4 pin XLR balanced output, but costs substantially more and loses one of the 3 cross feed controls (the centre reduction, which I find useful). If you get a chance to try one out see how how it works with your headphones. Regards AudioTragic
  10. Yes, this is quite easy to process DSD + DSP room correction in HQPlayer. And, no, you don't need to have a job in IT to handle all of the complexities. I use HQ Player and its internal convolution engine for room correction. It works seamlessly with both DSD native source files and PCM source files. I can output all files with room corrections all at DSD128 on a 4 year old iMac (which uses a relatively old i7 2600). I don't have a DAC that supports DSD512, nor would my current processor handle it. But edbk says DSD512 with upsampling and room correction in HQPlayer works on his 6700K, see post #190 in the thread Design a PC/Server for ROON and HQ Player. I use room correction filters generated by Audiolense XO, which is similar to Acourate. You upload the filters (spit into mono channels) into HQPlayer via the Matrix menus option. Miska has previously said that the matrix processing and convolution engine processing are done on DSD source files without any conversion of of the DSD source to PCM.
  11. Miska, just to let you know that the link to download NAA from signalyst.com (which redirects to https://www.signalyst.eu/bins/naa/v3/) is still down.
  12. Hi, Is there a way to disable the “Auto” setting (at least in the PCM / SDM menu) so to force HQ Player to output PCM or SDM/DSD permanently? You can manually change the setting on the playback screen, but every now and then HQPlayer starts with “Auto” selected. I run HQ Player in two different environments. In the first setup it is essential that HQP plays in PCM in the second setup my preference is to play everything as SDM / DSD. 1. In the home living room setup HQP runs on a headless Mac Mini in another room and plays via a NAA (mRendu) which is connected to a USB to AES converter (Gustard U12) as my DAC (Weiss DAC202) does not accept USB and does not recognise DSD DOP via spdif. The problem is that HQ Player thinks that the DAC is DSD capable as it only “sees” the the USB to AES/spdif converter (U12) which HQ Player knows is DSD capable. The USB to AES/spdif converter (U12) simply passes through the signal and does not convert DSD to PCM (and I would want any conversion done by HQPlayer in any event). But the DAC is not DSD capable. So when HQ Player is in Auto mode and plays back a DSD file HQ Player outputs a DSD stream, which is played back as full volume white noise by the DAC, which it is pretty painful to the ear (and potentially damaging to the equipment). It is not something you want to happen when other members of the family are in the room. Naturally, I have selected the PCM option on the playback screen. Most of the time when the computer is rebooted, HQ Player remembers that setting, but every now and then it starts with HQ Player in “Auto” mode for both the sample rate and the PCM / SDM output mode selection. The preferences file does not seem to be corrupted, as the options selected in the preferences window are retained. (On the preferences page all of the check boxes are unchecked, pcm: polysinc, NS9, 192000, “DAC bits” is set to 24.) My music library includes all common sample rates for both PCM and DSD. 2. In the work setup HQPlayer (again running on a Mac) links to a DSD capable DAC (Exasound e12) via NAA on a Windows 10 computer. I would like HQP to always playback via SDM/DSD on this machine. Again, I have selected SDM/DSD on the playback screen But occasionally, HQPlayer starts up with Auto selected on the playback screen and, when that occurs, and HQ Player receives a PCM file it plays back as PCM not SDM/DSD. As HQP runs on a headless machine (with Roon server), with the music controlled remotely via Roon from my work computer, it is a nuisance to go in and manually change the settings back to SDM/DSD. Ideally there would be option in the Preferences menu to output only PCM or output only DSD. But in the meantime is there any way to disable the Auto output mode setting or force HQP to open with the preferred output mode? I don’t recall this happening, prior to the introduction of the “Auto” output mode settings earlier this year. Thanks
  13. I agree with Musicophile’s list of Reference Recordings, Linn, Channel Classics, Pentatone, BIS, Harmonia Mundi, Hyperion, and Alpha. In addition, I would add the following smaller labels as ones that generally making excellent quality recordings, with quality being more variable from album to album as you go down the list: Ramée Ricercar Arts Productions Alia Vox Aeon Zig-Zag Territoires Ligia Mirare Glossa Da Capo Capriccio Naïve
  14. Patatorz, I experimented with JRiver on a QNAP HS-251 yesterday. I connected a monitor via HDMI to do the initial JRiver setup in HD Station. After the initial setup you do not need to keep the monitor attached. You simply control JRiver via JRemote or another app of your choice. JRiver on QNAP was able to stream via UPNP to My Lumin D1 without any problems being controlled by the JRemote. For the initial setup, you need a monitor, but do not need a mouse or keyboard as you can use the free Qremote apps on iOS or Andriod for that https://itunes.apple.com/app/qremote-by-qnap/id583756822?mt=8 https://play.google.com/store/apps/details?id=com.qnap.qremote&hl The difficulty with this approach is that where JRiver encounters and error, you won't know about it (and JRemote may become unresponsive depending upon the error) until you reconnect a monitor. The ideal solution would be if JRiver provided a full headless version where the setup of JRiver could be done via a weblink rather than needing a physically connected monitor. They have already done the hard work in porting it to QNAP. Still, it is a promising start.
