  1. Did you build your PC yourself? What is it?

    For those looking for completely silent, yet powerful computing, there's a Belgian company, Calyos, on Kickstarter using pumpless and fanless phase-change technology. The cooling blocks can handle up to 1000W each, although they are limited by the size of the radiators, and the PSUs. The set up can handle up to a GTX1080ti GPU and essentially the most powerful Intel CPUs. They've already reached their Kickstarter funding goal, so now it remains to be seen how the actual deliveries, due in September, perform:
  2. Article: Aurender A10 Review

    I thought the 24/96 version, or SACD/DSD versions would be fantastic, offering greater fidelity and dynamic range. I then check the DR database, and am appalled that the greatest DR versions are the Redbook CD editions from 1984-1992. From then on it's all downhill. The 2003 version is found on DVD-A or SACD. The DVD-A 24/96, on a scale that goes from 1-20, lists a DR of 11, peak of 13, peak of 12. The SACD version even worse, with a DR of 9. Meanwhile those 1984-1992 CD versions are listed at DR 13, with peaks of 16. Perhaps it doesn't matter for an acoustic rendition, nevertheless, really disappointing.

  3. Article: The Revenge of Analog: An Editorial and Review

    Digital and computer controlled audio made my day, made me spend 30-40x more money on the sound system, and enjoy it way more. I'm glad I got to experience what's possible. Today incredible performance is available for far less. That said, I remember finding an obscure LP record, an almost impossible to find record, second hand. A woman I was interested in wanted it for her birthday. What a find. First time it played, red dust literally came flying out of the tracks. LP record covers were great, too. And you had to care for the records themselves, baby them, turn them over etc. Yes, digital nostalgia. As soon as it's 100% streaming the CD will be brought back with reverence. That shiny little silver disc. Pucks to keep them in place as they spin.
  4. Article: RAW: Roon Audio Workshop - Wrap-Up

    You list the audio system components they used. What about those acoustic wall panels, what brand are they?
  5. Article: exaSound PlayPoint Network Audio Player Review

    Interesting. A suggestion I have is to publish an image of the audio chain in a flow diagram, or in this case, the alternative audio chains make it faster to read, and also to compare various set ups suggested in different reviews.
  6. HQ Player

    So anyone else, then, is convolution with HQPlayer done on the GPU? Will that require another GPU for graphics work if HQPlayer's convolution engine is used with multichannel and Room Correction?
  7. HQ Player

    A question for Miska, I'm contemplating using AudioVero's Acourate DRC. They also offer a convolver, which comes highly recommended by some users. However, a convolver is already part of the HQPlayer. How does the HQPlayer convolution engine compare to the one offered by Acourate? Is the convolution done on the GPU? For the time being I only listen to PCM files, max 24/96 resolution.
  8. MQA at CES

    I stand corrected.
  9. MQA at CES

    Yes, Tidal being owned by artists is a driving force. The risk is still there. If there's cost and it's not covered by return, it's a gamble, or in business speak, a calculated risk. If the return is guaranteed, i e consumer uptake it guaranteed, it's not a gamble, but then everyone will be on board. It's far too early to say the risk is gone. Hence, for Tidal, it's a gamble. As for degradation or not, I guess that can be measured somehow, or else it is indeed a myth, or anecdotal evidence. BTW, markets are usually free only at the beginning, everyone in a "free" market will do everything they can do to make it less free in order to avoid simply competing on price, ending up with near zero profit. Frequently markets end up divided in blocks, oligopolies.
  10. MQA at CES

    Except Apple, and Dolby plus a few others, I guess?
  11. MQA at CES

    Yes, exactly mass market = critical mass. How large a base does Tidal have? 700.000-1.000.000 is the estimate I got from a quick Google search. If no competitor offers an alternative, which I believe to be unlikely, they could corner the audiophile online segment. This audiophile market is likely to be fragmented in terms of taste and preference, so volume will in some cases be low (although how that influences isn't totally transparent for streaming services), and I guess distribution rights therefore will be sold to others, offering the material in non MQA for the most part. Some artists may remain on MQA only. This is speculation of course, and S substitution curves can be difficult to predict. So to get the mass market beyond Tidal Meridian has to get the big hardware producers on board, and phone manufacturers as well. Phones would be the way to the mass market.
  12. MQA at CES

    MQA is in business strategy terms creating a barrier to entry, and a barrier to exit once inside. This strategy is totally obvious regardless of any hypothetically technical merit of MQA. The latter is not proven, and can certainly be questioned based on the tests carried out here and elsewhere. Creating such barriers is brilliant business as Porter, Dolby and THX have proven. As for me, I use multiple powerDACs. So I'll have to replace them all to get MQA certified DACs and new amplifiers as well. This is a very easy choice for me: no Tidal streaming. In the long run MQA can of course succeed, if it reaches critical mass and new material is exclusively released on MQA. While it's certainly a big strategic upside for Meridian, that's not necessarily so for Tidal. Tidal is the one gambling here. To minimize the risk, the smart thing would of course be to offer FLAC streaming in parallel, and then progressively track the MQA uptake, or differentiate by price. Errors have been made before, and the digital online landscape is riddled with corpses.
  13. Article: CES 2016 Wrap-up

    Yep, like I said usually it's bass or standing waves that messes stuff up, the ESL is usually pretty forgiving, even in small rooms. It's still incompetence to demo a speaker after so much work and investment and failing to take care of the basics. The tech is here today, as we all know. In fact it's been available for over 15 years. It's just disappointing they botch it.
  14. Article: CES 2016 Wrap-up

    I don't know that an ESL is particularly hard to set up in a small room as long as care is taken with the rear reflection. It would have to be a tiny, tiny room to blame the room for poor sound. Usually it's bass or standing waves that messes stuff up. From the shot it looks like there are blinds behind the speakers, better than a bare wall, or worse, glass, so the rear reflection should partly be taken care of. The Martin Logan management sound incompetent to me, can't create a good sounding demo for their $80,000 speakers? Years spent on development, on design, and then fail at the basics? Everyone with any acoustics knowledge at all knows that the room influences the sound, and they just have to deal with it.
  15. New Plex H5 gen 2 server HTPC

    Wow, what an inspirational build, and great pictures! The great thing with the HDPlex HD5 is the possibility to passively cool the GPU, that's for sure. number8, I wonder if you could do me a favor and measure: the distance from the top of the base of the GPU's aluminum top plate, i e from the aluminum plate, excluding the fins, to the top of the case? What is that distance? Also, if possible, could you measure how far from the rear of the case to the aluminum top plate center, and from the left side of the case, including the fins, to the left side of the aluminum top plate?
