  1. I got fed up with Roon (specifically its metadata) and learned programming to develop my own music app which i now use on a daily basis
  2. I assume that would work but you should probably contact them ultimately to find out what they recommend for current UPL users.
  3. Yes, that is basically my understanding as well: - new DAC - not sure exactly what the "fractal" design is (but it sounds cool !). The DAC is a hybrid "therometer code dac", so an entirely new design - two adapters - one from USB to ElectroTOS and another from SPDIF/Toslink to ElectroTOS (and I understand USB will provide the best SQ) - new UPL, but available at a later date
  4. Here is a link to an additional post on DIY Audio by John Brown of ECDesigns explaining the various novel approaches they have developped and will include in their new products: https://www.diyaudio.com/forums/digital-line-level/79452-building-ultimate-nos-dac-using-tda1541a-744.html#post6031506 Very interesting developments that I plan on testing as soon as the new products are available.
  5. @mordante Could the OP or the administrator change the title of the thread to ECdesigns (add the s) ?
  6. No, I meant at whatever place the bits are transformed into an optical signal. Decoding of the signal in the DAC is relative to how the optical signal coming into the DAC gets transformmed and fed to the DAC chip. From what I understand, this process itself can generate "noise", and then there are of course jitter aspects - I am not "technical", but browsing through on-line litterature, interviews, you can get a grasp of what is going on and what DAC manufacturers have to deal with. My intention is not to generate any debates about this, I am just in a hopeful "wait and see" attitude...
  7. Optical, in itself, does not seem to be the magical key to high quality audio - after all, it has been in use for years. The devil is in the details, and the implementation is key: how the signal is generated in the source and the decoding of the signal in the DAC (and of course the ability of the DAC to transform precisely to analog all the information it is given). By addressing all those aspects, then we may see significant progress in digital audio - I believe this is what will be achieved in the coming years, and that we can finally reap the full benefits of digital audio (as I am convinced there is nothing wrong in the "data" itself and how it is stored in files, locally or on the cloud, or on CDs - recording quality being what it is). Who will get there first ? I sometimes wish all the experts in the field would just sit down together and get all this sorted out
  8. Here is what they have to say about their new product line: https://www.diyaudio.com/forums/digital-line-level/79452-building-ultimate-nos-dac-using-tda1541a-post5950855.html These will be using their new ElectroTos connection, which is an improved optical connection. No i2s connections, as far as I know. Projects are close to completion from what I understand (as of a few weeks ago). Just saw the link was already posted above.
  9. Apple, Google, Amazon, and Zigbee have announced they will be working on the development of standards for home automation. From what I understand, the idea is to have a common protocol for the discovery and control of hardware. I am very curious to understand what the implications will be for "audio". Does this mean that the "content" will be communicated as well using a common protocol ? Any insights ?
  10. I would like to add something, to "tie" these different comments together. What Chri's 3 selections have in commmon, it seems to me, is "simplicity". As Duke Ellington once said: "Simplicity is a most complex form", and that is true for audio systems as well - there is certainly a lot of complexity involved in the design of these systems. Now lets hope we see even more progess in the coming years, with outstanding audio quality of course.
  11. Well, that is another interesting debate For the coming decade I believe we will see "source immunity" and "format immunity" meaning DACs capable of offering similar quality for Redbook and high res. Let's see in 10 years (if we are still around) what will be in your "products of the decade". Vis à vis the négative effects of optical, they really depend on the implementation. The toslink cable is also a source of jitter signal degradation from what I understand.
  12. ECDesigns will be affordable as well. Their adapters will be compatible with toslink inputs of most DACs. Can you tell us more about your project ?
  13. The one mentioned by Raimund Heubel, PSAudio I believe, and ECDesigns (the only one I am familiar with). Could be others.
  14. @vortecjr I have been using only ECDesigns equipment, so if you are referring to PSAudio I have no idea. ECDesigns is finalizing new products which should be available in a couple months. Their new DAC will use this ElectroTos interlink (which I am using now in a prototype version, between their UPL source and their current MOS DAC). The led is at the DAC end of the cable, to put it simply, but in their latest implementation they have further improved the circuits that generate the signal in the source and decode it in the DAC, from what I understand. They will be offering adapters for sources with usb, toslink, or coax digital outputs. The source immunity may not be perfect, but we are getting closer, I believe. This is all mentioned in their thread on Diyaudio. Something to keep an eye on.
