  1. Thanks. US$299 seems a lot to me for a device that doesn't seem to provide significantly better performance.
  2. Thanks Mansr for the review. My question is: is this device an improvement over the typical integrated audio output of a laptop (regarding measurements)? Is there any objective reason to use the DF cobalt with a MacBook Pro or some decent android phone already equipped with analog outs? Thanks again, Jorge
  3. So you are saying that with VLC it is possible to decode multichannel audio from AC3-encoded audio files, but not the AC3 audio from dvd's. If that's the case, perhaps PowerDVD from Cyberlink is an option. There is a 30 days trial version here, with some limitations in its capabilities however. Regards, Jorge
  4. I'm not 100% sure, but probably VLC player can do the routing You need in it's config options for audio. If not, perhaps some paid player from Cyberlink is an option also. Jorge
  5. Read again, the Roon quote describes two different things: first, as an introduction, the quote describes conversion from dsd to pcm and, subsequently, it describes the process they use to process dsd, making it clear that this differs from the first precisely in that downsampling is avoided.
  6. I think you misunderstood the quote brought by @firedog in that the Roon person specifically said that they are not downsampling from the dsd rate when they are processing dsd. Quoting now, "it maintains the DSD sample rate".
  7. Congratulations for this anniversary!! A great community you have built here. For me, especially great reads have been the many threads on dsd some years back (to DSD or not... and others), including the always interesting contributions from Miska, C.Hansen, mansr, Jud, PeterSt and many other contributors. Also the threads obout some interesting gear have been fun reads (the gigantic thread about the mytek 192 dsd da converter, comes to mind). Hope CA is here for many more years. Regards, Jorge

    DSD 256 Recorder

    I think the Korg DSDAC10R mentoned above does dsd128 max. They state 2.8 or 5.6 Mhz in the product page
  9. Have a look at madisound.com They sell drivers from various brands (also kits) and also can help with crossover design. There is partsexpress.com also. Both carry drivers from seas or scanspeak or many others Regards
  10. Until one year ago I used the mobile web interface, as there was no app for the WindowsPhone I used at the time. It was fast and easy to read, but the main problem was that images attached to posts were not displayed. Hope the new web interface handle images better. If this is well implemented, I will be happy to uninstall the ca app from my current Android phone. Regards, Jorge
  11. Does it have to be a usb audio interface? There are many exellent portable digital recorders equipped with line inputs which you can connect to your phono preamp, from Tascam, Zoom, M-Audio and Sony, among others. These record usually to SD cards, but can also connect to a PC for usb transfer via cable. The sony pcm D-100 even records to DSD (in adition to all the common pcm rates). This (and many others as well) has also suppossedly good built-in microphones in case you want to record a musician friend, so use is not limited to record vinyl. I'm sure you could find good units in price range fron 100 to 1000 us dolars. Regards Jorge Sent from my E2303 using Computer Audiophile mobile app
  12. I think this was the intended address, fig.6 in: Mytek HiFi Brooklyn D/A processor–headphone amplifier Measurements | Stereophile.com
  13. First thing is to be sure that the pc is outputting its audio to its hdmi port. Usually this is automatically configuerd by the pc OS when the hdmi cable is connected. However some times it is not, and you have to manually set the output to the hdmi. Second. In my LG, the optical out must be manually enabled in a config menu in the Tv. Iow, this output isn't working all the time, only when you enable it. Hope this help Jorge Sent from my E2303 using Computer Audiophile mobile app
  14. Hi Chris, Do you intend to compare the MQA vs the non-MQA version of these music files but using a standard DAC (ie a DAC without an MQA decoder)? This comparison would be useful to many people that are not prepared or willing to invest in a new MQA-approved DAC. Thanks, Jorge
  15. Thanks for the opportunity My questions: I. There are many hobby recordists who use fairly respectable semi-pro (or even pro) digital recorders. In many cases these recordings are then subjected to some amount of post processing in the computer (eq, dynamics or some other digital processing for cleaning or “improving” the recorded audio) with the aid of plug-ins in DAWs: -- Will the MQA de-blurring algorithm be available for purchase in plug-in form as a standalone package (i.e. without the “audio origami” folding compression technique)? If yes, this will allow for these kind of users to compare the MQA de-blur algorithm with offers from other manufacturers (like Waves or Izotope) that also claim to help to clean or improve the recorded digital audio. II. It has been stated that MQA enabled ADCs will be available for the pro market (think Mytek): -- Will these ADCs be delta-sigma based with decimation for PCM output? -- If yes, where in the conversion stage will be MQA participating with its de-blurring technology: is it in the decimation stage? -- As a summary: what will be the main technological difference between a top-nocht MQA certified ADC and the already existing top-notch non-certified ADCs like Meitner, Merging, Metric Halo or Apogee. III. To me, it is very important to allow every content creator work in the format in which feels more comfortable with. While the majority of music producers and recording engineers work mainly in the PCM world, there are some that prefer to work instead in a purely DSD domain (or some analog-DSD combination). Of course, there is conversion software that allows to release a final musical product in any format, but my question is: -- Does the MQA technology, as a whole, fit in a production environment based mainly or purely in DSD? -- If yes, in what way? Thanks, Jorge
